                         CALIFORNIA WATER SERVICE GROUP
              Notes to Condensed Consolidated Financial Statements
                               September 30, 2004


Note 1.  Organization and Operations

         California  Water Service Group (the Company) is a holding company that
         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  Company  (Washington  Water),  New Mexico Water Service
         Company  (New Mexico  Water) and Hawaii  Water  Service  Company,  Inc.
         (Hawaii Water) provide  regulated  utility services under the rules and
         regulations  of their  respective  state's  regulatory  commission.  In
         addition, these entities and CWS Utility Services provide non-regulated
         water utility and 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  covered.  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,  2003,  included in its Form 10-K as filed
         with the Securities and Exchange Commission on March 15, 2004.


Note 3.  Stock-based Compensation

         The Company has a  stockholder-approved  Long-Term  Incentive Plan that
         allows granting of non-qualified 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.  As permitted by SFAS No. 123, the Company applies  Accounting
         Principles  Board  Opinion  No.  25,  "Accounting  for Stock  Issued to
         Employees," for its plan. All outstanding options had an exercise price
         equal  to  the  market  price  on  the  date  they  were  granted.   No
         compensation expense was recorded for the three- and nine-month periods
         ended September 30, 2004 and 2003 related to stock options.  No options
         were granted during these periods.




                                       8

         The table below  illustrates  the effect on net income and earnings per
         share  as if  the  Company  had  applied  the  fair  value  recognition

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  rainfall
         curtail water usage and sales.


Note 5.  Earnings Per Share Calculations

         The  computations  of basic and  diluted  earnings  per share are noted

Note 6.  Pension Plan and Other Postretirement Benefits

         The Company  provides a  qualified,  defined-benefit,  non-contributory
         pension plan for substantially all employees.  The Company makes annual
         contributions  to fund the amounts  accrued for the  qualified  pension
         plan.   The  Company  also   maintains   an  unfunded,   non-qualified,
         supplemental  executive  retirement  plan.  The  costs of the plans are
         charged to expense and utility plant.

         The Company offers medical,  dental, vision and life insurance benefits
         for  retirees  and  their  spouses  and  dependents.  Participants  are
         required to pay a premium, which offsets a portion of the cost.

         Payments   by  the   Company   related  to  pension   plans  and  other
         postretirement  benefits  were  $3,767,000  for the three  months ended
         September 30, 2004, and $9,808,000 for the nine months ended  September
         30, 2004. The Company plans to fund $12,600,000 in 2004, an increase of
         $1,100,000 from the amount reported in the previous  quarter.  Payments
         may be further  adjusted prior to December 2004 upon receipt of revised
         calculations from the Company's actuary.


                                       11

         30, 2004, the Company had a regulatory  asset of $8,175,000  related to
         postretirement  benefits,  which is  expected to be  recovered  through
         future customer rates. The regulatory asset incorporates a reduction of
         $604,000  due  to  the  Medicare  Prescription  Drug,  Improvement  and
         Modernization Act of 2003. See Note 9, New Accounting Standards.


Note 7.  Financing

         On June 24, 2004, the Company announced the sale of 1,250,000 shares of
         common stock. A prospectus  supplement  and prospectus  were filed with
         the SEC under  rule 424 (b) (2) on that date.  The shares  were sold at
         $27.25   per  share.   The   underwriters   exercised   part  of  their
         over-allotment  option, after which the additional common shares issued
         totaled  1,409,700  shares.  The net proceeds were  $36,800,000 and the
         transaction  was  closed on June 29,  2004.  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.  After
         issuance of these shares, there remains $35,648,175 in securities under
         the shelf registration, which are available for future issuance.


Note 8.  CPUC Decision Related to Failure to Report Acquisitions

         On July 8, 2004,  the California  Public  Utilities  Commission  (CPUC)
         issued a final decision regarding the Company's failure to report three
         small  acquisitions.  The Company was  assessed a fine of $75,000 and a
         reduction of 50 basis points (0.5%) in the allowed return on equity for
         its Salinas  district,  the  district  that  includes  two of the three
         acquisitions.  The time  frame for the  return on equity  reduction  is
         expected  to be  one  year.  The  Office  of  Ratepayer  Advocates  had
         recommended  a fine of $9.6 million and refund of $0.5  million,  which
         the CPUC rejected.  Prior to this decision, the Company had filed for a
         general  rate  increase  in its  Salinas  district,  which the CPUC was
         holding pending the resolution of this matter.  With the final decision
         on this matter,  a rate increase for the Salinas  district was approved
         in July 2004 that will increase  annual  revenues by an estimated  $1.1
         million,  after adjustment for the reduction in allowed rate of return.
         The $75,000 fine was recorded as an expense in the second quarter.  The
         increase in revenue is recorded  when billed to  customers,  consistent
         with the Company's revenue recognition practices.


Note 9.  New Accounting Standards

         In December  2003,  the  Financial  Accounting  Standards  Board (FASB)
         issued  Interpretation  No. 46R,  "Consolidation  of Variable  Interest
         Entities,"  which  amended  Interpretation  No. 46,  "Consolidation  of
         Variable Interest Entities." The revision exempted certain entities and
         modified the  effective  dates of  Interpretation  No. 46. The original
         guidance  issued under  Interpretation  No. 46 in January 2003 is still


                                       13


         applicable.  Interpretation  No. 46 and  Interpretation No. 46R provide
         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.
         46R was effective  March 31, 2004. The adoption of  Interpretation  No.
         46R did  not  impact  the  Company's  financial  position,  results  of
         operations or cash flows.

         In December  2003, the FASB issued  Statements of Financial  Accounting
         Standards  (SFAS)  No. 132  (revised),  "Employers'  Disclosures  about
         Pensions  and Other  Postretirement  Benefits  - An  Amendment  of FASB
         Statements  No. 87, 88, and 106," which  changed  certain  disclosures.
         SFAS No. 132  (revised)  was  effective  for fiscal  years ending after
         December 15,  2003,  and is effective  for  interim-period  disclosures
         beginning  after  December  15,  2003.  As  the  revision   relates  to
         disclosure requirements, the adoption of SFAS No. 132 (revised) did not
         impact the Company's financial position,  results of operations or cash
         flows.

         In May 2004,  the FASB  issued  FASB Staff  Position  (FSP) No.  106-2,
         "Accounting  and  Disclosure   Requirements  Related  to  the  Medicare
         Prescription Drug,  Improvement and Modernization Act of 2003." FSP No.
         106-2 is  effective  for the first  quarter  after June 15,  2004,  and
         replaces  FSP No.  106-1.  FSP 106-1 was  effective  for the  Company's
         consolidated financial statements for the year ended December 31, 2003.
         The  Company has  determined  its  retiree  health plan is  actuarially
         equivalent  and would  qualify for the subsidy.  Because the Company is
         regulated,  FSP 106-2 did not have an impact to the income statement or
         cash flows.  The  adjustment  for FSP 106-2  impacts the balance  sheet
         only,  decreasing  liabilities  and  assets by  $604,000.  The  Company
         believes it will be  eligible  for the  subsidy  starting in 2006.  The
         Company  has not yet decided on whether any or a portion of the subsidy
         will impact premiums charged to retirees, therefore this adjustment may
         change once a decision has been made.

Item 2

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

FORWARD LOOKING STATEMENTS

         This quarterly report contains  forward-looking  statements  within the
         meaning established by the Private Securities  Litigation Reform Act of
         1995 (Act).  The  forward-looking  statements  are  intended to qualify
         under  provisions  of the  federal  securities  laws for "safe  harbor"
         treatment established by the Act. 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.
         Such words as expects,  intends, plans, believes,  estimates,  assumes,
         anticipates,  projects, predicts, forecasts or variations of such words
         or  similar  expressions  are  intended  to  identify   forward-looking
         statements. The forward-looking statements are not guarantees of future
         performance.   They  are   subject  to   uncertainty   and  changes  in
         circumstances.   Actual  results  may  vary  materially  from  what  is
         contained  in a  forward-looking  statement.  Factors  that may cause a
         result 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; the ability to satisfy
         requirements  related  to  Sarbanes  Oxley  Act  section  404 and other
         regulations  on  internal  controls;   condemnation  actions  taken  by
         governmental  entities;  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; acquisitions and the ability
         to  successfully   integrate   acquired   companies;   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 the 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 current or future debt that could increase  financing
         costs or affect the  ability to borrow,  make  payments  on debt or pay
         dividends;  and, other risks and unforeseen  events.  When  considering
         forward-looking   statements,  the  reader  should  keep  in  mind  the
         cautionary  statements included in this paragraph.  The Company assumes
         no obligation to provide public updates of forward-looking statements.


CRITICAL ACCOUNTING POLICIES

         The  Company  maintains  its  accounting  records  in  accordance  with
         accounting  principles  generally  accepted  in the  United  States  of
         America  and as  directed by the  regulatory  commissions  to which the
         Company is  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


                                       15


         that the  following  accounting  policies  are  critical  because  they
         involve a higher  degree of  complexity  and  judgment,  and can have a
         material impact on the results of operations and financial condition.

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 September 30, 2004, the
         unbilled  revenue amount was  $12,906,000 and at December 31, 2003, the
         amount was $8,522,000.  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 $2,102,000 at September 30, 2004, and $2,127,000
         at December 31, 2003.  This liability is included in "accrued  expenses
         and other liabilities" on the balance sheet.

Expense Balancing and Memorandum Accounts
- -----------------------------------------

         Expense  balancing   accounts  and  memorandum   accounts   (offsetable
         expenses)  represent  recoverable  costs  incurred,  but not  billed to
         customers.  The  amounts  included  in these  accounts  relate  to rate
         increases  charged by suppliers of purchased  water and purchased power
         and increases in pump taxes, and only apply to the Company's California
         regulated operations.  The Company does not record expense balancing or
         memorandum  accounts in its financial  statements  as revenue,  or as a
         receivable,  until the CPUC has authorized recovery of the higher costs
         and customers  have been billed.  Therefore,  a timing  difference  may
         occur between when costs are incurred and the  associated  revenues are
         recognized.  The  balancing  and  memorandum  accounts are only used to
         track the cost variances outside of the financial statements.  The cost
         variances,  which are beyond the Company's control,  are referred to as
         "offsetable  expenses"  because  under certain  circumstances  they are
         recoverable  from customers in future offset rate increases (or, in the
         case of expense  reductions,  are credited to  customers).  The amounts
         requested may not be ultimately collected through rates, as amounts may
         be disallowed during the review process or subject to an earnings test.
         While the adjustments would not impact previously recorded amounts, the
         adjustments may change future  earnings and cash flows.  See Regulatory
         Matters for net balances of expense balancing and memorandum accounts.


                                       16


Regulated Utility Accounting
- ----------------------------

         Because the Company operates extensively in a regulated business, it is
         subject to the provisions of 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 the Company's operations were no
         longer  subject to the  provisions of SFAS No. 71, it 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 the
         Company's  assets were not recoverable in customer  rates,  the Company
         would be required to determine  if it had suffered an asset  impairment
         that would  require a write-down in the assets'  valuation.  There have
         been no such asset impairments as of September 30, 2004.

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  differing  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.  Management 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 at September
         30, 2004.

Pension Benefits
- ----------------

         The Company incurs costs associated with its 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  from independent  advisors and actuaries.  The Company
         uses an  investment  advisor to provide  advice in managing  the plan's
         investments.  Management  anticipates  that any increase in funding for
         the  pension and  postretirement  health  care  benefits  plans will be
         recovered in future customer rates.

RESULTS OF THIRD QUARTER 2004 OPERATIONS COMPARED TO THIRD QUARTER
2003 OPERATIONS

Summary
- -------

         Third  quarter  net income  was  $10,789,000,  equivalent  to $0.59 per
         common share on a diluted  basis,  compared to net income of $8,587,000
         or $0.53 per share on a diluted basis in the third quarter of 2003. The
         primary driver was an increase in rates.  Partially  offsetting revenue
         increases  were cost  increases  for  purchased  water,  income  taxes,
         depreciation and other expenses.  In addition,  more common shares were
         outstanding in 2004 than in 2003.

Operating Revenue
- -----------------

         Operating  revenue  increased  $8,907,000,  or 10%, to $97,104,000.  As
         disclosed in the  following  table,  the increase was due  primarily to
         increases in rates.  Weather impact was  unfavorable,  as  temperatures
         were  slightly  lower and decreased  usage  compared to the prior year.
         Rainfall was minor in both periods.

         The factors that affected the operating  revenue increase for the third
         quarter of 2004 are presented in the following table:

         Rate increases                                             $ 9,922,000
         Usage by new customers                                       1,318,000
         Decrease in usage by existing customers                     (2,333,000)
                                                                    -----------
              Net operating revenue increase                        $ 8,907,000

Total Operating Expenses
- ------------------------

         Total  operating  expenses were  $82,606,000 for the three months ended
         September  30, 2004, up 9% over the  $75,678,000  recorded for the same
         period in 2003.


                                       18



         Water production  expense consists of purchased water,  purchased power
         and pump taxes. It represents the largest  component of total operating
         expenses, accounting for approximately 49% of total operating expenses.
         Water production expenses increased 3% compared to last year.

         For California operations, sources of water as a percent of total water
         production are listed on the following table:

                                        ===========   ===========   ===========

         Purchased  water cost  increased  principally  due to higher  wholesale
         water  rates in several  districts.  Included  in  purchased  water are
         credits  received  from certain  wholesale  suppliers and sale of water
         rights.  The amounts of the credits were $366,000 and $739,000 for 2004
         and 2003,  respectively.  Purchased  power decreased due principally to
         lower  rates.  Pump  taxes  increased  primarily  due  to  higher  well
         production  in the Los  Altos  district,  where  pump tax rates are the
         highest of all of the Company's districts.

         Payroll charged to operations  expense increased  $571,000 or 7%. Wages
         for union employees  increased 1.5% effective January 1, 2004.  Overall
         payroll costs (expensed and capitalized)  increased 6% due to increases
         in the number of employees and higher wage rates.  Employee and retiree
         medical costs increased  $528,000 or 32%. Workers'  compensation  costs
         increased  $425,000 or 128%.  At  September  30,  2004,  there were 830
         employees and at September 30, 2003, there were 814 employees.

         Other  areas  of  major  expense  increases  were:   outside  services,
         principally  related to compliance with the internal control provisions
         of Sarbanes  Oxley  ($467,000);  increases for fees payable to the CPUC
         ($160,000),  which are calculated on a percentage of revenue; increases


                                       19


         for  bad  debts  ($161,000);   increases  related  to  the  Bakersfield
         Treatment  Plant  operations  ($124,000)  and  increases  for  training
         ($103,000).

         Maintenance expense increased  $468,000,  or 15%, for the quarter ended
         September 30, 2004, primarily for mains and service lines. Depreciation
         and  amortization  expense  increased  $688,000  or 12% because of 2003
         capital  expenditures.  A major component of the  depreciation  expense
         increase  relates  to the  Bakersfield  Treatment  Plant,  which  began
         operations  in the second  quarter of 2003.  Depreciation  of the plant
         began January 2004,  consistent with the Company's accounting policies,
         and added  $484,000  to  depreciation  expense in the third  quarter of
         2004.

         Federal and state income taxes  increased  $1,463,000 or 26% due to the
         increase in taxable income.  The effective tax rate was 40% and 39% for
         the third quarters of 2004 and 2003, respectively.

Other Income and Expense
- ------------------------

         Other  income was $656,000 for the quarter  ended  September  30, 2004,
         compared to $647,000  in the prior year,  an increase of $9,000.  Gains
         from property sales were minor in both periods.

Interest Expense
- ----------------

         Total  interest  expense  decreased  $214,000 or 5%. The  decrease  was
         principally due to lower short-term borrowings.


RESULTS OF OPERATIONS FOR THE NINE MONTHS ENDED SEPTEMBER 2004 COMPARED TO THE
NINE MONTHS ENDED SEPTEMBER 2003

Summary
- -------

         Net income for the  nine-month  period ended  September  30, 2004,  was
         $22,289,000,  equivalent to $1.27 per common share on a diluted  basis,
         compared to net income of  $12,404,000  or $0.79 per share on a diluted
         basis,  for the nine  months  ended  September  30,  2003.  The primary
         drivers  were  increases  in rates  and  favorable  weather  conditions
         occurring in the second quarter.  Partially  offsetting the increase in
         revenues  were  cost  increases  for  purchased  water,  income  taxes,
         depreciation  and  other  expenses.  In  addition,   more  shares  were
         outstanding in 2004 than in 2003.

Operating Revenue
- -----------------

         Operating  revenue  increased  $38,687,000 or 19% to  $246,189,000.  As
         disclosed in the following  table, the increase was due to increases in
         rates and  increases in water usage.  Weather  impact was  favorable as
         rainfall was much lower than in the prior year, primarily in the second
         quarter.  Temperatures were  approximately the same. The lower rainfall
         increased  water  usage by 8% above the prior  year,  with the  largest
         monthly  increase  (30%)  in  April.  The  factors  that  affected  the
         operating revenue increase are presented in the following table:

         Usage by new customers includes $970,000 related to Hawaii Water, whose
         operations  were acquired in May 2003, and includes  $1,016,000 for the
         City of Commerce, for which the lease arrangement began in July 2003.

Total Operating Expenses
- ------------------------

         Total operating  expenses were  $212,217,000  for the nine months ended
         September 30, 2004, an increase of 15% over the  $184,809,000  recorded
         for the same period in 2003.

         Water production  expense consists of purchased water,  purchased power
         and pump taxes. It represents the largest  component of total operating
         expenses, accounting for approximately 45% of total operating expenses.
         Water production expenses increased 13% compared to last year.

         For California operations, sources of water as a percent of total water
         production are listed on the following table:

         Purchased  water cost increased due to higher  wholesale water rates in
         several districts and increased purchases of purchased water.  Included
         in  purchased  water  costs was an  additional  expense of  $868,000 to
         revise the  settlement  cost to  $1,599,000  related to the  previously
         reported meter  malfunction  at the wholesale  supplier in the Stockton
         district.  The estimate was revised  after  completion  of a study by a
         third party and negotiation of a settlement  with all parties.  For the
         nine months ended  September  30, 2003,  expenses  related to the meter
         malfunction  were  approximately  $487,000.  Also included in purchased
         water are credits received from certain wholesale suppliers and sale of
         water rights. The amounts of the credits were $2,942,000 and $2,717,000
         for 2004 and 2003,  respectively.  Purchased  power  decreased due to a
         decrease in electricity  rates.  Pump taxes increased  primarily due to
         higher well production in the Los Altos district,  where pump tax rates
         are the highest of all of the Company's districts.

         Payroll charged to operations expense increased $2,000,000 or 8%. Wages
         for union employees  increased 1.5% effective January 1, 2004.  Overall
         payroll costs (expensed and capitalized)  increased 5% due to increases
         in the number of employees and higher wage rates.  Employee and retiree
         medical costs increased $1,162,000 or 22%. Workers'  compensation costs
         increased  $815,000  or 88%.  At  September  30,  2004,  there were 830
         employees and at September 30, 2003, there were 814 employees.

         Other areas of major  expense  increases  were:  increases  for outside
         services,  principally  related to compliance with the internal control
         provisions of Sarbanes Oxley ($585,000);  increases for fees payable to
         the CPUC  ($516,000),  which are calculated on a percentage of revenue;
         increases  related  to  the  Bakersfield   Treatment  Plant  operations
         ($539,000), increases for bad debts ($169,000); increases for insurance
         ($287,000); and increases for training ($251,000).

         Maintenance  expense  increased  $365,000  or 4% for  the  nine  months
         primarily   due  to  repairs  to  service   lines.   Depreciation   and
         amortization  expense  increased  $2,129,000  or 12%  because  of  2003
         capital  expenditures.  A major component of the  depreciation  expense
         increase  relates  to the  Bakersfield  Treatment  Plant,  which  began
         operations  in the second  quarter of 2003.  Depreciation  of the plant
         began January 2004,  consistent with the Company's accounting policies,
         and added $1,451,000 to depreciation expense in 2004.

                                       22


         Federal and state income taxes increased $6,504,000,  or 78% due to the
         increase in taxable income.  The effective tax rate was 40% in 2004 and
         40% in 2003.

Other Income and Expense
- ------------------------

         Other income was  $1,780,000  for the nine months ended  September  30,
         2004,  compared  to  $3,327,000  for the first nine  months of 2003,  a
         decrease of $1,547,000. Gains from property sales for 2004 were minimal
         compared to gains of $1,535,000 in 2003.

Interest Expense
- ----------------

         Total interest expense decreased  $153,000 or 1%. This was due to lower
         short-term borrowings and lower interest expense on long-term debt as a
         result of refinancing a portion of the debt.  Partially  offsetting the
         decrease was a reduction in capitalized interest,  which is a credit to
         total  interest  expense.  Construction  work-in-progress  amounts were
         lower in the first  nine  months  of 2004  compared  to the first  nine
         months of 2003.


REGULATORY MATTERS

Rate Case Proceedings
- ---------------------

         Filings that were approved in 2003 were  disclosed in the  Management's
         Discussion  and Analysis  section of the annual report on Form 10-K for
         2003.  Filings approved in 2003 may impact 2004 revenues  incrementally
         as revenue is recorded based on billings to customers.

         Following are major filings approved in 2004 (through October 2004):
         --------------------------------------------------------------------

         In 2004,  Cal  Water  received  approval  from  the CPUC for step  rate
         increases of  $4,433,000 on an annual basis,  of which  $3,902,000  was
         effective in January 2004 and $531,000 was effective in April 2004.

         In February 2004, the CPUC authorized an advice letter for $718,000 for
         one district related to increase purchased water rates. The rate change
         was effective in February  2004 and will be collected  over the next 12
         months.

Expense Balancing and Memorandum Accounts
- -----------------------------------------

         The following  discussion  relates to changes in the Company's  expense
         balancing  memorandum  accounts (See "Expense  Balancing and Memorandum

         In May 2003,  Cal Water  received  approval from the CPUC to recover in
         rates a net $4,649,000,  which relate primarily to expenses incurred in
         2001. The net amounts remaining to be collected in rates as of December
         2003 was $2,760,000. At September, 2004, the net amounts remaining were
         $1,051,000,  which is  expected to be fully  recovered/refunded  by May
         2005.

         In May 2004,  Cal Water  received  approval  from the CPUC to refund in
         rates $1,515,000 which relates primarily to over collection of specific
         expenses  incurred over  multiple  years in the King City and Dominguez
         districts. At September 2004, the credit amounts remaining for the King
         City and  Dominguez  districts  were  $874,000  which is expected to be
         refunded by May 2005,  except for a minor  credit that will be refunded
         by May 2007.

         In June 2004, Cal Water  received  approval from the CPUC to recover in
         rates $394,000.  This amount relates primarily of recoverable  expenses
         incurred in 2001 for the  Salinas  district.  At  September  2004,  the
         amount  remaining  for the  Salinas  district  was  $313,000  which  is
         expected to be fully recovered by June 2006.

         In October 2004, Cal Water  received  approval from the CPUC to recover
         in  rates  a  net  $5,639,000.   These  amounts  relate   primarily  of
         recoverable  expenses  incurred  in 2002 and 2003.  These  amounts  are
         expected to be recovered/refunded by October 2006.

Pending Filings as of October 2004
- ----------------------------------

         Cal Water has pending  its 2004 GRC filing  covering 8  districts.  The
         amount requested is $26,500,000. The amount may change due to a variety
         of factors.  Over the past few years,  the amount  approved by the CPUC
         has been  substantially  less than the requested amount. The Company is
         unable to predict the timing and final amount of these  filings at this
         time.

         Cal Water is in the process of re-filing  advice  letters for balancing
         and memorandum  account  recovery for three  districts in the amount of
         $3,560,000.  It is expected the re-filing will be completed  within one
         month and CPUC approval will be received prior to April 2005.

         New  Mexico  Water  has filed for rate  increases  for its waste  water
         operations  and Hawaii Water has  submitted a rate filing for its water
         operations. When approved, these filings are not expected to materially
         affect the total Company  results.  We are unable to predict the timing


                                       24


         and final amount of these filings at this time. Washington Water is not
         planning to submit a rate filing in 2004.


LIQUIDITY

Short-term and Long-term Debt
- -----------------------------

         Short-term bank borrowings were $0 at September 30, 2004 and $6,454,000
         at December 31, 2003.  California Water Service Group has a $10,000,000
         credit  facility,  which includes  Washington  Water, New Mexico Water,
         Hawaii Water and CWS Utility  Services,  and had no borrowings  against
         the facility at September 30, 2004. Cal Water has a $45,000,000  credit
         facility and had no  borrowings  against the facility at September  30,
         2004. A $500,000  letter of credit is  outstanding  under the Cal Water
         facility,   which  reduces  amounts   available  for  borrowing.   Both
         agreements  have  a  requirement  for  balances  to  be  below  certain
         thresholds  for 30  consecutive  days each  calendar year (a clean down
         requirement)  and both  agreements  require  minimum ratings by defined
         credit agencies on Cal Water's senior,  long-term debt. The Company has
         met the clean down  requirements  for 2004 for both  agreements and has
         credit  ratings  meeting the  requirements.  At September 30, 2004, the
         Company was in compliance with the covenants of both facilities.

         In May 2004,  New Mexico Water  entered into a credit  agreement  which
         allows  borrowings  up to  $3,400,000.  The  term  is 16  months  until
         approval  has been  received  from  the New  Mexico  Public  Regulation
         Commission,  upon which the term will be ten years.  A request has been
         filed and is expected to be received in the fourth  quarter of 2004. At
         September 30, 2004, no amounts were borrowed against the agreement. The
         prior New Mexico Water credit agreement had borrowings of approximately
         $2,500,000,  which was paid and not  renewed.  Funds from  intercompany
         borrowings  with  California  Water  Service Group were used to pay the
         debt.

         There were no  additions  to long-term  debt in the  nine-month  period
         ended  September 30, 2004.  Principal  payments of $62,000 and $378,000
         were made during the three- and nine-month  periods ended September 30,
         2004, respectively.

         In September  2004, Cal Water received  authorization  from the CPUC on
         its Financing  filing  related to  $250,000,000  of additional  debt or
         equity  available for issuance  through the year 2009. This amount will
         be utilized on an  as-needed  basis.  The  balance  remaining  from the
         previous authorization does not carry over.


Debt Credit Ratings
- -------------------

         Cal Water's debt is rated A2 by Moody's Investors Service (Moody's) and
         A+ by Standard & Poor's (S&P).  The rating from Moody's was  downgraded
         in February  2004 from A1 to A2. The last rating change from S&P was in
         the fourth  quarter of 2002.  There  have not been  further  changes by
         Moody's or S&P as of the filing date of this Form 10-Q.


                                       25


Common Stock Issuance and Treasury Stock
- ----------------------------------------

         On June 24, 2004, the Company announced the sale of 1,250,000 shares of
         common stock. A prospectus  supplement  and prospectus  were filed with
         the SEC under  rule 424 (b) (2) on that date.  The shares  were sold at
         $27.25   per  share.   The   underwriters   exercised   part  of  their
         over-allotment  option, after which the additional common shares issued
         totaled 1,409,700 shares.  The proceeds net of expenses of the offering
         were  $36,800,000  and the  transaction  was  closed on June 29,  2004.
         Initially, 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.  After  issuance of these  shares,  there
         remains $35,648,175 in securities under the shelf  registration,  which
         are available for future issuance.

         No treasury stock was issued or redeemed during 2004 or 2003.

Dividends, Book Value and Shareholders
- --------------------------------------

         The third quarter common stock dividend was paid on August 20, 2004, at
         $0.2825  per  share,  compared  to a  quarterly  dividend  in  2003  of
         $0.28125.  This was the Company's 239th consecutive quarterly dividend.
         Annualized,  the 2004 dividend rate is $1.13 per common share, compared
         to  $1.125  in  2003.  Based  on the  12-month  earnings  per  share at
         September 30, 2004, the dividend payout ratio is 67% of net income. For
         the full  year  2003,  the  payout  ratio was 93% of net  income.  On a
         long-term  basis, the goal is to achieve a dividend payout ratio of 60%
         of net income accomplished through future earnings growth.

         At its October 27, 2004 meeting,  the Board declared the fourth quarter
         dividend  of  $0.2825  per share,  payable on  November  19,  2004,  to
         stockholders  of record on  November  8,  2004.  This will be the 240th
         consecutive quarterly dividend.

Dividend Reinvestment and Stock Purchase Plan
- ---------------------------------------------

         The Company has a dividend  reinvestment and stock purchase plan called
         the  "Investor  Choice  Plan" and it is  administered  by its  transfer
         agent,  American  Stock  Transfer  and Trust  Company.  Under the plan,
         stockholders  may  reinvest  dividends to purchase  additional  Company
         common stock without  commission  fees.  The Plan also allows  existing
         stockholders and other interested  investors to purchase Company common
         stock through the transfer agent without  commission fees up to certain
         limits.  The  transfer  agent  purchases  shares on the open  market to
         provide shares for the Plan.

Transfer Agent
- --------------

         Effective  October 1, 2004,  the  Company  changed  transfer  agents to
         American  Stock  Transfer  and Trust  Company.  The agent  will  manage
         dividend payments,  provide a dividend  reinvestment and stock purchase
         plan, and other matters for the Company.  This change is expected to be
         transparent to the Company's stockholders.

2004 Financing Plan
- -------------------

         Proceeds from the issuance of additional common shares in June 2004 are
         expected  to provide  adequate  new capital for the balance of 2004 and
         may be supplemented  with short- term  borrowings as needed.  For 2005,
         the financing  plan includes  raising  $20,000,000 - $40,000,000 of new


                                       26


         capital and is expected to be accomplished  through  issuance of senior
         notes to institutional  investors.  The timing of the debt issuance for
         2005 has not been established. Beyond 2005, the plan is to fund capital
         needs through a relatively balanced approach between long-term debt and
         common stock equity.

Book Value and Stockholders of Record
- -------------------------------------

         Book value per common share was $15.75 at September 30, 2004,  compared
         to $14.44 at December 31, 2003.

         There are approximately  4,500 stockholders of record for the Company's
         common stock.

Utility Plant Expenditures
- --------------------------

         During the nine months ended September 30, 2004,  capital  expenditures
         totaled $49,076,000;  $35,969,000 was from company-funded  projects and
         $13,107,000   was  from  third   party   funded   projects.   The  2004
         company-funded  capital  expenditure budget is $65,800,000.  The actual
         amount  may vary due to timing of  payments  related  to  current  year
         projects and prior year projects. In addition, some projects planned to
         be completed in 2004 are expected to be completed in 2005.  The Company
         does not control third-party funded capital expenditures, and therefore
         it is unable to estimate the amount of such  projects for the full year
         of 2004.

         At September 30, 2004,  construction  work-in-progress  was $33,984,000
         compared to $13,770,000 at December 31, 2003. Work-in-progress includes
         projects  that are  under  construction,  but not yet  complete  and in
         service.


WATER SUPPLY

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

         To  safeguard  its  water  supply  and  facilities,   the  Company  has
         heightened  security  and has taken added  safety  precautions  for its
         employees and the water delivered to customers.  While the Company does
         not make public comments on its security programs,  management has been
         in contact with federal,  state and local law  enforcement  agencies to
         coordinate  and improve water  delivery  systems  security.  Management
         assigned a high  priority to completing  work  necessary to comply with
         new  Environmental  Protection  Agency  (EPA)  requirements  concerning
         security of water facilities.  In 2002, federal legislation was enacted
         that  resulted  in  new  regulations   concerning   security  of  water
         facilities,  including submitting  vulnerability  assessment studies to
         the federal  government.  The Company has  completed  and submitted all
         studies for all operations as required by this legislation.



                                       27


ACQUISITIONS

         On April 30, 2004, the Company  acquired the stock of National  Utility
         Company (NUC) and land from owners of NUC for approximately  $1,030,000
         in cash. The Company  retired NUC's stock and merged it into New Mexico
         Water  Service  Company.  Revenue  and net loss  for NUC for 2003  were
         $541,000  and   ($19,000),   respectively.   The   purchase   price  is
         approximately  equal to rate base and $30,000 of goodwill  was recorded
         in the transaction.


ACCOUNTING PRONOUNCEMENTS

Item 3.

QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

         The  Company  does not  hold,  trade in or issue  derivative  financial
         instruments  and  therefore  is not exposed to risks these  instruments
         present.  The 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.  The  Company  does  not  have  foreign
         operations;  therefore, does not have a foreign currency exchange risk.
         The business is sensitive to commodity  prices and is most  affected by
         changes in purchased water and purchased power costs.

         Historically,  the  CPUC's  balancing  account  or  offsetable  expense
         procedures allowed for increases in purchased water and purchased power
         costs to be passed on to  consumers.  A  significant  percentage of the
         Company's  net income and cash flows  comes from  California  regulated
         operations;  therefore  the CPUC's  actions  could impact the Company's
         ability to pass cost  increases  to its  customers  which  could have a
         significant impact on the business. See Item 2, Management's Discussion
         and Analysis of Financial Condition and Results of  Operations--Expense
         Balancing and Memorandum Accounts and Regulatory Matters.


Item 4.

CONTROLS AND PROCEDURES

         (a) Evaluation of Disclosure Controls and Procedures

         The Company  carried out an  evaluation,  under the  supervision of and
         with the participation of management, including the principal executive
         officer and principal  financial  officer,  of the effectiveness of the
         design  and  operation  of  the  Company's   disclosure   controls  and
         procedures as of the end of the period covered by this report, pursuant
         to Rule 13a-15(e) under the Securities  Exchange Act of 1934.  Based on
         their review of the Company's  disclosure controls and procedures,  the
         principal  executive  officer  and  principal  financial  officer  have
         concluded  that the Company's  disclosure  controls and  procedures are


                                       28


         functioning  effectively  to  provide  reasonable  assurance  that  the
         information  required  to be  disclosed  in  periodic  SEC  filings  is
         reported  within  the  time  periods  specified  by the SEC  rules  and
         regulations.

         (b) Changes to Internal controls

         There were no changes in the Company's  internal control over financial
         reporting  that  occurred  during  the last  fiscal  quarter  that have
         materially  affected,  or are reasonably  likely to materially  affect,
         such control.


PART II       OTHER INFORMATION


Item 1.

LEGAL PROCEEDINGS

         (a)   From time to time,  the Company has been involved in a variety of
               legal  proceedings.  For a description,  see the annual report on
               Form 10-K for the year ended  December 31, 2003.  During the nine
               months  ended   September  30,  2004,   there  were  no  material
               developments  with  respect  to  previously   disclosed  existing
               proceedings  and  no  new  material  proceedings  not  previously
               disclosed except as noted below.

         (b)   In  the  Company's  Selma   district,   the  City  Council  voted
               unanimously  on October 18, 2004,  not to adopt a  resolution  of
               necessity  and to abandon its efforts to purchase  the  Company's
               water system in Selma through condemnation procedures. Therefore,
               the Company will not take any further action on this matter.  The
               Company intends to improve working  relations and  communications
               with the City.
