              Notes to Condensed Consolidated Financial Statements
                                  June 30, 2003


Note 1. Organization and Operations

      provides   water  utility  and  other  related   services  in  California,
      Washington,  New Mexico and Hawaii through its wholly owned  subsidiaries.
      California  Water Service  Company (Cal Water),  Washington  Water Service

      utility-related services.

      The Company  operates  primarily in one business  segment  providing water
      utility services.


Note 2. Summary of Significant Accounting Policies

      The  interim  financial  information  is  unaudited.  In  the  opinion  of
      management,  the accompanying  condensed consolidated financial statements
      reflect all adjustments that are necessary to provide a fair  presentation
      of the results for the periods presented.  The adjustments consist only of
      normal  recurring  adjustments.  The results  for interim  periods are not
      necessarily  indicative  of the results of the entire year.  The condensed
      consolidated  financial  statements should be read in conjunction with the
      Company's  consolidated  financial  statements for the year ended December
      31,  2002  included  in its Form  10-K as filed  with the  Securities  and
      Exchange Commission on March 25, 2003.


Note 3.  Stock-based Compensation

      The Company  has a  stockholder  approved  Long-Term  Incentive  Plan that
      allows granting of nonqualified stock options. The Company has adopted the
      disclosure  requirements  of Statement of Financial  Accounting  Standards
      (SFAS) No. 123 "Accounting for  Stock-Based  Compensation,"  as amended by
      SFAS  No.  148  "Accounting  for  Stock-Based  Compensation  -  Transition
      Disclosure - An Amendment of FASB  Statement No. 123", and as permitted by
      the  statement,  applies  Accounting  Principles  Board  Opinion  No.  25,
      "Accounting  for Stock Issued to Employees," for its plan. All outstanding
      options have an exercise  price equal to the market price on the date they
      were granted.  No compensation  expense was recorded for the three and six
      month  periods ended June 30, 2003 and 2002 related to stock  options.  No
      options were granted during the three and six month periods ended June 30,
      2003.

      The table  below  illustrates  the effect on net income and  earnings  per
      share as if the company had applied the fair value  recognition  provision
      of SFAS No. 123 to employee compensation.

Note 4.  Seasonal Business

     Due to the seasonal nature of the water  business,  the results for interim
     periods  are not  indicative  of the  results  for a  twelve-month  period.
     Revenue and income are generally higher in the warm, dry summer months when
     water  usage and sales are  greater.  Revenue  and  income are lower in the
     winter months when cooler temperatures and increased rainfall curtail water
     usage and sales.

Note 5.  Earnings Per Share Calculations

     The computations of basic and diluted earnings per share are noted below.

     Options to purchase  107,000  shares of common  stock for the three and six
     month  periods ended June 30, 2002 were excluded from the diluted per share
     calculation  due to their  anti-dilutive  effect.  No  exclusions  from the
     diluted per share calculation were made for the three and six month periods
     ended June 30, 2003.

Note 9.  New Accounting Standards

      In June 2001, the Financial  Accounting  Standards  Board ("FASB")  issued
      Statement of Accounting  Standards ("SFAS") No. 143, "Accounting for Asset
      Retirement  Obligations,"  which applies to legal  obligations  associated
      with  the  retirement  of  long-lived  assets  and  the  associated  asset
      retirement costs. The statement was effective for the Company in the first
      quarter  of 2003.  The  adoption  of SFAS No.  143 did not have a material
      impact to the Company's results of operations or cash flows.

      In July  2002,  the  FASB  issued  SFAS No.  146,  "Accounting  for  Costs
      Associated  with Exit or Disposal  Activities."  This Statement  addresses
      financial  accounting  and  reporting  for costs  associated  with exit or
      disposal  activities and nullifies Emerging Issues Task Force (EITF) Issue
      No. 94-3, "Liability Recognition for Certain Employee Termination Benefits
      and Other Costs to Exit an Activity (including Certain Costs Incurred in a
      Restructuring)."  This  Statement  requires  that a  liability  for  costs
      associated  with an exit or disposal  activity be recognized  and measured
      initially  at  fair  value  only  when  the  liability  is  incurred.  The
      provisions of this statement are effective for exit or disposal activities
      that are initiated  after  December 31, 2002. The adoption of SFAS No. 146
      did not impact the Company's financial position,  results of operations or
      cash flows.

      In November  2002,  the FASB issued  Interpretation  No. 45,  "Guarantors'
      Accounting and Disclosure Requirements for Guarantees,  Including Indirect
      Guarantees of Indebtedness of Others." Interpretation No. 45 requires that
      a liability be recognized at the time a company issues a guarantee for the
      fair value of the obligations assumed under certain guarantee  agreements.
      Interpretation No. 45 is effective for guarantees issued or modified after
      December 31,  2002.  The  disclosure  requirements  of the  Interpretation
      expand the disclosures required by a guarantor about its obligations under
      a guarantee. The adoption of the accounting requirements of Interpretation
      No.  45 did not  impact  the  Company's  financial  position,  results  of
      operations or cash flows.

      In January 2003, the FASB issued  Interpretation No. 46, "Consolidation of
      Variable Interest  Entities."  Interpretation No. 46 provides guidance for
      determining  when a primary  beneficiary  should  consolidate  a  variable
      interest  entity or  equivalent  structure  that  functions to support the
      activities of the primary beneficiary.  Interpretation No. 46 is effective
      for all new variable  interest  entities created or acquired after January
      31, 2003.  For variable  interest  entities  created or acquired  prior to
      February 1, 2003, the provisions of Interpretation  No. 46 must be applied
      during the first interim or annual period  beginning  after June 15, 2003.
      The  adoption  of  Interpretation  No.  46 did not  impact  the  Company's
      financial position, results of operations or cash flows.

      In April 2003, the FASB issued SFAS No. 149 "Amendment of Statement 133 on
      Derivative  Instruments and Hedging Activities".  The standard impacts the
      accounting for certain  derivative  contracts  entered into after June 30,
      2003.  This  standard is effective for quarters  beginning  after June 15,
      2003.  The Company  currently  does not enter into  derivative  or hedging
      contracts.  The adoption of SFAS No. 149 is not expected to have an impact
      on the Company's financial position, results of operations or cash flows.


                                       13


      In May  2003,  the  FASB  issued  SFAS No.  150  "Accounting  for  Certain
      Financial   Instruments  with  Characteristics  of  both  Liabilities  and
      Equity".  The statement  establishes  standards for the classification and
      measurement of certain financial  instruments with characteristics of both
      liabilities   and  equity.   The  statement  is  effective  for  financial
      instruments entered into after May 31, 2003 and is otherwise effective for
      quarters  beginning  after  June 15,  2003.  The  Company  has not  issued
      financial  instruments that have  characteristics  of both liabilities and
      equity.  The adoption of SFAS No. 150 is not expected to have an impact on
      the Company's financial position, results of operations or cash flows.

Note 10.  Subsequent Events

     Financing

      On July 11, 2003, the Company's shelf registration statement providing for
      the  issuance  from time to time of up to  $120,000,000  in common  stock,
      preferred stock and/or debt securities,  became effective. The Company may
      issue any of these  types of  securities  until the amount  registered  is
      exhausted,  and will add the net proceeds from the sale of the  securities
      to our general funds to be used for general corporate purposes,  which may
      include investment in subsidiaries, working capital, capital expenditures,
      repayment of  short-term  borrowings,  refinancing  of existing  long-term
      debt, acquisitions and other business opportunities.

      On August 4, 2003, the Company  announced the issuance of 1,750,000 shares
      of  common  stock  from the shelf  registration  statement.  A  prospectus
      supplement and  prospectus  were filed with the SEC under rule 424 (b) (2)
      on August 5,  2003.  The shares  were sold at $26.25  per  share.  The net
      proceeds to the Company were approximately $44 million and the transaction
      was closed on August 7, 2003.  The funds were used to pay down  short-term
      borrowings and to invest in short-term  money market  instruments  pending
      their  use for  general  corporate  purposes.  Additional  information  is
      incorporated  by  reference  to a Form 8-K filed on August 6, 2003.  After
      issuance of the 1,750,000 shares,  there remains $74,062,500 in securities
      under the shelf registration, which are available for future issuance.

Item 2

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

FORWARD LOOKING STATEMENTS

      This quarterly report,  including all documents incorporated by reference,
      may contain forward-looking statements. The forward-looking statements are
      intended to qualify for "safe-harbor" treatment established by the Private
      Securities  Reform Act of 1995.  Forward-looking  statements  are based on
      currently available information,  expectations, estimates, assumptions and
      projections,  and  management's  judgment  about  the  company,  the water
      utility  industry and general economic  conditions.  Words like "expects",
      "intends",  "plans", "believes",  "estimates",  "assumes",  "anticipates",
      "projects",  "predicts",  "forecasts"  or  variations  of  these  words or
      similar expressions are intended to identify  forward-looking  statements.
      The  forward-looking  statements are not guarantees of future performance.
      They are based on numerous assumptions that we believe are reasonable, but
      they  are  open to a wide  range  of  uncertainties  and  business  risks.
      Consequently, actual results may vary materially from what is contained in
      a forward-looking statement.  Factors which may cause actual results to be
      different  than  expected  or  anticipated   include:   governmental   and
      regulatory  commissions'  decisions;  changes in  regulatory  commissions'
      policies and procedures; the timeliness of regulatory commissions' actions
      concerning rate relief;  new  legislation;  electric power  interruptions;
      increases in suppliers' prices and the availability of supplies  including
      water and power;  fluctuations in interest rates; changes in environmental
      compliance  and water quality  requirements;  the ability to  successfully
      implement  business  plans;  changes in customer  water use patterns;  the
      impact  of  weather  on water  sales  and  operating  results;  access  to
      sufficient capital on satisfactory  terms; civil disturbances or terrorist
      threats or acts, or apprehension about possible future occurrences of acts
      of this  type;  the  involvement  of the  United  States  in war or  other
      hostilities;  restrictive covenants in or changes to the credit ratings on
      our  current or future debt that could  increase  our  financing  costs or
      affect our ability to borrow, make payments on debt or pay dividends; and,
      other  risks  and  unforeseen  events.  When  considering  forward-looking
      statements,  you should keep in mind the cautionary statements included in
      this  paragraph.  We assume no  obligation  to provide  public  updates of
      forward-looking statements.


CRITICAL ACCOUNTING POLICIES

      We  maintain  our  accounting   records  in  accordance   with  accounting
      principles  generally  accepted  in the United  States of  America  and as
      directed  by the  regulatory  commissions  to  which we are  subject.  The
      process of preparing financial statements requires the use of estimates on
      the part of  management.  The estimates  used by  management  are based on
      historical   experience  and  an   understanding   of  current  facts  and
      circumstances.  Management believes that the following accounting policies
      are  critical  because  they  involve a higher  degree of  complexity  and
      judgement and can have a material  impact on our results of operations and
      financial condition.


                                       15


Revenue Recognition

      Revenue from metered  customers  includes  billings to customers  based on
      monthly  meter  readings  plus an  estimate  for water  used  between  the
      customer's  last meter reading and the end of the accounting  period.  The
      unbilled  revenue  amount is  recorded  as a current  asset on the balance
      sheet under the caption "Unbilled Revenue." At June 30, 2003, the unbilled
      revenue  amount was $10.0  million and at December 31, 2002 the amount was
      $8.0 million.  The unbilled  revenue amount is generally higher during the
      summer months when water sales are higher. The amount recorded as unbilled
      revenue  varies  depending  on water usage in the  preceding  period,  the
      number of days between meter reads for each billing cycle,  and the number
      of days between each cycle's meter  reading and the end of the  accounting
      cycle.

      Flat rate  customers are billed in advance at the beginning of the service
      period.  The revenue is prorated so that the portion of revenue applicable
      to the current accounting period is included in that period's revenue. The
      portion related to a subsequent  accounting period is recorded as unearned
      revenue on the balance sheet and  recognized as revenue when earned in the
      subsequent  accounting  period.  The unearned  revenue  liability was $1.9
      million at June 30,  2003 and $1.7  million at  December  31,  2002.  This
      liability is included in "accrued  expenses and other  liabilities" on the
      balance sheet.

      Revenues from  non-regulated  activities are recognized when services have
      been rendered, when title has transferred to the buyer or ratable over the
      term of  agreement  for  lease  contracts.  For  construction  and  design
      services, revenue is generally recognized on the complete contract method,
      as most projects are completed in less than three months. One construction
      and design project spans  multiple  years and revenue is recognized  using
      the  percentage-of-completion  method based on a zero profit  margin until
      project completion.

Expense Balancing and Memorandum Accounts

      Expense-balancing  accounts and memorandum accounts (offsetable  expenses)
      represent  costs  incurred,  but not billed to our customers.  The amounts
      included  in these  accounts  relate to rate  increases  charged  to us by
      suppliers of purchased  water and purchased  power,  and increases in pump
      taxes. We do not record  expense-balancing  or memorandum  accounts in our
      financial  statements  as  revenue,  nor  record a  receivable  until  the
      California Public Utilities Commission ("CPUC") has authorized recovery of
      the higher costs and  customers  have been  billed.  The accounts are only
      used to track the higher costs.  The cost increases,  which are beyond our
      control,  are referred to as "offsetable  expenses"  because under certain
      circumstances  they are  recoverable  from customers in future offset rate
      increases.

      Historically,  offset rate increases enabled water utilities to recover as
      a pass-through, cost increases for offsetable expenses that were not known
      or anticipated  when customer rates were  established  and were beyond the
      utility's  control.  In December  2002,  the CPUC  issued a decision  that
      designated  certain offsetable  expenses as frozen.  These were offsetable
      expenses  incurred  prior to November 29, 2001. In May 2003, we received a
      decision  from the CPUC  allowing  recovery of $5.4 million of  offsetable
      expenses,  of which $3.6 million  will be collected  from May 2003 through
      May 2004 and $1.8  million  will be  collected  from May 2004  through May
      2005. Partially offsetting this amount will be a refund of $0.8 million to
      one  district  that will be  processed  from June 2003  through June 2004.
      Certain other amounts totaling approximately $0.7 million were not allowed
      and will be incorporated into future rate case filings.


                                       16


      In June 2003, the CPUC issued a decision  allowing water utility companies
      to request recovery of  "balancing-type  memorandum  accounts",  which are
      primarily  comprised of higher  electricity cost incurred between November
      29, 2001 and December 31, 2002. Unlike the recovery of such costs prior to
      November 29, 2001, certain  limitations will apply. The primary limitation
      is  recovery  will not be  allowed  if a  district  earned  more  than its
      authorized  rate of return for that year.  We intend to file  requests for
      approximately  $6 million in the third quarter of 2003. We cannot  predict
      the amount that will be authorized.  We expect a decision prior to the end
      of 2003.

      A net $0.4 million of expense balancing account recovery was recognized in
      revenue for the quarter ended June 30, 2003. At June 30, 2003,  the amount
      included in the  offsetable  expense  accounts not yet recovered was $10.2
      million,  which reflects  adjustments  from the decisions  noted above and
      reductions for amounts recovered through customer billings.

Regulated Utility Accounting

      Because we operate extensively in a regulated business,  we are subject to
      the provisions of Statement of Financial  Accounting  Standards (SFAS) No.
      71,   "Accounting  for  the  Effects  of  Certain  Types  of  Regulation."
      Regulators establish rates that are expected to permit the recovery of the
      cost of service and a return on investment.  In the event a portion of our
      operations  were no longer  subject to the  provisions  of SFAS No. 71, we
      would be required to write off related  regulatory  assets and liabilities
      that are not specifically  recoverable and determine if other assets might
      be impaired.  If a regulatory  commission determined that a portion of our
      assets was not  recoverable  in  customer  rates,  we would be required to
      determine  if we had  suffered an asset  impairment  that would  require a
      write-down  in the  assets'  valuation.  There  have  been no  such  asset
      impairments as of June 30, 2003.

Income Taxes

      Significant   judgment  by  management  is  required  in  determining  the
      provision for income taxes.  The  preparation  of  consolidated  financial
      statements  requires the  estimation  of income tax  expense.  The process
      involves the  estimating of current tax exposure  together with  assessing
      temporary differences resulting from different treatment of certain items,
      such as depreciation,  for tax and financial  statement  reporting.  These
      differences  result in  deferred  tax  assets and  liabilities,  which are
      reported  in the  consolidated  balance  sheet.  We must also  assess  the
      likelihood  that  deferred tax assets will be recovered in future  taxable
      income,  and to the extent  recovery is  unlikely,  a valuation  allowance
      would be  recorded.  If a  valuation  allowance  were  required,  it could
      significantly  increase  income  tax  expense.  In  management's  view,  a
      valuation allowance is not required as of June 30, 2003.

Pension Benefits

      We incur costs associated with our pension and postretirement  health care
      benefits plans. To measure the expense of these benefits,  management must
      estimate  compensation  increases,  mortality  rates,  future  health cost
      increases  and discount  rates used to value  related  liabilities  and to
      determine  appropriate  funding.  Different  estimates  used by management
      could result in significant  variances in the cost  recognized for pension
      benefit  plans.  The estimates  used are based on  historical  experience,
      current facts, future  expectations and  recommendations


                                       17


      from independent  advisors and actuaries.  We use an investment advisor to
      provide  expert advice in managing the plan's  investments.  We anticipate
      any  increase in funding for the  pension and  postretirement  health care
      benefits plans will be recovered in future customer rates.


RESULTS OF SECOND QUARTER 2003 OPERATIONS

     Second quarter net income was $4.6 million,  equivalent to $0.30 per common
     share on a diluted basis compared to the $6.6 million or $0.43 per share on
     a diluted basis earned in the second quarter of 2002.

Operating Revenue

     Operating  revenue  decreased $1.2 million or 2% to $68.0 million.  Weather
     had a  significant  influence on customer  water usage.  Temperatures  were
     approximately  the  same  as the  prior  year  for  our  markets.  However,
     precipitation  was much higher compared to the prior year,  (greater than 3
     times last year's  amount),  which had a negative  influence on usage.  The
     month of April in particular had significantly  higher  precipitation.  The
     factors that impacted the operating revenue decrease for the second quarter
     of 2003 are presented in the following table:

         Decreased usage by existing customers          ($4,546,000)
         Rate increases                                   1,895,000
         Usage by new customers                           1,462,000
                                                        ------------
              Net operating revenue decrease            ($1,189,000)
                                                        ============

      Operating  revenue  from  rate  increases  includes  step  rate  increases
      effective  in  January  2003,  increases  from 2  advice  letters  for the
      Bakersfield  plant,  increases  for  Washington  Water and  increases  for
      balancing  accounts.  Usage by new  customers  includes  $454,000  for New
      Mexico Water as these  operations were acquired in July 2002, and $508,000
      for Hawaii Water, which was acquired on April 30, 2003.

Total Operating Expenses

      Total operating  expenses were $60,446,000 for the three months ended June
      30, 2003 versus  $60,778,000  for the same period in 2002,  a 1% decrease.
      This   category  is  comprised   of   operations   expense,   maintenance,
      depreciation/amortization, income taxes and property/other taxes.

      Operations  expense increased  $363,000 or 1% from the prior year. A major
      component  of this expense is water  production  costs.  Water  production
      costs  consists of purchased  water,  purchased  power and pump taxes.  It
      represents the largest component of operations expense. During the current
      quarter,  these costs accounted for 57% of total operations expense. Water
      costs  decreased  4% compared to last year.  Water  production  quantities
      decreased  6% due to the lower water usage by existing  customers  and was
      partially offset by sales to new customers.  Well production  provided 51%
      of the water supply, 48% was purchased from wholesale suppliers and 1% was
      developed  through our surface water treatment  plants.  The components of
      water  production  costs and changes from the second  quarter of last year
      are shown in the table below:


                                       18

                                                   -----------     ------------
         Purchased water                           $19,298,000       ($764,000)
         Purchased power                             5,360,000          26,000
         Pump taxes                                  1,576,000        (269,000)
                                                   -----------     ------------
              Total                                $26,234,000     ($1,007,000)
                                                   ===========     ============

     Purchased  water and pump taxes were  lower due to the  decreased  usage by
     customers.  Purchased power,  which is used mainly for pumping equipment at
     wells and  distribution  lines,  increased  due to higher  rates  that were
     partially offset by lower usage.

     Other costs  included in  operations  expense  are wages,  benefits,  water
     treatment,  water supply,  customer  services  costs and general  corporate
     expenses. Wages for union employees increased 1% effective January 1, 2003.
     Overall  labor costs  increased  5% due to  replacing  personnel  at higher
     salaries  and adding labor  related to New Mexico  Water and Hawaii  Water.
     Payroll costs charged to operations expense increased by $238,000.  Benefit
     costs increased  $929,000 for pension costs and higher medical claim costs.
     Part of the agreement with union employees included a change in the pension
     plan for the minimum payment amounts.  This change  increased  pension cost
     substantially,  increasing  68% from the prior year. At June 30, 2003 there
     were 810 employees and at June 2002 there were 788 employees.

     Other major items  driving the increase in  operations  expenses were water
     treatment/water  quality  expenses  ($215,000)  for  increased  testing and
     customer service expenses ($166,000) caused by increases in bad debts.

     Maintenance  expense was $128,000 higher in the quarter ended June 30, 2003
     due to additional  maintenance required for mains, service line, meters and
     tank repairs.  Depreciation/amortization expense increased $449,000 because
     of the increase in utility plant assets.

     Federal and state income taxes decreased  $1,259,000 due to the decrease in
     taxable  income.  The effective tax rate was 42% in the current quarter and
     41% for the same quarter in the prior year.

Other Income and Expense

     Other income and expense was $1,517,000  net income  compared to $2,430,000
     net income in 2002,  a decrease of  $913,000.  The  decrease  was driven by
     lower sales of surplus real property that was partially offset by increases
     in income from  operating/maintenance  arrangements,  meter reading/billing
     services and rental income from cellular antenna leases.

Interest Expense

     Total  interest  expense  increased  $263,000 with  long-term debt interest
     increasing $202,000 and short-term interest expense increasing $61,000.

      Long-term  debt interest has three  components.  Interest  increased a net
      $482,000 because of the additional $40 million in senior notes issued. Our
      refinancing program resulted in reduced interest cost on approximately $60
      million  of debt that  produced  savings  of  $315,000.  This  savings  is
      embedded in the net interest cost increase.  Debt  amortization  increased
      $30,000 due to the new debt and the program to refinance certain long-term
      debt with  lower-cost  senior  notes.  Partially  offsetting  the interest
      increase   from  new  senior  notes  was  the  increase  of  $310,000  for
      capitalization  of interest related to construction  projects in progress.
      The amount of  construction  in progress  has  increased,  driven by large
      projects such as the Bakersfield treatment plant.

      Borrowings  under our short-term bank credit  agreement were higher during
      the second  quarter of this year compared to the same quarter in 2002. The
      average  interest rate on short-term debt was  approximately  2.8% in 2003
      compared  to  approximately  3.1% during the second  quarter in 2002.  The
      higher  borrowings  caused  short-term  interest  expense to  increase  by
      $61,000.


RESULTS OF SIX MONTHS ENDED JUNE 30, 2003

      Net  income  for the six  months  ended  June 30,  2003 was $3.8  million,
      equivalent  to $0.25 per common share on a diluted  basis  compared to the
      $8.5 million or $0.56 per share on a diluted basis earned in 2002.

Operating Revenue

      Operating revenue decreased $1.5 million or 1% to $119.3 million.  Weather
      had a significant  influence on customer  water usage.  Temperatures  were
      approximately  the  same  as the  prior  year  for our  markets.  However,
      precipitation  was much higher,  over two times the prior year  comparable
      period and had a negative  influence on usage.  The factors that  impacted
      the operating  revenue decrease for the six months ended June 30, 2003 are
      presented in the following table:

         Decreased usage by existing customers          ($6,433,000)
         Rate increases                                   2,742,000
         Usage by new customers                           2,202,000

              Net operating revenue decrease            ($1,489,000)
                                                        ============

      Operating  revenue  from  rate  increases  includes  step  rate  increases
      effective  in  January  2003,  increases  from 2  advice  letters  for the
      Bakersfield  plant,  increases  for  Washington  Water and  increases  for
      balancing  accounts.  Usage by new  customers  includes  $788,000  for New
      Mexico Water as these  operations were acquired in July 2002, and $508,000
      for Hawaii Water, which was acquired on April 30, 2003.

Total Operating Expenses

      Total operating  expenses were  $109,131,000 for the six months ended June
      30, 2003 versus  $107,036,000  for the same period in 2002, a 2% increase.
      This   category  is  comprised   of   operations   expense,   maintenance,
      depreciation/amortization, income taxes and property/other taxes.


                                       20


      Operations expense increased $3,421,000 or 3% from the prior year. A major
      component  of this expense is water  production  costs.  Water  production
      costs  consists of purchased  water,  purchased  power and pump taxes.  It
      represents  the  largest  component  of  operations  expense.  For the six
      months,  these costs accounted for 54% of total operations  expense,  down
      from 57% in the prior  year.  Water  costs  decreased  1% compared to last
      year.  Water  production  decreased  5% due to the  lower  water  usage by
      existing  customers  and was partially  offset by sales to new  customers.
      Well production  provided 50% of the water supply,  49% was purchased from
      wholesale  suppliers  and 1%  was  developed  through  our  surface  water
      treatment  plants.  The components of water  production  costs and changes
      from the six-month period of last year are shown in the table below:

                                                   Six Months
                                                    2003 Cost           Change
                                                   -----------        ----------
         Purchased water                           $33,700,000        ($252,000)
         Purchased power                             8,991,000           50,000
         Pump taxes                                  2,504,000         (293,000)
                                                   -----------        ----------
              Total                                $45,195,000        ($495,000)
                                                   ===========        ==========

      Purchased  water and pump taxes were lower due to the  decreased  usage by
      customers.  Purchased power, which is used mainly for pumping equipment at
      wells  and  distribution  lines  increased  due to  higher  rates and were
      partially offset by lower usage.

      Other costs  included in  operations  expense are wages,  benefits,  water
      treatment,  water supply,  customer  services costs and general  corporate
      expenses.  Wages for union  employees  increased 1%  effective  January 1,
      2003.  Overall  labor costs  increased  6% due to  replacing  personnel at
      higher  salaries and adding  labor  related to New Mexico Water and Hawaii
      Water.  Payroll costs charged to operations expense increased by $671,000.
      Benefit costs  increased  $1,806,000  for pension costs and higher medical
      claim costs. Part of the agreement with union employees  included a change
      in the pension plan for the minimum payment amounts. This change increased
      pension cost  substantially,  increasing  73% from the prior year. At June
      30,  2003  there  were  810  employees  and at June  2002  there  were 788
      employees.

      Other major items driving the increase in  operations  expenses were water
      treatment/water  quality  expenses  ($501,000)  for increased  testing and
      customer service expenses ($280,000) caused by increases in bad debts.

      Maintenance expense was $961,000 higher in the six-month period ended June
      30, 2003 due to additional  maintenance  required for mains, service line,
      meters  and  tank  repairs.  Depreciation/amortization  expense  increased
      $815,000 because of the increase in utility plant assets.

      Federal and state income taxes decreased $3,091,000 due to the decrease in
      taxable  income.  The  effective tax rate was 42% for the six month period
      and 41% for the same period in the prior year.


                                       21


Other Income and Expense

      Other income and expense was $2,680,000 net income  compared to $2,864,000
      net income in 2002,  a decrease of  $184,000.  The  decrease was driven by
      lower  sales of  surplus  real  property  that  was  partially  offset  by
      increases  in  income  from  operating/maintenance   arrangements,   meter
      reading/billing services and rental income from cellular antenna leases.

Interest Expense

      Total  interest  expense  increased  $962,000 with long-term debt interest
      increasing $848,000 and short-term interest expense increasing $114,000.

      Long-term debt interest has three components.  Interest increased $947,000
      because  of the  additional  $40  million  in  senior  notes  issued.  Our
      refinancing program resulted in reduced interest cost on approximately $60
      million  of debt that  produced  savings  of  $467,000.  This  savings  is
      embedded in the net interest cost increase.  Debt  amortization  increased
      $61,000 due to the new debt and the program to refinance certain long-term
      debt with  lower-cost  senior  notes.  Partially  offsetting  the interest
      increase   from  new  senior  notes  was  the  increase  of  $160,000  for
      capitalization  of interest related to construction  projects in progress.
      The amount of  construction  in progress  has  increased,  driven by large
      projects such as the Bakersfield treatment plant.

      Borrowings  under our short-term bank credit  agreement were higher during
      the first six  months of this year  compared  to the same  period in 2002.
      Average interest rates on short-term debt was  approximately  2.9% in 2003
      compared to a 3.4% rate in 2002. The higher  borrowings  caused short-term
      interest expense to increase by $114,000.


REGULATORY MATTERS

Rate Case Proceedings

      California  Water 2001 General Rate Case (GRC)  Applications - This filing
      was submitted in July 2001. A Draft of Proposed  Decision (DPD) was issued
      in January 2003 authorizing a $12.8 million annual revenue increase, which
      is less than the initial filing. In addition, the DPD decision authorizing
      a return on equity of 9.7% on 51.5% equity capitalization  (equity divided
      by equity and long term debt).  In April 2003,  the CPUC issued a decision
      to  establish   April  3,  2003  as  the  effective   date  for  the  2001
      applications. This is favorable to us, as revenues will not continue to be
      permanently  lost due to the delays in GRC decisions by the CPUC. Past GRC
      applications took approximately 10 months to receive a decision.  The 2001
      GRC filing is  currently  26 months old. We are unable to predict when the
      final decision will be issued, their composition or their financial impact
      on 2003 net revenues.

      Washington  Water  2002  GRC  Applications  -  Washington  Water  received
      approval  on its  application  effective  April  2002  for $1  million  of
      increased  rates  annually  to cover  higher  operating  costs and capital
      expenditures.

      California  Water 2002 GRC  Applications - In November 2002,  applications
      were filed for rate  increases of $1.3 million on an annual basis relating
      to three districts. Due to the delays by the CPUC decision-making process,
      we are unable to predict  when the final  decisions  and  rulings  will be
      issued, their composition or their financial impact on 2003 net revenues.


                                       22


      California  Water 2003 GRC  Applications  - In January 2003,  applications
      were filed for rate  increases of $8.2 million on an annual basis relating
      to four districts. In July, 2003 we submitted a preliminary GRC filing and
      the  application  is expected to be filed in  September  2003.  Due to the
      delays  by the  CPUC in the  decision-making  process,  we are  unable  to
      predict  when the  final  decisions  and  rulings  will be  issued,  their
      composition or their financial impact on 2003 net revenues.

      California  Water Advice Letters - Advice letters are used to request rate
      increases  for specific  capital  expenditures.  The process for receiving
      decisions on advice  letters is less involved  than for GRC  applications.
      Decisions  by the CPUC on advice  letters have been timely and much faster
      compared to GRC applications.  In June 2002, the CPUC authorized increased
      rates for our  Bakersfield  district of $800,000  on an annual  basis.  In
      April 2003, the CPUC  authorized  increased  rates of $1.8 million.  These
      increases  are  for  the  new  Bakersfield  treatment  plant  that  became
      operational in the second quarter of 2003. We expect to make an additional
      advice letter  application in the second half of 2003 for  Bakersfield for
      approximately  $4  million.   These  rate  increases  reflect   additional
      expenditures  related to the new treatment plant with a total project cost
      of approximately $49 million.

      Other  rate  increases  - The City of  Hawthorne  granted an  increase  of
      $200,000  effective  July 2003.  This  arrangement  is not governed by the
      CPUC.

Legislative Initiative

      Regulatory   delays  in  obtaining  GRC  decisions  have  been  costly  to
      California regulated water utilities. In recent years, we have experienced
      significant  revenue losses due to regulatory delays. We normally file our
      general  rate case  applications  in July.  The  CPUC's  stated  rate case
      processing  plan provides for a decision  within ten months.  In the past,
      when decisions were not issued in a timely manner, we lost revenue and did
      not recover costs during the period the decisions were delayed.

      Assembly Bill 2838 became  effective on January 1, 2003. It is designed to
      preserve the cash flow of regulated water  utilities by providing  interim
      rate relief if the CPUC has not issued a decision for a requested GRC rate
      increase within its established ten month processing  period.  The interim
      rate relief is subject to  adjustments  based on the CPUC's final decision
      in the GRC  proceeding.  For the six months ended June 30, 2003,  Assembly
      Bill 2838 did not have an impact on us in granting  interim  rate  relief.
      The CPUC  interpreted  the  provisions  of the  bill to apply  only to GRC
      applications subsequent to January 1, 2003 and the CPUC is reviewing their
      internal processing period.


LIQUIDITY

Short-term and Long-term Debt

      Short-term  bank  borrowings  were   $50,058,000  at  June  30,  2003  and
      $36,379,000  at December 31,  2002.  We have a $55 million  agreement  for
      California Water Service Company,  which expires in April 2005. The amount
      is reduced to $45 million after


                                       23


      December 31, 2003.  An amendment  was executed  which  revised the date of
      reduction  from June 30, 2003 to December 31, 2003.  The  agreement  has a
      30-day  out-of-debt  compliance  period that must be met by  December  31,
      2004. A $10 million credit  facility  exists for California  Water Service
      Group,  CWS Utility  Services and New Mexico Water  Service  Company.  The
      agreement has a 30-day  out-of-debt  compliance period that must be met by
      December 31, 2003.  New Mexico  Water  Service  Company has a $2.9 million
      facility  that was  renewed in January  2003 and expires May 2004 and does
      not  have an  out-of-debt  compliance  period.  Washington  Water  Service
      Company has a $0.1 million credit facility that is currently unused.

      We initiated a program in 2002 to  refinance a portion of our  outstanding
      first mortgage  bonds.  This program has been continued in 2003. On May 1,
      2003, we issued $10 million,  5.54%, 20-year series I Senior Notes and $10
      million,  5.44%, 15 year series J Senior Notes.  Both notes are unsecured.
      The proceeds from these  borrowings  were used to redeem EE First Mortgage
      bonds that had an interest rate of 7.9%. The principal,  call premiums and
      transaction  costs were  approximately  $20 million.  We will  continue to
      pursue refinancing  opportunities when economic  conditions are favorable.
      The entire  refinancing  program is expected to impact  approximately $100
      million of debt and is expected to save  approximately  $1.8 million on an
      annual basis.

Debt Credit Ratings

     California  Water  Service  Company is rated by Moody's  Investors  Service
     ("Moodys")  and Standard & Poor's  ("S&P").  The rating by Moodys is A1 and
     S&P is A+. The ratings were  unchanged  from the revised  ratings issued in
     the fourth quarter of 2002.

Shelf Registration Statement

      On July 11, 2003, we filed a shelf  registration  statement  providing for
      the  issuance  from time to time of up to  $120,000,000  in common  stock,
      preferred stock and/or debt securities, became effective. We may issue any
      of these types of securities until the amount registered is exhausted, and
      will add the net proceeds  from the sale of the  securities to our general
      funds  to be used  for  general  corporate  purposes,  which  may  include
      investment  in  subsidiaries,   working  capital,   capital  expenditures,
      repayment of  short-term  borrowings,  refinancing  of existing  long-term
      debt, acquisitions and other business opportunities.

      On August 4, 2003,  we  announced  the  issuance of  1,750,000  additional
      shares of common stock from the shelf registration statement. A prospectus
      supplement and  prospectus  were filed with the SEC under rule 424 (b) (2)
      on August 5,  2003.  The shares  were sold at $26.25  per  share.  The net
      proceeds to us were  approximately  $44 million  and the  transaction  was
      closed on  August 7,  2003.  The  funds  were used to pay down  short-term
      borrowings and to invest in short-term  money market  instruments  pending
      their  use for  general  corporate  purposes.  Additional  information  is
      incorporated  by  reference  to a Form 8-K filed on August 6, 2003.  After
      issuance of the 1,750,000 shares,  there remains $74,062,500 in securities
      under the shelf registration, which are available for future issuance.

Dividends, Book Value and Share Holders

      The second quarter  common  dividend was paid on May 16, 2003, at $0.28125
      per share compared to a quarterly  dividend in 2002 of $0.28. This was our
      234th consecutive quarterly dividend.  Annualized,  the 2003 dividend rate
      is  $1.125  per  common  share  compared  to $1.12  in 2002.  Based on the
      12-month earnings per share at June 30, 2003, the dividend payout ratio is
      118% of net income.  For the full year 2002,  the payout  ratio was 90% of
      net income. On a long-term basis, our goal is to achieve a dividend payout
      ratio of about 60% of net income.

      At their July 23,  2003  meeting,  the Board  declared  the third  quarter
      dividend of $0.28125  payable August 15, 2003 to stockholders of record on
      August 1, 2003. This will be the 235th consecutive quarterly dividend.

      About 4% of the outstanding shares  participate in a reinvestment  program
      under  the  Company's  Dividend   Reinvestment  and  Stock  Purchase  Plan
      ("Plan"). Shares required for the dividend reinvestment and stock purchase
      option of the Plan were  purchased  on the open  market.  Shares  are also
      purchased on the open market to fulfill the  requirements of our sponsored
      Employee  Savings  Plan  (401K).  Purchases  for  this  plan are made on a
      biweekly basis.

      Book value per common share was $12.81 at June 30, 2003 compared to $13.12
      at December 31, 2002.

      We have approximately 4,200 stockholders of record of our common stock.

Utility Plant

      During the six months ended June 30, 2003,  capital  expenditures  totaled
      $42.3 million.  $32.2 million was from company  funded  projects and $10.1
      was  from  of  third  party  funded  projects.  The  2003  Company  funded
      construction budget is $51.7 million.  Third party funded projects are not
      determined by us and,  therefore,  we are unable to estimate the amount of
      such projects for 2003.

      At June 30, 2003, construction work in progress was $73.3 million compared
      to $48.6 million at December 31, 2002. Work in progress  includes projects
      that are under  construction,  but not yet complete and in service. A main
      reason for the increase in work in progress is the $49.5 million  expended
      to date on the  Northeast  Bakersfield  Treatment  Plant.  This  amount is
      included in work in progress at June 30, 2003. This project is the largest
      construction  project  ever  undertaken  by  the  Company.  The  Northeast
      Bakersfield Treatment Plant began service to customers in May 2003.

WATER SUPPLY

      Based  on  information  from  water  management  agencies  and  internally
      developed  data,  we believe that our various  sources of water supply are
      sufficient  to  meet  customer  demand  for  the  remainder  of the  year.
      Historically,  about half of the water source is purchased  from wholesale
      suppliers  with the other half  pumped  from  underground  wells.  A small
      portion is developed through three local surface treatment plants.


                                       25


      To safeguard our water supply and facilities,  we have heightened security
      at our facilities and taken added safety precautions for our employees and
      the  water we  deliver  to our  customers.  While  we do not  make  public
      comments on our security  programs,  we have been in contact with federal,
      state and local law  enforcement  agencies to coordinate and improve water
      delivery systems security.  We have assigned a high priority to completing
      work  necessary  to  comply  with  new  Environmental   Protection  Agency
      requirements   concerning  security  of  water  facilities.   This  effort
      encompasses all of our district operations.


ACQUISITIONS

Rio Grande Utility Corporation

      On July 1, 2002, after receiving state regulatory  commission approval, we
      acquired  certain  assets of Rio Grande Utility  Corporation  (Rio Grande)
      through New Mexico Water.  The purchase  included the water and wastewater
      assets of Rio  Grande,  which  serves  2,400  water  and 1,700  wastewater
      customers about 30 miles south of Albuquerque. The purchase price was $2.3
      million in cash, plus assumption of $3.1 million in outstanding debt. Rate
      base for the system is approximately $5.4 million.  Revenues for 2002 were
      $1.6 million.

      The Rio  Grande  purchase  price was  allocated  to the fair  value of net
      assets  acquired,  including  utility  plant,  water  rights  and  assumed
      liabilities.  The  allocation  of fair  value  is  based  on  management's
      estimate of the fair value for purchase accounting purposes at the date of
      acquisition.  Our results of operations for the  three-month and six-month
      periods  ended June 30, 2003 include the  operating  results of New Mexico
      Water. These were not material to the Company.

Kaanapali Water Corporation

      On April 30, 2003,  we acquired the  Kaanapali  Water  Corporation  for an
      initial  payment of $7.5 million in cash. In July 2003, the purchase price
      was  adjusted  due  to  adjustments  in  rate  base  for  deferred  taxes.
      Approximately  $1.5 million was refunded to the Company resulting in a net
      purchase price $6.0 million.  The purchase price was allocated to the fair
      value of net assets  acquired,  including  utility  plant,  water  rights,
      receivables and assumed liabilities. The allocation of fair value is based
      on  management's  estimate  of the  fair  value  for  purchase  accounting
      purposes at the date of  acquisition  and is subject to adjustments as new
      information is available up to one year after the acquisition  date. After
      completing the acquisition,  the entity's name was changed to Hawaii Water
      Service Company,  Inc. Hawaii Water provides water utility services to 500
      customers in Maui,  Hawaii. It had 2002 revenues of $3.0 million,  and has
      net plant excluding contributions in aid of constructions of approximately
      $5.7  million  and  current  assets of $0.3  million.  The  Hawaii  Public
      Utilities  Commission ("HPUC") approved the acquisition in March 2003. The
      final  purchase  price  will  be  determined  after  certain  events  have
      occurred, principally the resolution of determining rate base after filing
      for a general rate case with the HPUC.  At that time,  the purchase  price
      could be adjusted.  Preliminary  estimates of the amount of adjustment are
      between 0 and 5% of the purchase price.

National Utilities Corporation

      In June 2002,  NMWSC signed an agreement  to purchase  National  Utilities
      Corporation and related  parties for  approximately  $1,100,000.  National
      Utilities  serves 700 water customers  located  adjacent to the Rio Grande
      water  system and another 900 water  customers  located


                                       26


      150 miles south of  Albuquerque,  New Mexico.  The  purchase  will entitle
      NMWSC to purchase up to 2,000  acre-feet of water annually as required for
      its operations.  The purchase is subject to the approval of the New Mexico
      Public Regulation Commission. Regulatory approval is expected in the third
      quarter of 2003 and the  transaction  is  expected  to close in the fourth
      quarter.

      National  Utilities  had 2001  revenue  of  $575,000  and total  assets of
      $1,425,000.  Its net  utility  plant in service at  December  31, 2001 was
      $1,143,000.

Item 3.

QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

      We do not hold,  trade in or issue  derivative  financial  instruments and
      therefore are not exposed to risks these instruments  present.  Our market
      risk to interest  rate  exposure is limited  because the cost of long-term
      financing and short-term  bank  borrowings,  including  interest costs, is
      covered in consumer water rates as approved by the commissions.  We do not
      have  foreign  operations;  therefore,  we do not have a foreign  currency
      exchange risk.  Our business is sensitive to commodity  prices and is most
      affected by changes in purchased water and purchased power costs.

      Historically,  the commission's  balancing  account or offsetable  expense
      procedures  allowed for increases in purchased  water and purchased  power
      costs to be passed on to  consumers.  Over 95% of our net  income and cash
      flows come from California  operations;  therefore the CPUC actions have a
      significant  impact on our  business.  See Item 2, Expense  Balancing  and
      Memorandum Accounts and Regulatory Matters.


Item 4.

CONTROLS AND PROCEDURES

      (a) Evaluation of Disclosure Controls and Procedures

      We  carried  out an  evaluation,  under  the  supervision  of and with the
      participation  of our  management,  including our principal  executive and
      principal  financial  officer,  of the  effectiveness  of the  design  and
      operation of our  disclosure  controls and procedures as of the end of the
      period by this report,  pursuant to Rule  13a-15(b)  under the  Securities
      Exchange Act of 1934. Based on their review of our disclosure controls and
      procedures,  the  principal  executive  officer  and  principal  financial
      officer have  concluded  that our  disclosure  controls and procedures are
      effective in timely alerting us to material  information  that is required
      to be included in periodic SEC filings.


                                       27


      (b) Changes to Internal controls

      There were no changes in our internal  controls over  financial  reporting
      that  occurred  during  our  last  fiscal  quarter  that  have  materially
      affected, or are reasonably likely to materially affect, such controls.


PART II  OTHER INFORMATION

Item 1.

LEGAL PROCEEDINGS

(a)      In March 2003, we were served with a lawsuit in state court,  as one of
         several  defendants,  for damages and  injuries  related  from  alleged
         contamination in our drinking water supply in the Marysville  district.
         The suit did not  specify  a dollar  amount.  In June  2003,  all other
         defendants,  who were governmental  entities,  were dismissed,  and the
         plaintiff was granted leave to amend his complaint against us. Based on
         plaintiff's previously filed complaints, we doubt the amended complaint
         will allege any facts under which we may be held  liable.  We intend to
         vigorously  defend the suit. In 2000 and 2002,  the same  plaintiffs in
         this action  brought  suits  against us in federal  court with  similar
         allegations concerning drinking water supply contamination. All federal
         claims were  dismissed  with  prejudice;  however,  the  Federal  Court
         refused to hear the state claims.  Our insurance  carrier is paying for
         legal  defense  costs,  and we believe that our  insurance  policy will
         cover all costs related to this matter.


(b)      Cal Water is required to report each water  system  acquisition  to the
         CPUC and obtain CPUC  authorization  before charging rates. In February
         2003,  the CPUC`s Office of Ratepayer  Advocates  recommended  that the
         Company be fined up to  $9,600,000  and refund  $470,000 for failure to
         report  and  obtain  CPUC  authorizations  on  two  acquisitions.   One
         acquisition  was  completed  on March 12, 1997 prior to adoption of the
         reporting  requirement  by the CPUC;  the other was  inadvertently  not
         reported. Cal Water purchased the two water systems (Indian Springs and
         Country  Meadows),   which  serve  283  customers,   for  approximately
         $140,000.  The staff's  recommendation  does not challenge the level of
         service  provided or amounts charged for water service to the customers
         but our failure to obtain  authorization  to charge  rates set forth in
         the purchase  agreements and our failure to report the  acquisitions to
         the  CPUC  in  accordance  with a  previously  executed  memorandum  of
         understanding.  Cal Water and the Office of Ratepayer  Advocates  (ORA)
         have  filed  their   briefs  in  the  matter  and  are   awaiting   the
         Administrative  Law Judge's issuance of a proposed  ruling.  We believe
         that ORA's recommendation is extraordinarily  harsh given the nature of
         the infractions and that any penalty will be substantially reduced when
         this matter is considered by the full CPUC.


                                       28


         On May 7,  2002,  the Cal  Water  filed  Advice  Letters  1514 and 1515
         notifying  the  CPUC  of its  acquisition  of  the  water  systems  and
         requesting  authorization  to charge the rates  filed and  include  the
         Indian  Springs  and  Country  Meadows  water  systems  in its  Salinas
         District. Additionally, on June 26, 2002, Cal Water filed Advice Letter
         1517 notifying the CPUC of its acquisition of the Olcese Water District
         water  system and to include  this system in its Salinas  district.  On
         July 10, 2003, the CPUC issued  Resolution  W-4390.  In this resolution
         the Commission  staff raised the issue of the legality of the contracts
         entered  into by Cal Water to acquire  the Indian  Springs  and Country
         Meadows  water  systems  and  whether  Cal Water  complied  with  legal
         requirements  prior to  charging  rates to the  Olcese  Water  District
         customers.  The resolution grants the Company's request to consult with
         the CPUC Water  Division  with the goal of resolving  issues within 120
         days, at which time,  the CPUC will then consider if additional  action
         is warranted.  We are working with Water  Division to  reconstruct  the
         contracts.  At this time, we cannot  estimate the amount of the penalty
         or the timing of the resolution of these issues.
