SOUTHWEST WATER COMPANY AND SUBSIDIARIES

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, 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 are forward-looking statements. Forward-looking statements are subject to risks 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.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

Note 1.  Basis of Presentation

Southwest Water Company was incorporated in California in 1954 and reincorporated in Delaware in 1988. Southwest Water Company and our subsidiaries
(Southwest Water, the Company, or we, us or our) provide a broad range of services including water production and distribution, wastewater collection and treatment, public works services, customer billing and
service, and utility submetering. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (US GAAP) for interim financial
information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. They do not include all information and notes required by US GAAP for complete financial statements. There have been no 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, 2002 (the 2002 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 March 31, 2003, and our results of operations and cash flows for the three months ended March 31, 2003 and 2002. 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.  In 2002, we retroactively adopted the fair value based method of accounting for stock options as outlined in Statement of Financial Accounting Standards (SFAS) No. 123, Accounting for Stock-Based Compensation.
Accordingly, all prior periods presented have been restated to reflect compensation cost that would have been recognized under the fair value based accounting method for all options granted, modified or settled in fiscal years beginning after
December 15, 1994. See Note 5 for detailed information.

Note 2.  Operating Segments

Our operating structure includes two segments: our Services Group and our Utility Group.  We have not changed the basis of segmentation or measurement of segment
profit or loss from that reported in our 2002 Annual Report.

In our Services Group, we operate and maintain water supply and wastewater
treatment facilities owned by cities, public agencies, municipal utility districts and private entities in Texas, Mississippi,

##### Table of Contents

California, Georgia, New Mexico, Colorado and South Dakota. We provide utility submetering and billing and collection services nationwide. While state and federal agencies
issue regulations regarding standards of water quality, safety, environmental and other matters which affect these operations, the pricing of our services within the Services Group 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 and federal agencies
issue regulations regarding standards of water quality, safety, environmental and other matters which affect these operations, as well as establish the rates that we can charge for our water delivery and wastewater services.

Our Services Group has contracted with our utilities in Texas and New Mexico to perform operating services, normal maintenance and construction work and, in
addition, to manage capital projects for these utilities. These contracts were established utilizing terms and conditions equivalent to prevailing industry rates for similar work performed by our Services Group for non-affiliated entities.  In
accordance with SFAS No. 71, Accounting for the Effects of Certain Types of Regulation, we recognize  profit from contract work performed and do not eliminate the intercompany profit on the contract work performed when the contract price
is reasonable and it is probable that the costs and capital will be recoverable through the rate making process. Accordingly, the intercompany profit on such projects has not been eliminated in the accompanying condensed consolidated financial
statements.

(1) Total revenues include both revenues from external customers
and intersegment transactions. Intersegment revenues were $1,324,000 and $2,510,000 for the three months ended March 31, 2003 and 2002, respectively.

Note 3.  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. In 2002, our Board of Directors declared a five percent stock dividend to stockholders of record on January 1, 2003. All per share amounts and numbers of shares outstanding reflect this
dividend.

Note 4. - Balancing Account

Our California water utility has recorded a balancing account receivable in the amount of approximately $2,300,000, representing the difference between actual water
production costs incurred and California Public Utilities Commission (CPUC)adopted water production costs. Historically, the 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, the CPUC significantly changed this policy by eliminating the use of balancing accounts as of November 29, 2001. In December 2002, the CPUC issued a decision that we believe will allow our
water utility in California to recover the $2,300,000 that was in the balancing account prior to November 29, 2001. Beginning in December 2001, our water utility in California has recognized all water costs as incurred. Differences between actual
and CPUC-adopted water production costs are tracked in a memorandum account at our California water utility and we will attempt to recover these costs in future regularly scheduled rate hearings.

Note 5.  Adoption of New Accounting Policy  Stock-Based Compensation

We currently
sponsor two stock option plans. Prior to 2002, we accounted for those plans under the recognition and measurement provisions of the Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees, and related
Interpretations, under which no stock-based compensation cost was reflected, as all options granted under those plans had an exercise price equal to the market value of the underlying common stock on the date of grant. In 2002, we adopted the
fair value recognition provisions of SFAS No. 123. SFAS No. 123 requires that we value stock options issued based upon an option pricing model and recognize this value as an expense over the period in which the options vest. In accordance with the
provisions of SFAS No. 148, Accounting for Stock-Based Compensation  Transition and Disclosure, an amendment to FASB Statement No. 123. we have elected to recognize stock-based compensation using the retroactive restatement
method.  Under this change in accounting method, we have restated our accompanying condensed consolidated financial statements for the prior period presented in this Report on Form 10-Q for the quarter ended March 31, 2003 (the March Report) to
reflect stock-based compensation expense under a fair value based accounting method for all options granted, modified or settled in fiscal years beginning after December 15, 1994.

The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options that
do not have vesting restrictions and that are fully transferable.  In addition, option valuation models require us to make subjective assumptions including the expected future volatility of the stock price.  Because the stock options we
grant have characteristics that are significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the value of an estimate, in managements opinion, the existing option
valuation models, including Black-Scholes, do not necessarily provide a reliable single measure of the fair value of our employee stock options.

In the table below, the fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model with the following weighted
average assumptions used for grants in 2003 and 2002:

|                        |  | 2003 |      | 2002 |

A summary of the status of the changes to the employee stock option plan during the first three

Note 6.  New Accounting Pronouncements

In June 2001, the Financial Accounting Standards Board (FASB) issued SFAS No. 143, Accounting for Asset Retirement Obligations. SFAS No. 143 requires us to
record the fair value of an asset retirement obligation as a liability in the period in which we incur a legal obligation associated with the retirement of

8

##### Table of Contents

tangible long-lived assets that result from the acquisition, construction, development, and/or normal use of the assets. We will also record a corresponding asset that is
depreciated over the life of the asset. Subsequent to the initial measurement of the asset retirement obligation, the obligation will be adjusted at the end of each period to reflect the passage of time and changes in the estimated future cash flows
underlying the obligation. We adopted SFAS No. 143 on January 1, 2003. The adoption of SFAS No. 143 did not have a material effect on our consolidated financial statements.

In April 2002, the FASB issued SFAS No. 145, Rescission of FASB Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical Corrections.
SFAS No. 145 amends existing guidance on reporting gains and loss on the extinguishment of debt to prohibit the classification of the gain or loss as extraordinary. SFAS No. 145 also amends SFAS No. 13 to require sale-leaseback accounting for
certain lease modifications that have economic effects similar to sale-leaseback transactions. The provision of SFAS No. 145 related to the rescission of Statement No. 4 applied to fiscal years beginning after May 15, 2002. The provisions of SFAS
No. 145 related to Statement No. 13 were effective for transactions occurring after May 15, 2002. The adoption of SFAS No. 145 did not have a material effect on our consolidated financial statements.

In June 2002, the FASB issued SFAS No. 146, Accounting for Costs Associated with Exit or Disposal Activities. SFAS No. 146 addresses financial accounting and
reporting for costs associated with exit or disposable activities and nullifies Emerging Issues Task Force (EITF) Issue 94-3, Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity. The provisions
of SFAS No. 146 were effective for exit or disposal activities initiated after December 31, 2002. The adoption of SFAS No. 146 did not have a material effect on our consolidated financial statements.

In November 2002, the FASB issued Interpretation No. 45, Guarantors Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of
Indebtedness to Others, an interpretation of FASB Statements No. 5, 57 and 107 and a rescission of FASB Interpretation No. 34. This Interpretation elaborates on the disclosures to be made by a guarantor in its interim and annual financial
statements about its obligations under guarantees issued.  The Interpretation also clarifies that a guarantor is required to recognize, at inception of a guarantee, a liability for the fair value of the obligation undertaken.  The initial
recognition and measurement provisions of the Interpretation were applicable to guarantees issued or modified after December 31, 2002 and the disclosure requirements were effective for financial statements of interim and annual periods ending after
December 15, 2002. The adoption of Interpretation No. 45 did not have a material effect on our consolidated financial statements.

In
December 2002, the FASB issued SFAS No. 148, which amends FASB No. 123 to provide alternative methods of transition for a voluntary change to the fair value method of accounting for stock-based compensation. In addition, SFAS No. 148 amends the
disclosure requirements of Statement No. 123 to require prominent disclosures in both annual and interim financial statements. In 2002, we adopted the fair value recognition provisions of SFAS No. 123 and the related provisions of SFAS No. 148 using
the retroactive restatement method. See Note 5 for detailed information.

In January 2003, the FASB issued Interpretation No. 46,
Consolidation of Variable Interest Entities, an interpretation of Accounting Research Bulletin No. 51. This Interpretation addresses the consolidation by business enterprises of variable interest entities as defined in the
Interpretation.  The Interpretation applies immediately to variable interest in variable interest entities created or obtained after January 31, 2003.  The Interpretation is applied to the enterprise no later than the end of the first
annual reporting period beginning after June 15, 2003.    The Interpretation requires certain disclosures in financial statements issued after January 31, 2003 if it is reasonably possible that an entity will consolidate or disclose
information about variable interest entities when the Interpretation becomes effective. The

application of this interpretation is not expected to have a material effect on our consolidated financial statements.

In November 2002, the EITF finalized EITF No. 00-21, Accounting for Revenue Arrangements with Multiple Deliverables. EITF No. 00-21 is required to be adopted
for all new revenue arrangements entered into in fiscal years beginning after June 15, 2003 but alternatively would allow application of EITF No. 00-21 to existing contracts and record the effect of adoption as the cumulative effect of a change in
accounting principle. The adoption of EITF No. 00-21 is not expected to have a material effect on our consolidated financial statements.

Note 7.  Acquisitions

At March 31, 2003, the gross carrying amount of intangible contract costs was approximately $1,436,000 and accumulated amortization of these contracts
was approximately $444,000. Amortization expense for intangible contract costs for the quarter ended March 31, 2003 was approximately $72,000.

The changes in the carrying amount of goodwill for the year ended December 31, 2002 are as follows:

Aqua Services, LP (Aqua Services)

In November 2002, we acquired 100 % ownership of certain contract operations in Texas and Colorado of AquaSource, Inc. a provider of contract water and wastewater
services. The purchase price consisted of approximately $10,317,000 in cash. Upon closing of the transaction on November 22, 2002, we began operating a part of this business under the name Aqua Services while the remaining part was incorporated into
one of our existing subsidiaries.

Operations Technologies, Inc. (OpTech)

In August 2001, we purchased 90% of the outstanding stock of OpTech, a provider of contract water and wastewater and public works services in the southeastern United
States, for a purchase price of $8,248,000. The purchase price consisted of cash payments of $3,948,000, promissory notes of $3,000,000 and 96,580 shares of our common stock with a fair market value of approximately $1,300,000 at the date of
acquisition. The terms of the purchase are disclosed in our 2002 Annual Report. Under the terms of the purchase agreement, we have the right to acquire the remaining 10% of OpTech after a period of five years based upon a formula relating to the
profitability of OpTech. After two years, the minority owner of OpTech has the option to sell the remaining 10% of OpTech to us using the same formula.

Master Tek International, Inc. (Master Tek)

In April
2000, we purchased 80% of the outstanding stock of Master Tek for approximately $4,000,000 consisting of $2,000,000 in cash and a $2,000,000 promissory note. 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 which increased our ownership to 85%. In the first quarter of 2003, the minority owner of Master Tek exercised his option to sell to us an additional 5% of Master Tek for $1,000,000.  See Part II Item 1., Legal Proceedings
for a description of related litigation.

Note 8.  Non-Recurring Items

Groundwater Settlement

One of the water
sources of our water utility in California 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 2001 and 2002,
this contamination necessitated the shutdown of a number of our wells, and we have had to purchase replacement 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 water utility in California. As part of the
settlement, in 2002, we recorded income of approximately $1,649,000 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 2003, and we expect to continue to receive payments in future periods from this settlement until completion of remediation. The payments represent the incremental cost of purchasing water over the cost that would have been
incurred by us to pump water from our wells had they not been shut down as a result of contamination. We bill and collect this reimbursement each month. These amounts are recorded as a reduction of water costs included in direct operating expenses.
The settlement also provides capital contributions to construct new wells and 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

Prior to December 30, 1999,we had a non-contributory defined benefit pension plan (the Pension Plan) that was terminated as of December 30, 1999. In
January 2002, the net assets of the Pension Plan were distributed to plan participants as permitted by the Employee Retirement Income Security Act (ERISA) and its related regulations. Following distribution of the plan assets of approximately
$14,400,000 to meet the benefit liabilities of the Pension Plan, and settlement of expenses paid by the Pension Plan in accordance with ERISA and its related regulations, the Pension Plan had excess assets of approximately $1,150,000.

In February 2002, our Board of Directors approved the transfer of excess assets to a qualified replacement plan. The funds were transferred to the
Trustee of the qualified replacement plan in March 2002. We recognized a net termination gain of approximately $980,000 as income in the first quarter of 2002.

Note 9.  Seasonality

Our Utility Group
water operations are seasonal as 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 Group 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.

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

ADJUSTMENTS RELATED
TO STOCK OPTION ACCOUNTING

We currently sponsor two stock option plans. Prior to 2002, we accounted for those plans under the
recognition and measurement provisions of the APB Opinion No. 25 under which no stock-based compensation cost was reflected as all options granted under those plans had an exercise price equal to the market value of the underlying common stock on
the date of grant.

Effective in 2002, we adopted the fair value based method of accounting for stock options as outlined in SFAS No.
123. In accordance with the provisions of SFAS No. 148, we elected to recognize stock-based compensation using the retroactive restatement method. Accordingly, all prior periods presented have been restated to reflect compensation cost that would
have been recognized under the fair value based accounting method for all options granted, modified or settled in fiscal years beginning after December 15, 1994.

RESULTS OF
OPERATIONS

Net Operating Revenues and Operating Income

For the
first three months of 2003, we recognized revenues of $36,114,000, an increase of $7,946,000, or 28%, compared to the same period in 2002. In the first quarter of 2003, we recorded operating income of $921,000, a decrease of $946,000, or 51%,
compared to the first quarter of 2002. We recorded a net loss of $149,000 or a diluted loss per share of $0.02 in the first quarter of 2003 compared to diluted EPS of $0.11 in the first three months of 2002. The net loss for the first quarter of
2003 reflects the effect of reduced revenues and higher water-volume-related expenses incurred at our utility in California and increased general and administrative costs for employee heath benefits, insurance and compensation expenses. Net income
in 2002 reflects the impact of a one-time gain on the termination of a pension plan which added a $980,000 pretax gain and $0.06 per diluted EPS to our first quarter 2002 results. Also included in the first quarter 2002 operating income is a pretax
gain of $119,000 on the sale of land formerly used in utility operations which added $0.01 per diluted EPS.

##### Table of Contents

Services Group

Services Group operating revenues for the first quarter of 2003 were $25,188,000, an increase of 47% from $17,177,000 in 2002. The increase was due primarily to the
acquisition of Aqua Services in November 2002. Revenues also increased due to construction activities related to water distribution facilities in Texas and a reverse osmosis water treatment facility in San Juan Capistrano, California.

Services Group operating income was $35,000 in the first quarter of 2003, a decrease of 92% from $420,000 in the comparable period of
2002. Services Group operating income decreased as a result of higher costs of employee health benefits, insurance and compensation expenses. The decrease in operating income was partially offset by the operating income contribution from our
acquisition of Aqua Services in November 2002.

Utility Group

Utility Group revenues for the first three months of 2003 decreased to $10,926,000, a decrease of $65,000, or 1%, from the same period in 2002. In the first quarter
of 2003, water usage decreased at our utility in California  because of cool, damp weather compared to drought-like conditions throughout much of the first quarter of 2002. Water usage increased in New Mexico, primarily reflecting an increase
in the number of customers which partially offset the decrease in revenue at our water utility in California. A rate increase at one of our utilities in Texas also contributed to offset the decrease in revenues.

In the first quarter of 2003, our Utility Group operating income decreased 18% to $2,199,000 from $2,678,000 in the same period of 2002. The decrease in 2003
operating income resulted primarily from the effect of reduced revenues and higher water-volume-related expenses incurred at our utility in California. This decrease was partially offset by increased water usage at our utility in New Mexico, which
positively impacted operating income.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased 23% to $5,760,000 during the first quarter of 2003, compared to $4,683,000 in the same
period of 2002. As a percentage of consolidated revenues, selling, general and administrative expenses were 16% and 17% in 2003 and 2002, respectively. The 2003 increase in selling, general and administrative expenses was primarily attributable to
a) the acquisition of Aqua Services in November 2002, and b) higher costs of employee health benefits, insurance and compensation expenses.

Other Income and Expense

Interest Expense

Total interest
expense increased 4% to $1,197,000 during the first quarter of 2003, compared to $1,156,000 for the same period in 2002 due to higher average balances outstanding on our lines of credit in 2003.

Other

In the first quarter of 2002, we recorded a one-time gain on the termination of a pension plan of approximately $980,000, and a $119,000 gain on the sale of
land previously used in utility operations.

Income Taxes

Our
effective tax rate for first quarter of 2003 was 37% compared to approximately 35% in 2002. Our effective tax rate for 2002 reflected the benefit of a one-time gain on the termination of a pension plan, which was excluded from ordinary taxable
income.

Earnings Per Share

In the first quarter of 2003 we recorded
a diluted loss per share of $0.02 compared to diluted EPS of $0.11 in the first quarter of 2002. Our loss per share reflects the effect of lower revenues and higher water-volume-related expenses incurred at our utility in California and increased
costs of employee health benefits, insurance and compensation expenses. In the first quarter of 2002 a one-time gain on the termination of a pension plan and a gain on the sale of land formerly used in utility operations contributed $0.07 to diluted
EPS.

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 March 31, 2003 we had a working capital deficit of approximately $1,079,000 with cash and
cash-equivalent balances totaling approximately $1,432,000, as well as 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 April 2004
and the remaining line expires in September 2004. As of March 31, 2003, we had approximately $22,995,000 outstanding on these three lines of credit.  In March 2003, we entered into an agreement to amend one of our lines of credit
under

which the bank increased our line of credit capacity by $4,000,000 through December 31, 2003. Our total borrowing capacity available under our lines of credit as of March 31,
2003, including the amendment to extend an additional $4,000,000, was $5,005,000.

As of December 31, 2002, we had approximately
$20,158,000 outstanding on our lines of credit and $3,842,000 borrowing capacity available.

On January 8, 2003, we obtained an
additional unsecured line of credit facility in the amount of $3,430,000 from one of our commercial banks.  This facility was used to issue a $3,430,000 standby letter of credit as collateral for performance under the service contract for the
Capistrano Valley Water District (CVWD) to design and construct a reverse osmosis water treatment facility and associated wells.  This standby letter of credit is in force for the estimated two-year construction period of the project. 
Upon acceptance of the completed project by the CVWD, the standby letter of credit and the related credit facility will be terminated.

In addition to our lines of credit, we have excess borrowing capacity under our First Mortgage Bond Indentures of approximately $65,000,000 as of March 31, 2003.
However, the additional borrowing available under our current commercial lines of credit is limited by financial covenants that restrict additional borrowing  to an amount no greater than the remaining unused credit line amount.

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. During the three months ended March 31, 2003, we were in compliance with all applicable covenants under each of the line of credit agreements.

We are currently evaluating our capital structure and potential financing alternatives available to us to provide additional liquidity.  These alternatives
include increasing the size of our lines of credit, long-term asset-backed financing capacity in our regulated utilities, sale and leaseback of certain assets and administrative office space, and issuance of debt or equity in either public or
private offerings.  With the exception of an increase in the size of our lines of credit, we anticipate that these financing alternatives would enable us to substantially reduce the amounts currently outstanding on our lines of credit. 
While we believe that there will be investor and lender interest in these financing alternatives, there can be no assurance that we will be able to obtain such funding in 2003.

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, or if we were unable to execute additional financing alternatives, our capital spending and any future acquisitions would be reduced, eliminated or delayed.  While we
have the ability to take such actions during 2003, these actions could negatively impact our revenues, revenue growth, and profitability.

In the first quarter of 2003, net cash provided by operations totaled $1,130,000 compared to $4,337,000 for the same period in 2002

Investing Activities

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

##### Table of Contents

During the first quarter of 2003, our additions to property, plant and equipment were $5,690,000 consisting of
$3,498,000 in Company-financed additions, $1,261,000 in capital improvement reimbursements, and $931,000 in developer-paid contributions in aid of construction (CIAC), advances for construction and living unit equivalent (LUE) fees. Company-financed
capital additions were funded primarily by cash flow from operations and by borrowings on our bank lines of credit. Total additions to property, plant and equipment represented an increase of $2,168,000 compared to the first quarter of 2002.

Additions to property, plant and equipment were primarily for regulated water system assets for our Utility Group, including new wells
and transmission lines in New Mexico and the construction of a lift station, water line and an elevated storage tank in Texas.

Financing Activities

Our financing activities include reimbursements of capital improvement costs, CIAC, LUE fees, advances for construction, net borrowings on our lines of credit,
dividend payments, payments on long-term debt and stock transactions among other items.

On March 17, 2003, we entered into an agreement
to amend one of our lines of credit under which the bank increased our line of credit capacity by $4,000,000 through December 31, 2003.

CRITICAL ACCOUNTING POLICIES

The accounting policies described below are those we consider 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.

Recognition of
Revenues: Revenues for contract operations are billed based on a monthly fee to provide a specific level of service as outlined in each individual contract.  We usually bill for additional services provided beyond the scope of the base
contract on a time and materials basis as such services are rendered.  Revenues for construction projects are recorded using the percentage-of-completion method of accounting.

Revenues for submetering billing and collection services are recognized and billed at the end of the month in which services are performed.  Revenues for
installation of submetering equipment are accounted for using the percentage-of-completion method.

Water utility revenues are recognized
when amounts are billed to customers. An estimated amount for unbilled revenues is also recognized for water used toward the end of the accounting period.

Impairment of Goodwill: We have made acquisitions in the past that resulted in recording goodwill and intangible assets.  The balance sheets presented in
the consolidated financial statements include the goodwill and intangible customer contracts related to the 2002 acquisition of the contract services business of AquaSource, Inc., the goodwill and intangible contract value related to the 2001
acquisition of OpTech, and the goodwill and non-compete agreement related to the 2000 acquisition of Master Tek.  In June 2001, the FASB issued SFAS No. 142, Goodwill and Other Intangible Assets. SFAS No. 142 requires that goodwill and
intangible assets with indefinite useful lives are not amortized, but instead are tested for impairment at least annually. For intangible assets with definite useful lives, SFAS No. 142 requires amortization over their estimated useful lives to
their estimated residual values. SFAS No. 142

16

##### Table of Contents

became effective for fiscal years beginning after December 15, 2001. At March 31, 2003, other assets include approximately $20,172,000 of net goodwill, which was no longer
subject to amortization beginning in 2002.  There was no impairment of goodwill as of March 31, 2003.

Under the provisions of SFAS
No. 141, Business Combinations, we identified approximately $204,000 of intangible contract costs in connection with our acquisition of AquaSource and approximately $1,100,000 of intangible contract costs in connection with our acquisition of
OpTech. We are amortizing the intangible contract costs over a period of four years, which is the average estimated life of the contracts.

Utility Accounting:  Our regulated businesses, which include our utilities in California, New Mexico and Texas, are required to be accounted for under the
provisions of SFAS No. 71, which specifies certain revenue, expense and balance sheet treatment as required by each state regulatory agency.  Each state agency establishes rates which are intended to permit each utility to recover its costs and
earn a reasonable rate of return. Each utility may file and process general rate applications on a periodic basis.  Since the established rates may be in effect for several years, our utilities attempt to anticipate cost increases and apply for
rates sufficient to permit recovery of those cost increases when incurred.

One of the companies in our Services Group has
contracted with our utilities in Texas and New Mexico to perform operating services, normal maintenance and construction work, and, in addition, manage capital projects.  We believe that these contracts were established utilizing terms and
conditions equivalent to prevailing industry rates for similar work performed by our Services Group for non-affiliated entities.  In accordance with SFAS No. 71, our Services Group recognizes profit  from contract work performed and does
not eliminate the intercompany profit on the construction contract work performed when the contract sales price is reasonable and it is probable that the costs and capital will be recoverable through the rate making process.  Accordingly, the
intercompany profit on such projects has not been eliminated in the accompanying condensed consolidated financial statements.

Balancing Account:  Prior to November 29, 2001, the CPUC permitted California water utilities to record the difference between actual and CPUC-adopted
water production costs in balancing accounts on the balance sheet, with a corresponding adjustment in the income statement. In 2001, our water utility in California recorded approximately $700,000 of balancing account benefits in its income
statement, and had a total balance of approximately $2,300,000 in deferred costs held on its balance sheet at the end of November 2001.  No such benefits were available in 2002.  The disposition of pre-November 29, 2001 balancing accounts
became the subject of a CPUC rulemaking.  In December 2002, the CPUC issued a decision that we believe will allow our water utility in California to recover approximately $2,300,000 that was in its balancing account as of November 29,
2001.

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.  We believe that our allowance for doubtful accounts is adequate as of March 31,
2003.

Stock-Based Compensation: In 2002, we adopted the fair value recognition provisions of SFAS No. 123. SFAS No. 123 requires
that we value stock options issued based upon an option pricing model and recognize this value as an expense over the period in which the options vest. In accordance with the provisions of SFAS No. 148, we have elected to recognize stock-based
compensation using the retroactive restatement method.  Under this change in accounting method, we have restated our accompanying condensed consolidated financial statements for the prior period presented in the March Report

17

##### Table of Contents

to reflect stock-based compensation expense under a fair value based accounting method for all options granted, modified or settled in fiscal years beginning after December
15, 1994.

The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options that do not
have vesting restrictions and that are fully transferable.  In addition, option valuation models require us to make subjective assumptions including the expected future volatility of the stock price.  Because the stock options we grant
have characteristics that are significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the value of an estimate, in managements opinion, the existing option valuation
models, including Black-Scholes, do not necessarily provide a reliable single measure of the fair value of our employee stock options.

RISK FACTORS

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 2002 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 paid on the line of credit borrowings which is determined based upon an agreed rate formula with the banks. Contractually, the highest interest rates charged on the lines
of credit cannot exceed the banks prime rate minus one-quarter percent.

Southwest Water is utilizing 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 Southwest Water common stock and,
at a certain market price, our debentures will become dilutive in our computation of earnings per share.

Item 4. 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 the March Report.  Based upon that evaluation, our
certifying officers have concluded that the disclosure controls and procedures are effective in ensuring that all material information required to be filed in the March Report have been made known to them in a timely fashion. There have been no
significant changes in internal controls, or in factors that could significantly affect internal controls, subsequent to the date our certifying officers completed their evaluation.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

In April 2003, we filed a lawsuit
against the minority owner of Master Tek for certain misrepresentations and failure to disclose certain material facts. We are seeking indemnification for certain costs incurred subsequent to our purchase of the subsidiary in April 2000. In the
first quarter of 2003, the minority owner exercised an option to require us to purchase an additional 5% of Master Tek for $1,000,000. Because of the lawsuit, we placed the funds in an escrow account in accordance with the terms of the original
purchase agreement. These funds may be used to offset any final resolution of our claim. The minority owner intends to contest our lawsuit. We cannot predict the outcome of this lawsuit; however, we do not believe this action will have a material
adverse effect on our financial position, results of operations or cash flows.

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 in July 2000 at one of the facilities that we operate.  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 have denied any liability and are vigorously defending against the claim. Our  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 three
lawsuits alleging injury and damages as the result of a sewage spill which occurred at an Austin, Texas, sewage pumping station that we operate. A cross complaint was subsequently filed and served by the City of Brushy Creek, Texas. In 2001,
settlements were reached with three of the plaintiffs. The remaining lawsuit was settled in 2003.  We have been defended and indemnified by our insurance carrier and we were required to pay a $10,000 deductible on settlement in each of the
claims.

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.

Southwest Water and its subsidiaries are the subjects of certain litigation arising from the ordinary course
of operations. We believe the ultimate resolution of such matters will not materially affect our financial position, results of operations or cash flows.
