material changes in the information disclosed in the notes to the consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2001 (the 2001 Annual Report).  The unaudited condensed consolidated
financial statements reflect all adjustments which, in our opinion, are necessary to present fairly the financial position of Southwest Water as of September 30, 2002, and our results of operations and cash flows for the periods ended September 30,
2002 and 2001. These adjustments are of a normal recurring nature.

Certain amounts in our prior period financial statements have been
reclassified to conform to the current period presentation.

Note 2.  Operating Segments

Our operating structure includes our Services Group and our Utility Group.  We have not changed the basis of segmentation or measurement of segment profit or
loss from the information reported in our 2001 Annual Report.

Our Services Group consists of contract service businesses within which we
operate and manage water delivery and wastewater treatment facilities owned by cities, public agencies, municipal utility districts and private entities in Texas, New Mexico, California, Mississippi and Georgia. We also provide contract public works
services in Mississippi and Georgia. Nationwide, we provide utility submetering and billing and collection services. Our Services Group companies may be subject to regulatory oversight; however, the pricing of our services is not subject to
regulation.

Within our Utility Group, we own and operate rate-regulated public water and wastewater utilities in California, New Mexico
and Texas. State regulatory agencies oversee the operations of our utilities and establish the rates that we can charge for our water delivery and wastewater services.

Note 3.  Seasonality

Our Utility Group water operations are seasonal because rainfall and weather conditions affect water consumption. The second and third quarters of each year typically
account for the highest volume of water consumption when weather tends to be hot and dry.  The results of operations for one quarter do not indicate results to be expected in another quarter. Drought conditions may result in lower revenue due
to consumer conservation efforts and a shortage of water. Drought conditions may also result in increased water costs to us, which could adversely affect our profitability. Conversely, unusually wet conditions may result in decreased customer
demand, lower revenues and lower profit in our utility operations. Utility Group wastewater operations are generally not affected by seasonality.

Our Services Group operations can be affected by weather and rainfall. In general, heavy rainfall or storm conditions may limit our ability to perform certain
billable work such as pipeline maintenance, manhole rehabilitation and other outdoor services. Severe weather conditions may also result in additional labor and material costs to us that may not necessarily be recoverable from the various cities
that have operations and maintenance contracts with us.

Note 4.  Earnings Per Share, Stock Options and Stock Dividends

We record earnings per share (EPS) by computing basic EPS and diluted EPS in accordance with US GAAP. Basic EPS measures our performance over
the reporting period by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted EPS measures our performance over the reporting period after giving effect to all
potentially dilutive common shares that would have been outstanding if the dilutive common shares had been issued. Stock options, convertible debentures and warrants give rise to potentially dilutive common shares. On September 25, 2001, our Board
of Directors declared a five percent stock dividend, payable on October 22, 2001 to stockholders of record on October 1, 2001. All per share amounts and numbers of shares outstanding reflect this dividend.

Note 5.  Balancing Account

Our California water utility has recorded a balancing account
receivable in the amount of approximately $2,300,000, representing certain uncontrollable costs that we incurred over the past few years. Historically, the California Public Utilities Commission (CPUC) allowed such balancing accounts to be recorded
in the income statements of water utilities, with a corresponding liability or asset on the balance sheet. However, on December 1, 2001, the CPUC adopted a resolution that changed its long-standing policies and procedures with respect to balancing
accounts, effectively eliminating such accounts for future periods. In April 2002, our California water utility filed a rate case and has applied to recover the $2,300,000, balancing account receivable. During 2002, our California water utility has
recognized all water costs as incurred and will attempt to recover these costs in future regularly scheduled rate hearings.

Note 6.  Accounting Pronouncements

Effective January 1, 2002, we adopted Statement of Financial Accounting Standards (SFAS) No. 142, Goodwill and Other Intangible Assets, under which goodwill is no
longer subject to amortization over its estimated useful life. Instead, goodwill is reviewed for impairment on an annual basis (or more frequently if circumstances indicate a possible impairment) by means of a fair-value-based test. As of September
30, 2002, goodwill totaled approximately $14,030,000.

The following table provides information about prior goodwill amortization and its
impact on basic and diluted EPS.

Effective January 2002, we were subject to SFAS No. 144, Accounting for
the Impairment or Disposal of Long-Lived Assets. SFAS No. 144 requires that long-lived assets be tested for recoverability when events or changes in circumstances indicate carrying amounts may not be realizable. SFAS No. 144 does not apply to
goodwill impairment, which is accounted for under SFAS No. 142. SFAS No. 144 further clarifies the methods of accounting for assets that are disposed of. We regularly review assets for impairment. The implementation of SFAS No. 144 did not have any
effect on our results of operations or financial condition.

Note 7.  Acquisitions

AquaSource, Inc. (AquaSource)

During the third
quarter of 2002, we completed negotiations for the acquisition of a part of AquaSources water and wastewater contract operations. The acquisition includes AquaSources contract operations in Colorado and the Houston, Texas, area. We
expect the purchase price, after adjustments, to exceed $10,500,000 in cash, and we expect closing of the acquisition to occur in the fourth quarter of 2002.

Master Tek International, Inc. (MasterTek)

From April 3, 2000 through March 31, 2002, we owned 80% of Master Tek. Under the terms of our purchase agreement, the minority owner of Master Tek may require us to
purchase his initial minority interest in 5% increments at a price not to exceed $1,000,000 per year over four years. In April 2002 we paid $1,000,000 to the minority owner for an additional 5% interest in Master Tek in accordance with the purchase
agreement, and we may be required to purchase the remaining minority interest over the next three years.

Note 8.  Non-Recurring Items

Groundwater Settlement

The water supply of our
California water utility has been affected by the presence of certain groundwater contaminants. These contaminants consist mainly of chemicals disposed of by various industrial companies in the 1940s and 1950s. In 2001and 2002, this contamination
necessitated the shut-down of a number of our wells, and we have had to purchase water at a cost substantially higher than the cost of water pumped from our own wells.

In May 2002, a settlement was reached among some of the alleged polluters and a number of water companies, including our California water utility. As part of the
settlement, in the second quarter of 2002, we accrued income of approximately $1,616,000 and received payments, primarily representing reimbursement of certain water and energy costs incurred in 2000 and 2001. (Additionally, as part of the
settlement, we have received payments in 2002 and expect to continue to receive payments in future periods from this settlement for the incremental cost of purchasing water rather than pumping from our shut-down wells. We bill and collect this
reimbursement each month, and the amounts are recorded as a reduction of water costs included in direct operating expenses. The settlement also provides capital contributions to construct additional interconnections with other water sources. Funds
from the settlement will also be used to develop long-term solutions that will potentially enable us to use our own less costly groundwater supplies in the future.)

Pension Plan Termination

Southwest Water
terminated a non-contributory defined benefit plan (the Pension Plan) as of December 30, 1999. In January 2002, the net assets of the Pension Plan were distributed to plan participants as specified by the Employee Retirement Income Security Act and
its related regulations (ERISA). Following distribution of approximately $14,400,000 to satisfy the pension benefit obligation and settlement of expenses paid by the Pension Plan in accordance with ERISA, the Pension Plan had excess assets of
approximately $1,200,000. Under the provisions of SFAS No. 88, Employers Accounting for Settlements and Curtailments of Defined Benefit Pension Plans and for Termination Benefits, we recognized a pretax termination gain of approximately
$980,000 in the first quarter of 2002.

Item 2:
Managements Discussion and Analysis of Financial Condition and Results of Operations

RESULTS OF OPERATIONS

Net Operating Revenues and Operating Income

Services Group

Services Group operating revenues for the third quarter of 2002 were $19,243,000, an increase of 13% from $16,967,000 in 2001. For the first nine months of 2002,
operating revenues were $55,609,000, an increase of 20% from $46,174,000 in 2001. Both the quarter and the year-to-date increases were due primarily to the acquisition of Operations Technologies, Inc. (OpTech) in August 2001. Services Group third
quarter and year-to-date revenues increased overall; however, submetering revenues decreased, primarily as a result of a large construction project completed during 2001 with no similar project in 2002.

Services Group operating income decreased to $815,000 in the third quarter of 2002, a decrease of 16% from $968,000 in the comparable period of 2001. For the first
nine months of 2002, Services Group operating income decreased 1% to $1,822,000 from $1,836,000 in 2001. In the third quarter of 2002, Services Group operating income decreased $153,000 primarily due to significant increases in liability insurance
costs, legal expenses, payroll-related expenses and rent expenses. Services Group 2002 operating income for the third quarter and year-to-date reflects the acquisition of OpTech in August 2001; however, decreased operating income from submetering
offset much of this benefit because of a large construction project completed during 2001 with no similar project in 2002.

Utility
Group

Utility Group revenues for the third quarter increased 2% to $15,331,000 from $15,068,000 in the comparable period of 2001.
Year to date, utility revenues increased to $39,879,000, an increase of 8% from $36,914,000 in 2001. Water operations are seasonal because rainfall and weather conditions affect customer water consumption. Water usage increased 1% for the quarter
and 8% overall at our California utility because of hot, dry weather in the third quarter and drought-like conditions during the first nine months of 2002. Water usage increased 1% for the quarter and 4% overall in New Mexico, primarily reflecting a
10% addition of new customers. The effects of a rate increase at one of our Texas utilities also contributed to the increase in operating revenues.

Utility Group operating income decreased 21% to $3,707,000 in the third quarter of 2002 from $4,682,000 in the comparable period of 2001. Year to date, Utility Group
operating income decreased 5% to $10,224,000 from $10,721,000 in 2001. The decrease in operating income primarily resulted because of the effect of higher water-volume-related expenses for the 2002 periods incurred at our California utility. 
In addition, in 2001, our California utility was able to defer recognizing certain costs until future rate cases through the use of a balancing account. As of December 1, 2001, the CPUC eliminated the use of balancing accounts which negatively
impacted our California utilitys operating income. This decrease was partially offset by a rate increase at one of our Texas utilities, which positively impacted operating income.

Selling, General and Administrative Expenses

Total selling, general and administrative expenses
decreased 15% to $3,726,000 during the quarter ended September 30, 2002, compared to $4,358,000 for the comparable period in 2001. Total selling, general and administrative expenses increased 14% to $13,709,000 during the nine months ended September
30, 2002, compared to $12,046,000 for the same period in 2001.  In the third quarter of 2002,

---

health-insurance-related expenses decreased by approximately $400,000, as we adjusted our liability for unreported claims to
reflect current claims activity. Our health insurance plan year ended June 30, 2002. We incurred health claim expenses at a lower rate than anticipated at the beginning of the plan year.

Selling, general and administrative expenses increased during the nine months ended September 30, 2002 as a result of increases in liability insurance,
payroll-related expenses and marketing and new business development expenses. Reflected in the first nine months of 2002 is approximately $830,000 of marketing and new business development expenses incurred primarily in the second quarter associated
with the potential design-build-finance-operate concept for a reverse osmosis water treatment plant in California, expenses related to a potential major new contract in Florida, and expenses related to a possible acquisition.   During the
third quarter of 2002, certain events occurred with respect to these three initiatives.  First, we were unsuccessful in obtaining the major new contract in Florida and we recognized marketing and new business development expenses for the
Florida project.   Second, we incurred additional marketing and new business development expenses associated with the potential design-build-finance-operate concept for a reverse osmosis water treatment plant in California, bringing our
total expenses to date for this project to approximately $614,000.  We cannot assure you as to the successful completion of the negotiations relating to this water treatment plant.  Finally, we were successful in negotiating the
acquisition of the majority of AquaSource, Inc.s water and wastewater contract operations business.

Other Income and Expense

Interest Expense

Total interest expense
increased 1% to $1,058,000, during the quarter ended September 30, 2002, compared to $1,046,000 for the comparable period in 2001. Total interest expense increased 16% to $3,277,000 during the nine months ended September 30, 2002, compared to
$2,833,000 in the same period of 2001. The increase reflects interest expense on our 20-year convertible subordinate debentures that were issued in July 2001.  This increase was partially offset by decreases in the interest expense on our bank
lines of credit because we paid down a portion of our line of credit borrowing with the proceeds from the debentures. Our year-to-date and third quarter interest expense on the bank lines of credit also decreased due to generally lower interest
rates in 2002, compared to 2001. The reduction in capitalized interest during the year-to-date and third quarter of 2002, compared to the same periods in the prior year was due primarily to a reduction in company-financed utility projects.

The major components of interest expense for the three months ended September 30, 2002 and 2001 are as follows:

|                                                      |  | 2002           |       | 2001 |

Water-Related Cost
Reimbursement

In the second quarter of 2002, we accrued income for a reimbursement of approximately $1,616,000 for
water-quality-related expenses incurred in 2001 and 2000. Additionally, in 2002, we received and will continue to receive payments from this settlement for the incremental cost of purchasing water rather than pumping from our shut-down wells. We
bill and collect this reimbursement each month and the amounts are recorded as a reduction against water costs included in direct operating expenses.

Other

In the first quarter of 2002, we
recorded a one-time pre tax gain on a pension plan termination of $980,000. This increase in other income was partially offset by amortization of contracts related to the purchase of OpTech in August 2001.

Income Taxes

Our effective tax rate was 35% for the third quarter of 2002 and the first nine
months of 2002, compared to 37% for both comparable periods in 2001. Our effective tax rate was impacted when we recorded a one-time gain on termination of a pension plan, which is excluded from ordinary taxable income. For the calendar year 2002,
we expect our ongoing tax rate to be between 33% and 35%.

FINANCIAL CONDITION

Liquidity and Financial Position

Our liquidity is influenced primarily by cash flows from operations, and by capital expenditures at our Utility Group for the addition, replacement
and renovation of water and wastewater utility facilities. Our capital resources are used for debt service on our bonds and debentures and are also influenced by investments in new business opportunities, including the acquisition of companies,
funding of projects and acquisition of contracts.

As of September 30, 2002, we had cash and cash-equivalent balances totaling $1,715,000
and aggregate lines of credit totaling $24,000,000 consisting of three separate unsecured lines of credit from three commercial banks. Two of the lines of credit expire in July 2004. The remaining $4,000,000 line, with no balance outstanding as of
September 30, 2002, was renewed in April 2002 and now expires in April 2004. As of September 30, 2002, we had $5,245,000 outstanding on these lines of credit. During the first nine months of 2002 our outstanding line of credit borrowings decreased
by $10,747,000. We paid

10



---

down our lines of credit primarily with the net proceeds of approximately $9,750,000 from a new bank term loan secured by our
Texas utility (and discussed below), the cash received as payment for the reverse osmosis plant, and from payments received for water-quality-related reimbursements. We also paid in full our New Mexico utility Series A First Mortgage Bonds in the
amount of $2,000,000, and we purchased certain utility property.

In addition to our lines of credit, we have excess borrowing capacity
under our First Mortgage Bond Indentures of approximately $63,000,000 as of September 30, 2002. However, the additional borrowing available under our current commercial lines of credit is limited by financial covenants that restrict additional
borrowing at September 30, 2002 to an amount no greater than the remaining unused credit line amount. Additional borrowing outside our lines of credit requires bank approval.

We expect to maintain our lines of credit in the normal course of business. Each of the line of credit agreements contains certain financial covenants. As of
September 30, 2002, we were in compliance with all applicable covenants of each of the line of credit agreements.

We anticipate that our
available line of credit borrowing capacity and cash flows generated from operations will be sufficient to fund our activities during the next 12 months. If we were unable to renew our existing lines of credit, our capital spending or acquisitions
would be reduced or delayed until new financing arrangements were secured. Such financing arrangements could include seeking debt or equity financing through a private placement or a public offering. Similarly, if additional cash were needed to fund
an acquisition, financing arrangements could include long-term borrowing or equity financing.

Net Cash Flow Provided by Operations

In the first nine months of 2002, net cash provided by operations totaled $11,334,000 compared to $1,448,000 in the same period of 2001. Increased cash flows from
operations were primarily the result of the collection of significant receivables in connection with the completion of a reverse-osmosis water treatment plant constructed by one of our Services Group companies. In addition, we received approximately
$2,000,000 in cash payments for certain water-quality-related expenses incurred in prior years and for prior year capital cost reimbursements.

Financing Activities

Our financing activities include net proceeds from the issuance of long-term debt, net borrowings on our lines of credit, dividend payments and
stock transactions among other items.

In August 2002 we entered into a ten-year, $10,000,000 secured bank term loan. The net proceeds of
approximately $9,750,000 were used to pay down our bank lines of credit. The term loan bears interest at a rate equal to LIBOR plus 1.75%, with principal payments of $125,000 due quarterly, beginning in November 2002. The note is secured by
substantially all of the assets of one of our Texas utilities.

On July 20, 2001, Southwest Water issued $20,000,000 of 6.85% fixed rate
convertible subordinate debentures, due July 1, 2021, and received net proceeds of approximately $18,890,000 from the sale after underwriting discounts, commissions and other expenses of the offering.  The net proceeds from the sale of these
debentures were used to reduce borrowings on our revolving bank lines of credit.

The debentures are convertible into shares of our
common stock at a conversion price of $17.007 per share, and are convertible at any time prior to maturity unless previously redeemed.  We may redeem the debentures in whole or in part at any time, at a redemption price of 105% at July 1, 2003
and declining 1% annually to par (100% of face value) after June 30, 2008.  The issuance costs of the

11



---

convertible subordinate debentures in the amount of approximately $1,110,000 are being amortized over 20 years. We are subject to
certain financial covenants under the terms of the indenture agreement for the convertible subordinate debentures.  As of September 30, 2002, we were in compliance with all applicable restrictions.

Investing Activities

Our investing activities include company-funded acquisitions of plant and
equipment as well as acquisitions.

Property, Plant and Equipment

During the first nine months of 2002, our additions to property, plant and equipment were $18,812,000, representing an increase of $6,467,000 from 2001. Additions to
property, plant and equipment were primarily utility plant for our Utility Group, including new well and transmission lines at our New Mexico utility and the construction of a lift station and force main, and an elevated storage tank at one of our
Texas utilities. In addition, we completed expansion of an office building in Austin, Texas. Developers made contributions in aid of construction (CIAC), Living Unit Equivalent (LUE) fees and advances totaling $13,220,000 during the first nine
months of 2002, of which $7,527,000 was received in cash and $5,693,000 was received as non-cash contributions of property. Company-financed capital additions were $5,592,000 funded primarily by cash flow from operations. We estimate that our total
company financed capital additions in 2002 will be approximately $11,000,000, primarily for utility plant, and that our cash flows from operations, borrowings on our lines of credit and CIAC will fund these additions.

Acquisitions

Under the terms of our
purchase agreement for Master Tek, the minority owner of Master Tek has the option to require us to purchase his initial 20% minority interest in 5% increments at a price not to exceed $1,000,000 per year over four years. The minority owner
exercised this option to sell us 5% of Master Tek stock for which we paid $1,000,000 in cash in April 2002. Under the terms of the OpTech purchase agreement, we have the right to acquire the remaining 10% of OpTech after five years based on a
formula relating to the profitability of OpTech.  In addition, after two years, the minority shareholder of OpTech has the option to sell the remaining 10% of OpTech to us using the same profitability formula which has a minimum threshold of
$1,000,000.

CRITICAL ACCOUNTING POLICIES

We consider certain accounting policies
critical in preparing our consolidated financial statements.  Certain of these policies require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of certain contingent assets
and liabilities at the date of the consolidated financial statements, as well as amounts of revenues and expenses during the reporting periods.  Actual results could differ from those estimates.  Our 2001 Annual Report includes detailed
descriptions of both our critical and significant accounting policies. The critical estimates and judgments made by management which influence the financial statements include the following:

Balancing Account

Our California utility has recorded a balancing account receivable in the amount of approximately $2,300,000, representing certain uncontrollable costs that we
incurred over the past few years.  Historically, the California Public Utilities Commission (CPUC) allowed such balancing accounts to be recorded in the income statements of water utilities, with a corresponding liability or asset on the
balance sheet.  However, on December 1, 2001, the CPUC adopted a resolution that changed its long-standing policies and procedures with respect to balancing accounts, effectively eliminating such accounts for future periods.  We believe
that Suburban will be able to recover the $2,300,000 recorded in its balancing account through the rate case filed with the CPUC in April 2002.  However, there can be no assurance that the CPUC will allow recovery of all or some of this
balance.  We have not recorded any allowance against the $2,300,000 asset on Suburbans balance sheet.

Collectibility of
Customer Receivables

We periodically evaluate the collectibility of our customer receivables, and provide an allowance for
uncollectible receivables based upon an estimate by management of the amount of receivables that might not be collectible.  This estimate is predicated upon a number of factors, including historical receivable write-off experience, a review of
customer accounts with past due uncollected balances, probable costs of collection and the general credit worthiness of our customers.  During the second and third quarters of 2002, we recorded increases of $200,000 and $25,000, respectively,
in our allowance for uncollectible receivables relating to our submetering subsidiary accounts.  We believe that our allowance for doubtful accounts is adequate as of September 30, 2002.

Inventory

We have approximately $2,000,000
of inventories included in other current assets as of September 30, 2001.  Our inventories consist primarily of transmitters and related parts used by our submetering business in its construction activities, as well as materials and supplies
used in our water supply and wastewater activities.  We believe that we have adequate reserves to offset the amount of obsolete inventory as of September 30, 2002.

DISCLOSURE CONTROLS AND
PROCEDURES

Our principal executive officer and principal financial officer are responsible for establishing and maintaining disclosure
controls and procedures (as defined in Exchange Act Rules 13a-14 and 15d-14) for Southwest Water, and we have designed such disclosure controls and procedures to ensure that material information relating to Southwest Water, including its
consolidated subsidiaries, is made known to us by management within these entities, particularly during the period in which this quarterly report is being prepared. In connection with this, our certifying officers have evaluated the effectiveness of
our disclosure controls and procedures as of a date within 90 days prior to the filing date of this Report on Form 10-Q for the quarter ended September 30, 2002 (the September Report).  We have presented in the September Report our conclusions
about the effectiveness of the disclosure controls and procedures based on our evaluation in November 2002.

FORWARD-LOOKING STATEMENTS

Certain written and oral statements made by our Company and subsidiaries or with the approval of an authorized executive officer of our Company may constitute
forward looking statements as defined under the Private Securities Litigation Reform Act of 1995, including statements made in this report and other filings with the Securities and Exchange Commission. Generally, the words
believe,

13



---

expect, intend, estimate, anticipate, project, will, and
similar expressions identify forward-looking statements, which generally are not historical in nature. All statements which address operating performance, events or developments that we expect or anticipate will occur in the future, including
statements relating to volume growth, share of sales and earnings per share are forward-looking statements. Forward-looking statements are subject to risk and uncertainties that could cause actual results to differ materially from our historical
experience and our present expectations or projections. When made, we believe that these forward-looking statements are reasonable. However, caution should be taken not to place undue reliance on any such forward-looking statements since such
statements speak only as of the date when made. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

The following are some of the factors that could cause our actual results to differ materially from the expected results described in or underlying our
forward-looking statements:

This list is not inclusive as to risk factors that we may experience and you are
advised to refer to the discussion in our 2001 Annual Report.

Item 3:
 Quantitative and Qualitative Disclosures About Market Risk

We have certain indebtedness that is subject to
variable interest rates. As a result, Southwest Waters interest expense is affected by changes in the general level of interest rates. Changes in interest rates affect the interest expense that we will pay on both the lines of credit and on
our new bank term loan. The highest interest rate that we could be charged on the lines of credit is the banks prime rate minus one-quarter percent.

Southwest Water is using the favorable low interest rates in the current market. In part to mitigate future market interest rate risk, we completed a $20,000,000,
20-year convertible subordinate debenture

offering in July 2001, which bears a fixed interest rate of 6.85% per annum. The proceeds were used to pay down our variable rate
indebtedness.  Our long-term debentures were sold with a fixed interest rate, and are not subject to market fluctuation of interest rates. Our debentures are convertible into common stock of Southwest Water and, at a certain EPS level, our
debentures will become dilutive in computing our earnings per share.  Our debentures were sold through a retail distribution network, and we believe they are widely held.

PART II
-
OTHER INFORMATION

Item 1.
 Legal Proceedings

In September 2002, one of our subsidiaries was named as a defendant in a lawsuit
alleging wrongful death as the result of a chlorine gas leak that occurred at one of our facilities in July 2000.  The decedent who was exposed to the gas leak was treated and released from the hospital on the next day.  He subsequently
died eleven months later of causes that we believe are unrelated to the chlorine gas exposure.  We deny any wrongdoing and will vigorously defend against the claim. Our umbrella liability insurance carrier is currently absorbing the costs of
defense of the lawsuit; however, we cannot predict the outcome of this lawsuit. Based upon information available at this time, we do not expect that this action will have a material adverse effect on our financial position, results of operations or
cash flows.

Southwest Water and one of our subsidiaries were named as a defendant in four lawsuits alleging injury and damages as the
result of a sewage spill which occurred at an Austin, Texas, sewage pumping station that we operate. In 2001, a settlement was reached with three of the plaintiffs. We have been defended and indemnified by our insurance carrier and we were required
to pay a $10,000 deductible on settlement of the claims.  The remaining lawsuit is pending at this date. Southwest Water continues to vigorously defend against this claim. At this time, we do not believe these actions will have a material
adverse effect on our financial position, results of operations or cash flows.

Southwest Water and a subsidiary have been named as
defendants in several lawsuits alleging water contamination in the San Gabriel Valley Main Basin.  The California Supreme Court (the Court) ruled in February 2002 that the plaintiffs cannot challenge the adequacy of the water quality standards
established by the CPUC. The plaintiffs may sue and collect damages from CPUC-regulated water companies only by proving that water delivered did not meet CPUC water quality standards. Our subsidiary believes that it has complied with CPUC water
quality standards. The Court directed that the cases be sent to a trial court for further proceedings. At this time eleven cases have been consolidated before a single judge. The parties are now engaged in initial discovery and motions to determine
whether, in light of the ruling by the Court, the plaintiffs can plead and prove alleged water contamination. Southwest Water and this subsidiary have requested defense and indemnification from our liability insurance carriers for these lawsuits.
Several of the liability insurance carriers are currently absorbing the costs of defense of the lawsuits. The Company cannot predict the outcome of these lawsuits. Based upon information available at this time, we do not expect that these actions
will have a material adverse effect on our financial position, results of operations or cash flows.
