PROXY STATEMENT

QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIALS
AND THE ANNUAL MEETING

Q:: Why have I received these materials?
A:: The Company is providing these proxy materials for you, as a stockholder of Southwest Water, in connection with solicitation by our Board of Directors (the "Board") of proxies to be voted at our 2004 Annual Meeting of Stockholders and at any adjournment or postponement of that meeting. This Proxy Statement, form of proxy and voting instructions are being mailed on or about April 8, 2004.

You are invited to attend our Annual Meeting on May 13, 2004, at 10:00 a.m., Pacific Time. The Annual Meeting will be held at the Millennium Biltmore Hotel, 506 South Grand Avenue, Los Angeles, California. A map showing directions to the hotel is on the back cover of this Proxy Statement.

Q:: Who can attend the Annual Meeting?
A:: Our stockholders and Company representatives and guests can attend the meeting. Admission to the meeting depends on how your ownership of your shares is recorded. If your shares are held in the name of a bank, broker or other holder of record and you plan to attend the Annual Meeting, please obtain proof of ownership, such as a current brokerage account statement or certification from your broker. If your shares are registered with our transfer agent, all you need is proof of identification; no proof of ownership is needed.
Q:: Who is entitled to vote at this Annual Meeting?
A:: Owners of Southwest Water common stock or preferred Series A stock at the close of business on March 18, 2004, are entitled to receive this notice and to vote their shares at the Annual Meeting. As of that date, there were 14,804,393 shares of common stock outstanding and 9,327 shares of preferred Series A stock outstanding. On each matter properly brought before the Annual Meeting, common shares will be entitled to one vote per share, and preferred Series A shares will be entitled to five votes per share. The combined total number of eligible votes is 14,851,028 shares.
Q:: What is the quorum requirement for the Annual Meeting?
A:: The presence at the meeting, in person or by proxy, of the holders of a majority of the eligible votes on the record date will constitute a quorum, permitting the meeting to conduct its business. Proxies received, but marked as abstentions, and broker non-votes (i.e., shares that are not voted by the broker who is the record holder of the shares because the broker is not instructed to vote and does not have discretionary authority to vote such shares) will be included in the calculation of the number of votes considered to be present at the meeting.
Q:: What are the costs of proxy distribution and solicitation?
A:: Southwest Water will bear the entire cost of this solicitation of proxies, including the preparation, assembly, printing and mailing of this Proxy Statement, the proxy and any additional solicitation material that Southwest Water may provide to stockholders. Copies of solicitation material will be provided to brokerage firms, fiduciaries and custodians holding shares in their names that are beneficially owned by others so that they may forward the solicitation material to beneficial owners. In addition, Southwest Water has retained Morrow and Company ("Morrow") to act as a proxy solicitor for the meeting. Southwest Water has agreed to pay Morrow $5,000, plus reasonable out-of-pocket expenses, for proxy solicitation services. The original solicitation of proxies by mail may be supplemented by solicitation by telephone, telegram and other means by directors ("Director" or

"Directors"), officers and employees of Southwest Water. No additional compensation will be paid to these individuals for their services.

Q:

What information is contained in these materials?

A:

The information included in this Proxy Statement relates to the proposals to be voted on at the Annual Meeting, the voting process, the compensation of Directors and our most highly paid officers, and certain other required information. Southwest Water's 2003 Annual Report and audited financial statements, proxy card and return envelope are also enclosed.

Q:

What proposals will be voted on at the Annual Meeting?

A:

There are three proposals to be voted on at the Annual Meeting:

•: The election of three persons as Class III Directors for a three-year term or until their successors are duly elected and qualified;
•: Approval of an amendment to the Company's Amended and Restated Certificate of Incorporation increasing the number of authorized shares of common stock from 25,000,000 shares to 75,000,000 shares; and
•: Approval of an amendment to the Amended and Restated Stock Option Plan for Non-Employee Directors, which include an increase of 250,000 shares (from 437,555 shares to 687,555 shares) authorized for issuance under the plan, an increase of 5,000 shares to the initial and annual stock option grants to Non-Employee Directors (from 5,000 shares to 10,000 shares) and a four-year extension to the term of the plan to May 13, 2014.

Q:

What is Southwest Water's voting recommendation?

A:

Southwest Water's Board recommends that you vote your shares "FOR" each of the nominees to the Board, "FOR" the approval of an Amendment to the Amended and Restated Certificate of Incorporation and "FOR" the approval of the Amended and Restated Stock Option Plan for Non-Employee Directors.

Q:

What shares owned by me can be voted?

A:

Each share of Southwest Water stock issued and outstanding as of the close of business on March 18, 2004 (the "Record Date"), is entitled to vote on all items being voted upon at the Annual Meeting. You may cast one vote per share of common stock that you held on the Record Date. Holders of Series A Preferred Stock may cast five votes per share of preferred stock beneficially owned by them. You may vote all shares owned by you as of the Record Date, including shares that are: (1) held directly in your name as the stockholder of record or (2) held for you as the beneficial owner through a stockbroker, bank or other nominee.

Q:

What is the difference between holding shares as a stockholder of record and as a beneficial owner?

A:

Most stockholders of Southwest Water hold their shares through a stockbroker, bank or other nominee rather than directly in their own name. As summarized below, there are some distinctions between shares held of record and those owned beneficially.

Stockholder of Record

If your shares are registered directly in your name with Southwest Water's transfer agent, Mellon Investor Services LLC, you are considered the stockholder of record, and these proxy materials are being sent directly to you by Southwest Water. As the stockholder of record, you have the right to grant your voting proxy directly to Southwest Water or to vote in person at the Annual Meeting. Southwest Water has enclosed a proxy card for you to use. You may also vote by telephone as described below under "How can I vote my shares without attending the Annual Meeting?"

Beneficial Owner of Shares Held in Street Name

If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the beneficial owner of shares held in street name, and these proxy materials are being forwarded to you by your broker or nominee who is considered, with respect to those shares, the stockholder of record. As the beneficial owner, you have the right to direct your broker on how to vote and are also invited to attend the Annual Meeting. However, since you are not the stockholder of record, you may not vote these shares in person at the Annual Meeting unless you obtain a signed proxy from your broker. Your broker or nominee has enclosed a voting instruction card for you to use in directing the broker or nominee regarding how to vote your shares. You may also vote by telephone as described below under "How can I vote my shares without attending the Annual Meeting?"

Q:: How can I vote my shares in person at the Annual Meeting?
A:: Shares held directly in your name as the stockholder of record may be voted in person at the Annual Meeting. If you choose to do so, please bring the enclosed proxy card or proof of identification. Even if you plan to attend the Annual Meeting, Southwest Water recommends that you vote your shares in advance as described below so that your vote will be counted if you later decide not to attend the Annual Meeting.

Shares held beneficially in street name may be voted in person by you only if you obtain a signed proxy from the record holder (e.g., your broker) giving you the right to vote the shares in person.

Q:: How can I vote my shares without attending the Annual Meeting?
A:: If you complete and properly sign the accompanying proxy card and return it to the Company, it will be voted as you direct. If you are a registered stockholder, you may vote by telephone, by following the instructions included with your proxy card. If you hold shares beneficially in street name, you may vote by submitting voting instructions to your broker, trustee or nominee. For instructions on how to vote, please refer to the instructions below and those included on your proxy card or, for shares held beneficially in street name, the voting instruction card provided by your broker, trustee or nominee. The deadline for voting by telephone is 11:59 p.m., Eastern Time, on May 12, 2004.

By Telephone – Stockholders of record of Southwest Water stock who live in the United States or Canada may submit proxies by following the "Vote by Phone" instructions on their proxy cards. Most Southwest Water stockholders who hold shares beneficially in street name and live in the United States or Canada may vote by phone by calling the number specified on the voting instruction cards provided by their brokers, trustee or nominees.

By Mail – Stockholders of record of Southwest Water stock may submit proxies by completing, signing and dating their proxy cards and mailing them in the accompanying pre-addressed envelopes. Southwest Water stockholders who hold shares beneficially in street name may vote by mail by completing, signing and dating the voting instruction cards and providing and mailing them in the accompanying pre-addressed envelopes.

Q:

Can I change my vote?

A:

As a stockholder of record, you may revoke your proxy at any time before it is voted at the Annual Meeting by doing any of the following:

•: Delivering to the Secretary of the Company a signed notice of revocation, bearing a date later than the date of the proxy, stating that the vote is revoked;
•: Granting a new proxy, relating to the same shares and bearing a date later than the date of the earlier proxy; or

•: Attending the Annual Meeting and voting in person. However, attendance at the Annual Meeting will not, by itself, revoke your proxy.

If your shares are held in the name of a broker, bank or other nominee, you may change your vote by submitting new voting instructions to your bank, broker or other record holder. You must contact your bank, broker or other record holder to find out how to do so.

Please note that if your shares are held of record by a broker, bank or other nominee, and you decide to attend and vote at the Annual Meeting, your vote in person at the Annual Meeting will not be effective unless you have obtained and present a proxy issued in your name from the record holder, your broker.

Written notices of revocation of proxies should be addressed to:

Southwest Water Company
c/o Secretary
One Wilshire Building
624 South Grand Avenue, Suite 2900
Los Angeles, CA 90017

Q:: How are votes cast?
A:: In the election of Directors, you may vote "FOR" all of the nominees or your vote may be "WITHHELD" with respect to one or more of the nominees. For all other proposals, you may vote "FOR," "AGAINST" or "ABSTAIN" on each such proposal. If you "ABSTAIN" it has the same effect as a vote "AGAINST." If you sign your proxy card or broker voting instruction card with no further instructions, your shares will be voted in accordance with the recommendations of the Board.
Q:: What is the voting requirement to approve each of the proposals?
A:: For Item One, the three nominees receiving the highest number of affirmative votes of the outstanding shares of the Company's securities, present or represented by proxy and entitled to vote, shall be elected as Directors to serve until their successors have been elected and qualified. The election of Directors is a matter on which a broker or other nominee is generally empowered to vote, and therefore, no broker non-votes will likely exist in connection with Item One.

Approval of Item Two requires an affirmative vote of a majority of the outstanding shares of the Company's securities entitled to vote on the Item. Approval of Item Three required an affirmative vote of a majority of the outstanding shares of the Company's securities, present or represented by proxy and voting on the proposal. If you are a beneficial owner and do not provide the stockholder of record with voting instructions, your shares may constitute broker non-votes, as described in "What is the quorum requirement for the Annual Meeting." Brokers are authorized to vote on Item Two; thus, broker non-votes likely will not have any effect on Item Two. Brokers, however, are not authorized to vote on Item Three. Thus, broker non-votes may result, but since they are not considered a vote on the proposal they will not have any effect on the outcome of Item Three. Abstentions will count as a vote against Item Two, but will have no effect on Item Three.

Q:: What does it mean if I receive more than one proxy or voting instruction card?
A:: It means your shares are registered differently or are in more than one account. Please provide voting instructions for all proxy and voting instruction cards you receive.
Q:: Who will serve as inspector of election?
A:: The inspector of election will be a representative of Mellon Investor Services, LLC.

Q:: What documents are incorporated by reference?
A:: The Report of the Compensation Committee of the Board on Executive Compensation, the Audit Committee Report (including reference to the independence of the Audit Committee members) and the Stock Price Performance Graph, are not deemed filed with the SEC and shall not be deemed incorporated by reference into any prior or future filings made by the Company under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, except to the extent that the Company specifically incorporates such information by reference.
Q:: Where can I find the voting results of the Annual Meeting?
A:: Southwest Water intends to announce preliminary voting results at the Annual Meeting and publish final results in our quarterly report on Form 10-Q for the second quarter of fiscal 2004.

Identifying and Evaluating Nominees for Directors

The Nominating and Governance Committee uses a variety of methods to identify and evaluate nominees for Director, including materials provided by professional search firms or other parties.

The Board shall nominate the Director candidates it deems most qualified for election by the stockholders. In accordance with the bylaws of the Company, the Board will be responsible for filling

vacancies or newly created directorships on the Board that may occur between annual meetings of stockholders.

EXECUTIVE COMPENSATION

Report of the Compensation Committee

Executive Officer Compensation Philosophy

The compensation philosophy for executive officers is to ensure that compensation is directly linked to continuous improvements in the Company's financial performance and stockholder value. To implement this philosophy, the Committee is guided by the following objectives: (1) enable the Company to attract and retain highly qualified executives, (2) focus executives' efforts on the fulfillment of Company annual and long-term business objectives and strategies, and (3) ensure that a portion of executive compensation is tied to specific performance measures. The Committee has retained outside consultants and executive compensation specialists in evaluating and modifying the current executive compensation plan.

Executive Compensation

In determining the base salary levels of executives, including the chief executive officer, the Committee considers individual performance, the performance of the operations directed by the executive, and the competitive salary levels of executives in companies of similar size and complexity. Competitive salary information, obtained primarily through published compensation surveys, is used to determine the reasonableness of total compensation, which includes base salary and incentive compensation. For executives other than the chief executive officer, the Compensation Committee also considers the recommendations of the Chief Executive Officer.

Annual Incentive Compensation

The Committee believes that the Company's short-term objectives are enhanced with annual performance-based incentive compensation for its executives. Annual incentive awards are based on the attainment of meeting certain financial objectives for the Company and on an executive's achievement of goals in his or her area of functional responsibility. Executive performance objectives include both quantitative and qualitative criteria. As an executive's level of responsibility increases, a greater portion of potential total cash compensation is at risk in the form of annual performance-based incentives.

The Compensation Committee establishes financial goals and performance-based measures at the beginning of each year. Awards are made at the end of the year based on actual performance. Each year, the Committee establishes performance objectives. No awards are made if performance objectives are not attained. In 2003, in those areas where the actual results for the year met or exceeded the objectives set by the Committee, incentive compensation awards were approved for the Company's executives.

Long-term Incentive Compensation

The primary purpose of long-term incentives is to encourage and facilitate long-term Company performance by greater personal stock ownership by the executive officers and thus strengthen both their personal commitments to the Company and a longer-term perspective in their managerial responsibilities. This component of an executive officer's compensation directly links the officer's interests with the Company's long-term goals and with the interests of the Company's other stockholders. Currently, the primary form of long-term incentive compensation is non-qualified stock options. The Compensation Committee approves stock options for all executives and managers.

In determining the number of stock options awarded, the Compensation Committee considers a number of factors including the executive's pay level, responsibilities in the organization, and ability to significantly improve future financial results. In addition, the Compensation Committee compares the Company's option grant levels with similar industry practices.

Chief Executive Officer Compensation

Anton C. Garnier has been chief executive officer of the Company since November 1968, and has been Chairman of the Board since August 1996. The Committee reviewed Mr. Garnier's 2003 performance based on the performance of the Company as a whole and his performance with respect to quantitative and qualitative objectives approved at the start of the year by the Committee. The Committee carefully considered the Company's continuing improvements in short-term and long-term financial results, including earnings improvement, new business development, management development, return on equity and the creation of stockholder value. The Committee also evaluated Mr. Garnier's progress in attaining qualitative objectives in such areas such as investor relations, planning for the Company's long-term future, setting strategic objectives, and employee involvement and communications. The Committee did not use specific weighting factors with respect to quantitative and qualitative performance measures.

In evaluating Mr. Garnier's performance for 2003, the Committee gave particular emphasis to the Company's consistent earnings while continuing to provide attractive shareholder returns during a challenging year, as well as positioning the Company for the future. After the Committee's deliberations, the Committee increased Mr. Garnier's annual salary from $350,000 to $367,500, effective January 1, 2004, and awarded him an incentive compensation amount of $198,750 for 2003. In addition, on February 11, 2004, the Committee awarded Mr. Garnier a stock option grant of 75,000 shares of the Company's common stock in recognition of the Company's long-term performance.

Executive Officers' Change of Control Compensation Agreements

In 1998, Messrs. Garnier and Moerbeek entered into change of control compensation agreements with the Company, and in 2001 and 2002, Messrs. Monette and Shields, respectively, entered into similar change of control agreements. The Company has agreed to provide benefits and payments to Messrs. Garnier, Moerbeek, Monette and Shields based on 2.99 times their respective average five-year compensation if certain conditions are met.

In 1995, Mr. Quinn entered into a change of control compensation agreement with the Company. Under this agreement, the Company has agreed to provide severance benefits and payments to Mr. Quinn based on 1.5 times his average five-year compensation if certain conditions are met.

For the purpose of these agreements, a "change in control" is generally defined as a change in the person or persons owning, directly or indirectly, sufficient voting stock to elect the Board for the entity that employs an executive. These compensation agreements are in addition to the plans described under the heading "Supplemental Executive Retirement Plan."

The agreements for Messrs. Garnier, Moerbeek, Monette, Shields and Quinn will be triggered if there is a change of control and either of the following conditions is met: (1) termination of the executive's employment by his employer prior to the second anniversary of a change in control, other than termination by retirement or for death, disability or cause; or (2) termination of executive's employment by the executive within two years after a change in control for "good reason" (including assignment of executive to duties inconsistent with executive's position, duties, responsibilities and status prior to the change in control or, alternatively, a reduction in salary, a significant reduction in benefits, an elimination of stock plans or a relocation of employment greater than 50 miles). Under these agreements, cash severance payments are based upon base salary, auto benefits, bonuses and certain life insurance premium amounts paid by the employer. Cash severance payments are payable within five days after termination of employment. Cash severance amounts as of December 31, 2003, assuming termination met the requirements for a severance payment are as follows: Mr. Garnier – $1,460,481; Mr. Moerbeek—$1,037,022; Mr. Monette – $632,551, Mr. Shields – $535,647 and Mr. Quinn – $351,816. In addition to the cash payment, each executive is entitled to certain health insurance benefits with a value of approximately $25,000, and outplacement services with a maximum benefit of $15,000 each for Messrs. Garnier, Moerbeek, Monette and Shields, and $4,000 for Mr. Quinn. These payments and benefits are subject to certain Internal Revenue Service limitations and may be reduced if these limitations are met.

Option Grants to Named Executive Officers in 2003

The following table sets forth information regarding stock option grants under Southwest Water's Stock Option Plan during the fiscal year ended December 31, 2003, to the named executive officers. The amounts shown for each named executive officer as potential realizable values are based entirely on assumed annualized rates of stock price appreciation of 5% and 10% over the full term of the options. These assumed rates of growth were selected by the SEC for illustration purposes only and are not intended to predict future stock price, which will depend on overall performance and prospects. Consequently, there can be no assurance that the potential realizable values shown in this table will be achieved.

(1): Options vest 20% per year until fully vested. The options were granted for a term of seven years and one day, subject to earlier cancellation upon certain events related to termination of employment. The exercise price and tax withholding obligations related to exercise may be paid by delivery of already owned shares or by offsetting the underlying shares, subject to certain conditions.
(2): All exercise prices represent fair market value on the date of grant and reflect a 4 for 3 stock dividend on January 1, 2004.
(3): Potential realizable values are based on assumed annual rates of return specified by the SEC. Southwest Water's management has consistently cautioned stockholders and option holders that such increases in values are based on speculative assumptions and should not inflate expectations of the future value of their holdings.

Options Exercised in 2003 and Year-End Option Values

The following table shows information on exercised and unexercised stock options, value realized and the value of unexercised options during the Company's most recent fiscal year for the chief executive officer of the Company and the other named executive officers.

Supplemental Executive Retirement Plan

The Southwest Water Company Supplemental Executive Retirement Plan (the "SERP") was adopted by Southwest Water Company effective May 8, 2000. Two executive officers of the Company have been selected by the Compensation Committee as participants in the SERP: Messrs. Garnier and Moerbeek. Under the SERP, in most cases, a vested participant with five to 10 years of service will be eligible for a yearly benefit for his or her lifetime beginning at age 65 equal to: the participant's average annual compensation multiplied by the applicable compensation percentage as defined by the SERP, less (1) the Social Security benefit for the most recent five years of employment and less (2) benefits received under the Company-sponsored Noncontributory Defined Benefit Pension Plan, which was terminated effective December 30, 1999.

The following table shows the estimated annual benefits that would be payable to participants in the SERP at age 65.

5-Year Average Annual Compensation $	Estimated Annual Benefit for Years of Service Indicated $
	15 Years	25 Years	35 Years
200,000	21,100	15,200	24,400
240,000	33,100	35,200	52,400
280,000	45,100	55,200	80,400
320,000	57,100	75,200	108,400

The compensation used in determining final average compensation under the SERP is the participant's base salary and excludes bonuses and other forms of compensation.

On December 31, 2003, the base compensation for the participating officers was: Anton C. Garnier – $350,000 and Peter J. Moerbeek – $251,500. Their years of credited service were 34 and nine, respectively. The SERP is an unfunded plan. The Company, however, has invested in a corporate-owned life insurance policy to assist in funding the Company's obligations under the SERP.

AUDIT RELATED MATTERS

Report of the Audit Committee

The Audit Committee of the Board of Directors is composed of four independent directors, in compliance with the listing standards of the NASDAQ Stock Market and the SEC rules. The Audit Committee operates under a written charter adopted by the Board of Directors.

The Board of Directors has adopted a written charter setting forth the audit-related functions the Audit Committee is to perform. The Audit Committee reviewed this charter in March 2004. A copy of the charter is attached to this 2004 Proxy Statement.

The Audit Committee is responsible for overseeing the Company's financial reporting process on behalf of the Board of Directors. Management of the Company has the primary responsibility for Southwest Water's financial reporting process, internal controls, and compliance with laws and regulations and ethical business standards. The independent auditors are responsible for performing an audit of the Company's consolidated financial statements in accordance with generally accepted auditing standards and issuing an opinion as to the conformity of such financial statements with accounting principles generally accepted in the United States.

In the context stated above, the Audit Committee has met and held separate discussions with management and with our independent auditors, KPMG LLP. Management has represented to the Audit Committee that the Company's consolidated financial statements were prepared in accordance with generally accepted accounting principles, and the Audit Committee has reviewed and discussed the consolidated financial statements with management and the independent auditors. The Audit Committee also discussed with the independent auditors matters required to be discussed by Statement on Auditing Standards No. 61 "Communication with Audit Committees."

Southwest Water's independent auditors also provided to the Audit Committee the written disclosures and the letter required by Independence Standards Board Standard No. 1 "Independence Discussions with Audit Committees." The Audit Committee has considered whether the independent auditors' provision of non-audit services to the Company is compatible with maintaining the auditors' independence. The Audit Committee has concluded that the independent auditors are independent from the Company and its management.

Based upon the Audit Committee's review and discussions referred to above, the Audit Committee has recommended to the Board of Directors that the Company's audited consolidated financial statements be included in its Annual Report on Form 10-K for the year ended December 31, 2003, for filing with the Securities and Exchange Commission.

All Other Fees: No other fees were paid for 2003 or 2002 services by KPMG LLP.

Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of Independent Auditors

The Audit Committee pre-approves all audit and non-audit services provided by the independent auditors. The Audit Committee has adopted a policy regarding the pre-approval of services provided by the independent auditors. Under the policy, pre-approval is detailed as to the particular service or category of services and is subject to a specific budget. The Audit Committee may delegate pre-approval authority to one or more of its members.

Complaint Procedure

The Sarbanes-Oxley Act of 2002 requires companies to maintain procedures to receive, retain and treat complaints received regarding accounting, internal accounting controls or auditing matters and to allow for the confidential and anonymous submission by employees of concerns regarding questionable accounting or auditing matters. We currently have such procedures in place. Our 24-hour, toll-free confidential compliance line is available for employees to submit concerns regarding accounting, internal control or auditing matters.

ITEM 2 – TO AMEND THE COMPANY'S RESTATED CERTIFICATE OF INCORPORATION
TO INCREASE THE NUMBER OF AUTHORIZED SHARES FROM
25,000,000 SHARES TO 75,000,000 SHARES

The stockholders are asked to approve an amendment to the Company's Restated Certificate of Incorporation (the "Restated Certificate") to increase the number of authorized shares of the Company's common stock from 25,000,000 shares to 75,000,000 shares. The Board has determined that the amendment is in the best interests of the Company and its stockholders and unanimously recommends approval by the stockholders. As of March 18, 2004, 14,804,393 shares of the Company's common stock were outstanding and 2,884,170 shares of the Company's common stock were available for issuance under stock option, employee benefit, and dividend reinvestment plans.

The Company's Board believes that it is in the best interests of the Company and its stockholders to amend the Restated Certificate in order to have available additional authorized but unissued shares of common stock in an amount adequate to provide for the future needs of the Company. The additional shares will be available for issuance from time to time by the Company at the discretion of the Board, subject to stockholder approval as may be required under applicable law or exchange regulations. The Company filed an S-3 registration statement with the SEC on December 29, 2003, and anticipates that it may potentially issue additional shares of common stock for capital-raising purposes. In addition, the Company has issued stock dividends in each of the years 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003 and 2004, and will continue to address the advisability of issuing additional stock dividends in the future.

The additional common stock to be authorized by adoption of the amendment would have rights identical to the common stock of the Company. The increase in authorized common stock will not have any immediate effect on the rights of existing stockholders, except for effects incidental to increasing the number of shares of the common stock outstanding, such as dilution of the earnings per share and voting rights of current holders of common stock. If the amendment is adopted, it will become effective upon the filing of a Certificate of Amendment to the Restated Certificate with the Secretary of State of the State of Delaware. The full text of the amendment to Article Four, Section A of the Restated Certificate is set forth in Appendix B.

The increase in the number of authorized shares of common stock could have an anti-takeover effect, although this is not the intent of the Board in proposing the amendment. For instance, the Company's authorized but unissued common stock could be issued in one or more transactions that would make a takeover of the Company more difficult or costly, and less likely. As of the date of this Proxy Statement, the Board is not aware of any attempt or plan to obtain control of the Company.

Required Vote

The affirmative vote of a majority of the outstanding shares of the Company's securities entitled to vote on the proposal, is required for approval of the amendment to the Restated Certificate increasing the number of authorized shares of common stock to 75,000,000 shares. Abstentions on this proposal will have the effect of a vote against the Item. Brokers are authorized to vote on this proposal, thus no broker non-votes will likely result.

Board Recommendation

THE BOARD OF DIRECTORS RECOMMENDS THE STOCKHOLDERS VOTE FOR APPROVAL OF THIS ITEM 2 TO AMEND THE COMPANY'S RESTATED CERTIFICATE OF INCORPORATION TO INCREASE THE NUMBER OF AUTHORIZED SHARES OF COMMON STOCK FROM 25,000,000 SHARES TO 75,000,000 SHARES.

ITEM 3 – APPROVAL OF AN AMENDMENT TO THE AMENDED AND RESTATED STOCK OPTION PLAN FOR NON-EMPLOYEE DIRECTORS OF SOUTHWEST WATER COMPANY

The Company's stockholders are being asked to approve an amendment to the Amended and Restated Stock Option Plan for Non-Employee Directors (the "Amended Director Plan"), which amendment provides as follows:

•: Authorizes an additional 250,000 shares for issuance under the plan, increasing the authorized number of shares from 437,555 to 687,555 shares;
•: Increases the initial automatic grant and annual automatic grant of stock option awards from 5,000 to 10,000 shares per Non-Employee Director;
•: Extends the plan termination date from May 23, 2010, to May 13, 2014; and
•: Provides that the anti-dilution adjustments for stock splits and dividends provided by the Amended Director Plan will apply to the 10,000 automatic option grants to be in effect following adoption of the proposed amendment of the Amended Director Plan.

The proposed amendment was unanimously adopted by the Board on February 12, 2004, and would become effective upon stockholder approval at the Annual Meeting. A full text of the proposed amendment is attached as Appendix C.

As of March 18, 2004, 172,461 shares remain available for grant under the Amended Director Plan, without giving effect to the amendment. The Board believes that the increase in shares available for issuance is necessary to establish a reserve of shares that would enable the grant of stock to Non-Employee Directors. In addition, the Board believes that the Amended Director Plan is necessary to ensure that the Company will continue to retain, motivate and attract qualified Non-Employee Directors.

The following is a summary of the principal features of the Amended Director Plan. The summary, however, is not a complete description of all the provisions of the Amended Director Plan. Any stockholder of the Company who wishes to obtain a copy of the plan document may do so upon written request to the Secretary at the Company's principal executive offices at One Wilshire Building, 624 South Grand Avenue, Suite 2900, Los Angeles, California 90017.

General Nature of the Amended Director Plan

The Amended Director Plan authorizes the grant of non-qualified stock options to our Non-Employee Directors. The principal purposes of the Amended Director Plan are to provide incentives to Non-Employee Directors of the Company to further the growth, development and financial success of the Company by personally benefiting through the ownership of Company stock, and to obtain and retain the services of Non-Employee Directors who are considered essential to the long-range success of the Company. The approval by stockholders of the Amended Director Plan will allow us to continue to align interests of Directors with the stockholders of the Company.

Shares Reserved

Under the Amended Director Plan, the total number of shares of common stock that could be issued is 687,555, including the 250,000 share increase for which stockholder approval is sought under this proposal. After giving effect to the increase, 422,461 shares will remain available for future grant under the Amended Director Plan.

The shares of common stock available for issuance under the Amended Director Plan may be either previously authorized and unissued shares or treasury shares. The Amended Director Plan provides for adjustments in the number and kind of shares subject to the Amended Director Plan and to outstanding options in the event of a stock split, stock dividend and certain other types of transactions. Available for

issuance under the Amended Director Plan are (i) shares subject to expired, exchanged or canceled options; and (ii) shares delivered by the optionee or withheld by the Company in payment of the exercise price or any related tax withholding obligation.

Administration

The Amended Director Plan is administered by the Board, which has the full authority to adopt rules for the administration, interpretation and application of the Amended Director Plan.

Automatic Option Grants

The Amended Director Plan provides for automatic grants to non-employee directors of non-qualified stock options as follows:

•: Each person who is a Non-Employee Director as of the 2004 Annual Meeting of Stockholders will automatically be granted on the date of the 2004 Annual Meeting of Stockholders an option to purchase 10,000 shares of common stock; and
•: Additionally, each person who first becomes a Non-Employee Director after the 2004 Annual Meeting of Stockholders by election or appointment to the Board shall be granted automatically on the date of such person's election or appointment to the Board an initial option to purchase 10,000 shares of common stock.

Thus, assuming they continue as Non-Employee Directors following the 2004 Annual Meeting of Stockholders, Messrs. Castle, Christie, Huennekens, and Newman and Mss. Griego and Kindel will, if this proposal is approved by the stockholders, each be granted an option covering 10,000 shares on the date of this Annual Meeting.

Each option and its exercise price, term, vesting and other material terms are evidenced by a written stock option agreement.

Exercise Price

The exercise price of each option granted under the Amended Director Plan is equal to the last sales price of our common stock on the NASDAQ Stock Market on the day prior to the date of grant. On March 18, 2004, the average of the last sales price of a share of our common stock on the NASDAQ Stock Market was $14.47.

Vesting of Options

An option may be exercised when and to the extent it "vests." The options vest 50% on the first anniversary of the grant date and 50% on the second anniversary of the grant date. In addition, the options become fully vested upon termination of the optionee's service as a Director of the Company after the first anniversary of the option grant date.

Term and Termination of Options

The term of each option is seven years and one day from the date of grant. In the event of the termination of the optionee's service as a Director of the Company, the optionee (or the optionee's representative) may exercise the option at any time before the earliest of:

•: one year following termination;
•: one year following the death of optionee; or
•: seven years and one day following the option grant date.

Exercise of Options

An option may be exercised for any vested portion of the shares subject to the option unless the option expires or terminates. Only whole shares may be purchased upon exercise.

An option may be exercised by delivering to the Company a written notice of exercise, together with payment of the aggregate exercise price in the form of cash or a check payable to the Company. The Board may, however, in its discretion allow payment through:

•: the delivery of shares of our common stock already owned by the optionee, subject to certain minimum ownership requirements;
•: the surrender of shares of our common stock that would otherwise be issuable on exercise of the option; or
•: the delivery of a notice that the optionee has placed a market sell order with a broker with respect to shares of common stock issuable upon exercise of the option, and the broker timely pays a sufficient portion of the net proceeds of the sale to the Company in satisfaction of the option exercise price.

An optionee will not have any rights as a stockholder until the Company has issued and delivered the shares of common stock following option exercise. The Company will not adjust the option shares for dividends or distributions if the record date for the dividend or distribution is prior to the date of such stock issuance.

Options Not Transferable

An optionee cannot assign or transfer any option, except:

•: by will or the laws of descent and distribution;
•: pursuant to a qualified domestic relations order; or
•: with permission from the Board, to certain family members and family trusts.

Plan Amendment and Termination

The Board may not, without prior stockholder approval:

•: change the total number of shares of stock that may be issued under the Amended Director Plan; or
•: amend the Amended Director Plan in a manner that requires stockholder approval under any applicable law.

All other amendments may be made by the Board without stockholder approval. The Amended Director Plan will be in effect until May 13, 2014.

Adjustment in Securities

If there is a dividend, recapitalization, reclassification, stock split, merger, consolidation, split-up, spin-off, combination, consolidation, dissolution or other similar corporate transaction that affects the common stock, the Board may appropriately adjust:

•: the aggregate number of shares of common stock subject to the Amended Director Plan;
•: the number of shares of common stock subject to outstanding options;
•: the price per share of outstanding options; and

•: the number of options automatically granted under the Amended Director Plan (thus, if there is a stock split or dividend, the 10,000 shares automatically granted initially and annually may be adjusted).

In addition, if there is a merger of the Company, the sale of all or substantially all of the Company's assets or 80% or more of the Company's voting stock, or the dissolution or liquidation of the Company, the Board may provide in the option agreement or in a resolution that the options may be exercisable as to all shares covered by the option, and/or may provide for the assumption of the option by the successor corporation.

Federal Income Tax Consequences

The following summarizes federal income tax consequences of the Amended Director Plan under current federal income tax law and is intended for general information only. Other federal taxes and foreign, state and local income taxes are not discussed, and may vary depending on individual circumstances and from locality to locality.

For federal income tax purposes, optionees granted non-qualified stock options will not have taxable income on the grant of the option, nor will the Company then be entitled to any deduction. Generally, upon exercise of non-qualified stock options the optionee will realize ordinary income, and the Company will be entitled to a deduction, in an amount equal to the difference between the option exercise price and the fair market value of the common stock on the date of exercise. The optionee's basis for the stock for purposes of determining gain or loss on subsequent disposition of such shares generally will be the fair market value of the common stock on the date of option exercise. Any subsequent gain or loss will be generally taxable as capital gains or losses.

Required Vote

The affirmative vote of a majority of the outstanding shares of the Company's securities, present or represented by proxy and voting on the proposal is required for approval of the amendment to the Amended and Restated Stock Option Plan for Non-Employee Directors. Abstentions on this proposal will not be counted for purposes of determining the total number of shares that voted on the proposal and thus will not have an effect on the outcome of this proposal. Broker non-votes are not considered a vote for purposes of determining whether stockholder approval of this proposal has been obtained and therefore will not have an effect on the outcome of this proposal.

Board Recommendation

THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR APPROVAL OF THIS ITEM 3 TO AMEND THE AMENDED AND RESTATED STOCK OPTION PLAN FOR NON-EMPLOYEE DIRECTORS.

REQUIREMENTS, INCLUDING DEADLINES, FOR SUBMISSION OF PROXY PROPOSALS, NOMINATION OF DIRECTORS AND OTHER BUSINESS OF STOCKHOLDERS

The Company anticipates holding its 2005 Annual Meeting of Stockholders on May 12, 2005. Stockholder proposals (including nomination of a person for election to the Board of Directors) to be included in the proxy statement for the 2005 Annual Meeting must be received by the Company's Secretary not later than December 10, 2004. For proposals to be included, you must comply with the rules of the SEC governing the submission of stockholder proposals.

Under our bylaws, no business may be brought before an Annual Meeting unless it is specified in the notice of the meeting or is otherwise brought before the meeting by a stockholder entitled to vote who has delivered notice to the Company (containing certain information specified in the bylaws) not less than 90 days prior to the scheduled Annual Meeting. If a stockholder commences his or her own proxy solicitation for the 2005 Annual Meeting or seeks to nominate a candidate for election or propose business for consideration at such meeting, the Company must receive notice of such proposal no later than February 12, 2005. If the notice is not received by such date, it will be considered untimely under the Company's bylaws, and the Company will have discretionary voting authority under proxies solicited for the 2005 Annual Meeting with respect to such proposal, if presented at the meeting. These requirements are separate from and in addition to the SEC's requirements that the stockholder must meet in order to have a stockholder proposal included in the Company's Proxy Statement.

All proposals should be submitted in writing to the Company's Secretary, One Wilshire Building, 624 South Grand Avenue, Suite 2900, Los Angeles, California 90017.

By order of the Board of Directors,
