              Notes to Consolidated Condensed Financial Statements

1.   Due to the seasonal nature of the water  business,  the results for interim
     periods may not be indicative of the results for a twelve-month period.

2.   The  interim  financial  information  is  unaudited.   In  the  opinion  of
     management,  the accompanying financial statements reflect all adjustments,
     which are  necessary  to provide a fair  statement  of the  results for the
     periods covered.  The adjustments consist of normal recurring  adjustments.
     Certain prior years' amounts have been  reclassified,  where necessary,  to
     conform to the current presentation.

3.   Basic  earnings per share is  calculated by dividing  income  available for
     common  stockholders  by the  weighted  average  number  of  common  shares
     outstanding during the period.  Diluted earnings per share is calculated by
     dividing income  available for common  stockholders by the weighted average
     number of common  shares  outstanding  plus  potentially  dilutive  shares.
     Income available for common  stockholders is determined by subtracting from
     net income  dividends  paid on  preferred  stock which were $38,000 for the
     quarter  ended  September  30, 2001 and  $115,000 for the nine months ended
     September  30, 2001.  The  difference  between  basic and diluted  weighted
     average  number of common  shares  outstanding  is the  effect of  dilutive
     common stock options outstanding.

4.   Refer to the  Annual  Report on Form 10-K for the year ended  December  31,
     2000  for  a  summary  of  significant  accounting  policies  and  detailed
     information regarding the financial statement presentation.

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

6.   On September 28, 2001,  the Company  issued  unsecured $20 million Series D
     7.13%  30-year  Senior  Notes.  The issue was  completed  through a private
     placement with two insurance companies.

7.   The Company entered into new short-term bank credit  agreements  dated July
     31, 2001. The new agreements,  which expire on April 30, 2003,  replace the
     prior bank short-term  borrowing  agreements.  The new agreement allows for
     unsecured short-term  borrowings of up to $60 million at the prime or lower
     rates quoted by the banks.

8.   In July 2001, the Financial Accounting Standards Board issued Statement No.
     141,  "Business  Combinations",  and Statement No. 142, "Goodwill and Other
     Intangible Assets".  Statement No. 141 requires that the purchase method of
     accounting be used for all business  combinations  initiated after June 30,
     2001 as well as all purchase method business  combinations  completed after
     June 30, 2001.  Statement No. 141


     also specifies  conditions  that  intangible  assets acquired in a purchase
     method business  combination  must meet to be recognized and reported apart
     from  goodwill.  Statement No. 142 specifies  that goodwill and  intangible
     assets with indefinite useful lives no longer be amortized,  but instead be
     tested for impairment at least  annually in accordance  with the provisions
     of Statement  No. 142.  Statement  No. 142 also  requires  that  intangible
     assets with determinable  useful lives be amortized over their useful lives
     to  their  estimated  residual  values,  and  reviewed  for  impairment  in
     accordance  with  Statement  No. 121,  "Accounting  for the  Impairment  of
     Long-Lived Assets" and for "Long-Lived Assets to be Disposed of".

         The Company is required to adopt the  provisions  of Statement  No. 141
     immediately.  The  Company  is  not  involved  in  a  business  combination
     initiated  prior to July 1, 2001 that it expected to be accounted for using
     the  pooling-of-interests  method.  Statement  No. 142 is effective for the
     Company on January 1, 2002.

         The  Company  has not yet  completed  a full  review of the impact that
     adopting Statements No. 141 and No. 142 will have on its financial position
     or results of operations.  However, on a preliminary basis the Company does
     not expect  either  statement  to have a material  impact on its  financial
     position or results of operations.

         In June 2001,  Statement of  Financial  Accounting  Standards  No. 143,
     "Accounting  for Asset  Retirement  Obligations"  of long-lived  assets was
     issued.  The statement is effective for fiscal years  beginning  after June
     15,  2003.  The Company  has not yet  completed a full review of the impact
     that adopting the statement will have on its financial  position or results
     of  operations,  and  therefore is unable to state the impact that adopting
     the statement will have on its financial position or results of operations.

         In August 2001,  Statement No. 144,  "Accounting  for the Impairment or
     Disposal  of  Long-Lived  Assets"  was  issued.  The  statement  sets forth
     requirements for measuring impairment of a long-lived asset that is defined
     as the condition that exists when the carrying amount of a long-lived asset
     exceeds its fair value. The statement also establishes criteria in which an
     impairment  loss must be  recognized.  The Company has not yet  completed a
     full assessment of the impact of adopting this statement,  and therefore is
     uncertain  as to the impact that  adopting the  statement  will have on its
     financial position or results of operations. The statement is effective for
     the Company in 2002.



Item 2

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

FORWARD LOOKING STATEMENTS

         This Form 10Q contains  forward-looking  statements intended to qualify
for  "safe  harbor"  within  the  meaning  of the  Federal  securities  laws  as
established  by the  Private  Securities  Litigation  Reform  Act of 1995.  Such
statements  are  based  on  currently   available   information,   expectations,
estimates,   assumptions  and  projections,   and  management's  judgment  about
California Water Service Group (Company), the water utility industry and general
economic  conditions.   Words  such  as  "expects,   intends,  plans,  believes,
estimates,  anticipates" 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.  Actual  results may vary  materially
from what is contained in a forward-looking statement. Factors which may cause a
result  different  than  expected  or  anticipated  include:   governmental  and
regulatory commissions'  decisions,  changes in regulatory commissions' policies
or procedures, the timeliness of regulatory commissions' actions concerning rate
relief, new legislation,  electric power  interruption,  increases in suppliers'
prices and the  availability of supplies,  changes in  environmental  compliance
requirements,  acquisitions,  the  ability to  successfully  implement  business
plans,  changes  in  customer  water use  patterns  and the impact of weather on
operating results,  especially as it impacts water sales. The Company assumes no
obligation to provide public updates of forward-looking statements.

RESULTS FOR THE THIRD QUARTER

         Third quarter 2001 net income was  $5,920,000,  equivalent to $0.39 per
common share on a diluted basis compared to the $9,205,000 or $0.60 per share on
a diluted basis last year.  Operating revenue decreased 0.4% to $76,310,000 from
$76,580,000  in 2000.  Cooler  weather,  especially  in the southern  California
service areas,  caused a decline in customers' water usage and resulted in lower
revenue for the quarter.  Revenue from existing  customers  declined  $2,450,000
because of the lower usage.  Offsetting  the decline in usage was  $1,519,000 of
additional revenue from rate increases and $661,000 from usage by new customers.
The following table shows the change in revenue:

         Decreased consumption by existing customers         ($2,450,000)
         Rate increases                                        1,519,000
         Usage by 5,700 new customers                            661,000
                                                              ----------
              Net revenue decrease                             ($270,000)
                                                              ==========



         Total  operating  expenses  increased  5% compared to last year's third
quarter.  Water  production  was 3% higher,  however,  water  production  costs,
consisting  of  purchased  water,  purchased  electric  power  and  pump  taxes,
increased  10%.  Water  production  costs are the  largest  components  of total
operating  expenses.  Together these costs  accounted for 52% of total operating
expenses,  2% more than last year.  Well  production  provided  55% of the water
supply, 45% was purchased from wholesale suppliers and less than one percent was
developed  from surface  supplies  processed  through the  Company's two surface
water treatment plants. The components of water production costs and the changes
from last year are shown in the table below:

                                               3rd Quarter
                                                 2001 Cost              Change
                                               -----------            ----------
         Purchased water                       $23,592,000            ($285,000)
         Purchased power                         9,101,000             3,205,000
         Pump taxes                              2,344,000               389,000
                                               -----------            ----------
              Total                            $35,037,000            $3,309,000
                                               ===========            ==========

         Purchased  water  rates  charged  by  wholesalers  increased  in  seven
districts. Despite the increases,  purchased water cost decreased due to reduced
customer  usage that  resulted in a decline in water  purchases,  and a shift to
using more well water.  The 3rd quarter was the first quarter fully  impacted by
higher electric rates.  Compared to last year, the Company's California electric
suppliers' rates rose 48% and electric rates in Washington were 27% higher.  The
higher rates  combined  with a 3% increase in water pumping  increased  electric
costs by $3,205,000.  Pump taxes increased  because of higher tax rates and more
pumping in districts subject to a pump tax.

          Also increasing other operations expense was the impact of the general
wage  increase  that was  effective at the start of the year,  additional  hours
worked and increases in related employee benefits.

         Maintenance  expense  decreased  $30,000  due to a slight  decrease  in
maintenance expenditures for water main and service line repairs.

         Federal and state income taxes decreased  $1,946,000 due to the decline
in income.

         Other income for the quarter was $420,000, an increase of 17% over last
year. There were no real estate sales this quarter,  however, a real estate sale
was  completed in October 2001 and will be reported in the fourth  quarter 2001.
It will contribute $2,700,000 to pretax income.

         Interest  expense on  long-term  debt rose  $249,000  over 2000's third
quarter  because of the  issuance  in late  September  2001 of the $20  million,
Series D 7.13%  senior  notes,  and the Series C senior  notes issued in October
2000 that were not outstanding in 2000's third quarter.  Other interest  expense
decreased  $167,000 due to lower interest rates.  The increase in borrowings was
necessary because of higher operating expenses, particularly for purchased power
costs, and delays in receiving  timely  California  Public Utilities  Commission
(CPUC) rate decisions.


RESULTS FOR THE NINE MONTHS

         Net  income  for  the  nine  months  ending   September  30,  2001  was
$11,905,000, equivalent to $0.77 per common share on a diluted basis compared to
the $1.08 per common  share on a diluted  basis  earned for the same period last
year. As discussed  below,  the earnings  comparison was impacted by this year's
lower water  sales,  increases in electric  rates and delays in  receiving  rate
increases from the CPUC.

         Operating  revenue  increased  $1,037,000 to  $190,276,000.  The higher
revenue was  primarily  due to rate  increases  and revenue from new  customers.
Since  January  1,  2001,  the  Company  added  5,200  new  customers.   Average
consumption per metered customer  decreased 2 percent from last year and average
revenue  per  customer  decreased  $3.06.  A  breakdown  of the net  increase in
operating revenue is accounted for in the following table:

         Decreased consumption by existing customers        ($4,378,000)
         Rate increases                                       3,642,000
         Usage by new customers                               1,773,000

         Total operating  expenses  increased 4%. Water  production  declined 1%
from last year.  Well  production  provided 52% of the supply with 47% purchased
from wholesale  suppliers and 1% produced through the treatment plants.  Despite
the decrease in production,  water production costs increased  $3,949,000 mainly
due to electrical rate increases. The components of water production expense and
the changes from last year are shown in the table below:

         In  addition  to  water  production  costs,  other  operations  expense
categories increased  $3,706,000.  A 3% general wage increase that was effective
at the start of the year and  additional  hours  worked  added to  expense.  The
increase in wages also caused higher employee  benefits  expenses.  During 2000,
$2,718,000 of expenses related to the Dominguez merger was recorded that did not
recur in 2001.

         Maintenance  expenses were higher by $215,000 or 3% over last year. The
higher costs related to pump stations, and main and service line repairs.

         Depreciation  and  amortization  expense  increased  due  to  a  higher
depreciable plant investment.

         Federal and state  income  taxes were lower due to a decline in income.


         Net other income was  $2,622,000 in 2001  compared to  $1,310,000  last
year.  Other income in 2001 includes  $1,282,000  from surplus  property  sales.
There were no property sales recorded in 2000.

REGULATORY MATTERS

         Electric  power rates  charged by suppliers  increased 10% in the first
quarter and another 38% in May.  Promptly after the May increase was known,  the
Company filed  applications  with the CPUC to recover the increased  power costs
for 24  districts  under  established  offset cost  recovery  balancing  account
procedures. In September 2001, the CPUC authorized offset rate increases for two
districts  totaling  $2,175,000  in annual  revenue.  For 2001,  the offset rate
increases are expected to increase revenue by approximately  $735,000.  The CPUC
deferred  decisions for the other 22 districts.  Those  decisions will likely be
processed as part of the 2001 General Rate Case (GRC)  applications.  Subsequent
to its  September  decisions,  the CPUC  proposed  changes  to the  offset  cost
recovery balancing account process.  Adoption of the proposed  revisions,  which
the CPCU will  consider  in  separate  rulemaking  proceedings,  could  deny the
Company  recovery of some or all of the power cost  increases  that have already
been incurred or will be incurred in the future.

         CPUC decisions were received in September 2001 for two of the three GRC
applications  filed  during  the  summer  of  2000.  The  decisions   authorized
additional annual revenue of $2,890,000.  In 2001, the decisions are expected to
add  approximately  $980,000 to revenue.  A decision for the third  district was
denied and that GRC will likely be included in the 2001 GRC filings.

         In September,  the Company  submitted GRC  applications  to the CPUC to
increase  rates  for 16 of  California  Water  Service  Company's  24  regulated
districts.  These  districts  represent  over 60  percent  of  total  California
customers.  The  application  requests a 10.75% return on equity and  additional
annual revenue of $19 million. Under the Commission's  guidelines for processing
GRC  applications,  the Company would expect  decisions would be received in the
second  quarter of 2002.  However,  the Company  has noted that in recent  water
industry  proceedings,   the  Commission  has  not  adhered  to  its  processing
guidelines.  The schedule  for this series of  applications  indicates  that the
Company may not receive  decisions until the third quarter of 2002.  Included in
the $19  million is an open  application  for $5.9  million  covering  increased
General  Office  expenses.  The CPUC  staff  and the  Company  had  agreed  on a
stipulated  settlement for the General  Office cost recovery  earlier this year.
However,  the staff later reconsidered its position and deferred the matter. The
Company estimates that it might receive a decision concerning the General Office
costs in the second quarter of 2002.

LIQUIDITY

         On September 28, 2001, the Company issued  unsecured $20 million Series
D 7.13%  30-year  Senior  Notes.  The  issue  was  completed  through  a private
placement with two insurance companies.




         The Company  entered into new short-term bank credit  agreements  dated
July 31, 2001. The new agreements,  which expire on April 30, 2003,  replace the
prior  bank  short-term  borrowing  agreements.  The new  agreement  allows  for
unsecured short-term borrowings of up to $60 million at the prime or lower rates
quoted by the banks.

         Short-term  bank borrowings were reduced to $6,000,000 at September 30,
2001 with  proceeds from the issuance of the Series D senior notes and cash from
operations.  The bank borrowings were reduced to $3,000,000 during October 2001.
At September 30, 2000, short-term bank borrowings were $14,598,000.  On November
1, 2001  additional  short-term bank borrowings will be necessary to fund annual
sinking fund and  semi-annual  interest  payments on first mortgage  bonds,  and
semi-annual interest payments on other debt obligations.

         On August 15, 2001,  the third quarter  common and preferred  dividends
were paid. The fourth quarter common  dividend will be paid on November 15, 2001
at $0.27875 per share as approved by the Board of Directors at their October 24,
2001  meeting.  This is the 228th  consecutive  quarterly  dividend  paid by the
Company.  Annualized, the 2001 dividend rate is $1.115 per common share compared
to $1.10 in 2000.  Because of lower earnings,  the dividend payout ratio for the
12-month period ending September 30, 2001 is 111%.

         No new common shares were issued during the quarter.

         Book value per common  share was $13.09 at September  30, 2001.  During
the quarter,  gross utility plant  expenditures  (Company and developer  funded)
totaled  $12,176,000  for additions to and  replacements  of utility plant. On a
year-to-date  basis, gross plant  expenditures have been $39,158,000.  The plant
expenditures  were  funded by  operations,  issuance  of Series D senior  notes,
short-term  bank  borrowings  and  funds  from  developers.   The  2001  Company
construction  budget,  which does not  include  developer  funded  projects,  is
$53,900,000.

WATER SUPPLY

         The  Company  believes  that its  various  sources of water  supply are
sufficient to meet customer demand for the remainder of the year.  Historically,
roughly half of the water source is purchased from wholesale  suppliers with the
other half pumped from wells.  A small portion is developed  through three local
surface treatment plants.

CALIFORNIA ENERGY SITUATION

         The California  energy crisis has been well publicized.  In response to
supply shortages, electric power rates have increased significantly.  During the
third  quarter,  California  was able to sustain  its energy  sources  and avoid
rolling electric blackouts. There is still uncertainty about the state's ability
to avoid future rolling electric blackouts. The Company continues its efforts to
use power as  efficiently  as possible and at the lowest cost to its  customers.
The  Company  maintains  backup  power  systems  to  continue  water  service to
customers if the power companies'  supplies are interrupted.  Many


wellsites are equipped with emergency  electric  generators.  The generators are
designed to produce  electricity to keep wells  operating  during power outages.
Storage tanks also provide customers with water during blackout periods.

ACCOUNTING PRONOUNCEMENTS

         Refer to Note 8 to  Condensed  Consolidated  Financial  Statements  for
information regarding issuance of Financial Accounting Standards Board Statement
No  141  "Business  Combinations",   Statement  No.  142,  "Goodwill  and  Other
Intangible  Assets",   Statement  No.  143,  "Accounting  for  Asset  Retirement
Obligations",  and Statement No. 144, "Accounting for the Impairment or Disposal
of Long-Lived Assets".

SEPTEMBER 11 TERRORIST ATTACKS

         The Company  shares in the  nation's  shock and  sadness  caused by the
September 11th terrorist attacks in New York, Washington DC and Pennsylvania. As
a result of the attacks,  the Company has heightened  security at its facilities
and taken added  precautions to safeguard our employees and the water we deliver
to our customers.

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 Company's  market risk to interest rate exposure is limited because
the cost of  long-term  financing,  including  interest  costs,  are  covered in
consumer  water rates as approved by the  Commission.  The Company does not have
foreign  operations,  therefore,  it does not have a foreign  currency  exchange
risk.

         The  Company's  sensitivity  to  commodity  prices is most  affected by
changes in purchased water and purchased power costs.  Through the  Commission's
balancing  account  procedures,  the Company has been able  historically pass on
increases in purchased  water and purchased  power costs to consumers;  recently
proposed  revisions to the CPUC's procedures may impair the Company's ability to
recover some or all of the increases.  The Company manages other commodity price
exposure through the duration and terms of its vendor contracts.
