                               PROXY STATEMENT
                               ---------------

Proxy Delivery
  You are receiving these proxy materials in connection with the solicitation by
the Board of Directors of Southwest Water Company, a Delaware corporation,
("Southwest Water," the "Company," "we" or "us"), of proxies to be voted at our
2001 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 12, 2001.
  You are invited to attend our Annual Meeting of Stockholders (the "Annual
Meeting") on May 22, 2001, beginning at 10:00 a.m., Pacific time.  The Annual
Meeting will be held at the Omni Los Angeles Hotel at California Plaza, 251
South Olive Street, Los Angeles, California.

Annual Meeting Admission
  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. Admission to the Annual Meeting depends on your physical proof of
ownership.  If your shares are registered with our transfer agent, they will
provide your proof of ownership prior to the Annual Meeting.

Stockholders Entitled to Vote
  Owners of Southwest Water Company common or preferred Series "A" stock at the
close of business on March 30, 2001, are entitled to receive this notice and to
vote their shares at the Annual Meeting.  As of that date, there were 8,579,638
shares of common stock outstanding and 10,288 shares of preferred Series "A"
stock outstanding.  Common shares are entitled to one vote per share, and
preferred Series "A" shares are entitled to five votes per share on matters
properly brought before the Annual Meeting. The combined total number of
eligible votes is 8,631,078.

Proxies
  Your vote is important so we can have a valid meeting.  The proxy card that
accompanies this proxy statement will give you voting instructions.  Please
review the enclosed proxy materials and vote as soon as possible. Proxies may be
changed or revoked at any time before the Annual Meeting by:
(1) written notice to the Secretary of the Company,
(2) timely delivery of a later-dated proxy, or
(3) voting by ballot at the Annual Meeting.
  You can save us the expense of a second mailing by voting promptly.  Choose
one of the following voting methods to cast your vote, unless you are instructed
differently:

1. Vote by Telephone
     If your shares are registered in your name with Mellon Investor Services
  LLC, our transfer agent, you can vote your shares by telephone by calling the
  toll-free telephone number on your proxy card.  Telephone voting is available
  24 hours a day.  Have your proxy card with you when you place your call.  If
  you vote by telephone, you do not need to return your proxy card.

2. Vote by Mail
     If you choose to vote by mail, simply mark your proxy, date and sign it,
  and return it in the postage-paid envelope provided.  If your shares are
  registered with our transfer agent, and if you wish to discontinue future
  duplicate mailings, check the box provided on the card.

                                       1


Voting at the Annual Meeting
  The method by which you vote a proxy will not limit your right to vote at the
Annual Meeting if you decide to attend in person.  If your shares are held in
the name of a bank, broker or other agency and you plan to attend the Annual
Meeting, please bring proof of ownership, such as a current brokerage account
statement or certification from your broker.

  All shares that have been properly voted - whether by telephone or mail - and
not revoked will be voted at the Annual Meeting in accordance with your
instructions.  If you sign your proxy card but do not give voting instructions,
the shares represented by your proxy will be voted as recommended by the Board
of Directors.

Voting On Other Matters
  If any other matters are properly presented for consideration at the Annual
Meeting, the persons named in the enclosed form of proxy will have the
discretion to vote on those matters for you.  At the date of this proxy
statement, we do not know of any other matters to be raised at the Annual
Meeting.

List of Stockholders
  A list of stockholders who have shares registered in their own name and are
entitled to vote will be available at the Annual Meeting.

Quorum
In order to carry on the business of the Annual Meeting, there must be a quorum.
This means at least a majority of the outstanding shares entitled to vote (with
each share of preferred stock counting as five votes for every share owned for
purposes of the quorum) must be represented at the Annual Meeting, either by
proxy or in person.  Abstentions and broker "non-votes" will be counted as
present and entitled to vote for purposes of determining a quorum.  Broker "non-
votes" are shares held by a broker, which are represented at the meeting, but as
to which the broker is not empowered to vote on a particular proposal.

Required Vote for Passage
  ITEM 1.  The three nominees receiving the most votes will be elected as
Directors.  Abstentions and broker "non-votes" are not counted for purposes of
the election of Directors.

  ITEM 2.  The favorable vote of a majority of the votes cast is required to
ratify the appointment of KPMG LLP as the Company's independent auditors for
2001.  Abstentions and broker "non-votes" will not be counted as votes for or
against the proposal.

Cost of Proxy Distribution and Solicitation
  We will pay the expenses of distributing the proxy materials and soliciting
proxies.  Proxies may be solicited on our behalf by Directors, officers or
employees, in person or by telephone, electronic transmission or by facsimile
transmission.  Mellon Investor Services will distribute the proxy materials to
our registered stockholders and, through a search process, obtain information to
distribute these materials to our stockholders whose shares are held by a bank,
broker or other agency.

Section 16(a) Beneficial Ownership Reporting Compliance
Section 16(a) of the Securities Exchange Act of 1934 requires our Directors,
executive officers and beneficial owners of more than 10% of our common stock to
file reports of holdings and transactions in Southwest Water shares with the SEC
and the Nasdaq Stock Market.  Based on our records and other information, we
believe that in 2000 all of our Directors and executive officers met all
applicable SEC Section 16(a) filing requirements.  Our records indicate that we
do not have any beneficial owners of more than 10% of the Company's common
stock.

                           GOVERNANCE OF THE COMPANY

                      Our Corporate Governance Principles

                 Role and Composition of the Board of Directors

1.  The Board of Directors, which is elected by the stockholders, is the
    ultimate decision-making body of the Company, except with respect to those
    matters reserved to the stockholders. The Board selects the senior
    management team which is charged with the conduct of the Company's business.
    Having selected the senior management team, the Board acts as an advisor and
    counselor to senior management and monitors its performance.

2.  It is a policy of the Company that the Board consist of a majority of
    outside Directors and that the number of Directors not exceed a number that
    can function efficiently as a body. The Nominating Committee, in
    consultation with the Chairman and CEO, considers and makes recommendations
    to the Board concerning the appropriate size and needs of the Board. The
    Nominating Committee considers candidates to fill new positions created by
    expansion and vacancies that occur by resignation, retirement or any other
    reason. Candidates are selected for their character, judgment, business
    experience and acumen. Final approval of a candidate is determined by the
    full Board. All Directors are expected to be stockholders. The Company's
    current Directors are listed below.

    Non-Employee Directors:  H. Frederick Christie, Monroe Harris,
    ----------------------
                             Donovan D. Huennekens, Maureen A. Kindel
                             and Richard G. Newman.

    Employee Directors:      Anton C. Garnier, Chairman and CEO and
    ------------------

                             Secretary

3.  Mr. Richard Kelton, who served as a Director for over 30 years, stepped down
    in March 2001, and will not stand for reelection. At the April 11, 2001,
    Board meeting, Mr. Moerbeek was appointed to fill his position.

4.  The Chairman and CEO is responsible for establishing effective communication
    with the Company's stockholders and Board members.

   Meeting Fees.  Non-employee Directors also receive a fee of $1,000 for
attending each Board meeting, committee meeting and long-range planning meeting.
When a committee meeting is held on the same day as a Board meeting, the
committee attendance fee is $500.

  Directors who are officers of the Company are not paid any fees or additional

  Director Stock Option Plan.  The Director Stock Option Plan provides that non-
employee Directors are automatically granted an initial award of 5,000 shares of
the Company's common stock when they become Directors, and each active Director
is also automatically granted an annual award of 5,000 shares of the Company's
common stock at each subsequent Annual Meeting.

Southwest Water Company Board past his or her 72nd birthday.  Mr. Harris, over
the age of 72 at the time the policy was implemented, will serve until January
2002.

                   COMPARISON OF THE CUMULATIVE TOTAL RETURN
          ON THE COMPANY'S COMMON STOCK TO CERTAIN INDUSTRY STANDARDS

   The following graph compares the cumulative total return to holders of the
common stock of the Company during the most recent five fiscal years versus the
average return to investors during the same period achieved by 12 publicly held
water utilities listed in the Edward Jones Water Utility Index and that achieved
by The Standard and Poor's Index of 500 Companies.  The comparison assumes that
$100 was invested on December 31, 1995, and the cumulative total return assumes
the reinvestment of dividends.  The historical stock performance shown on the
graph is not necessarily indicative of future stock performance.

Related Transactions

   Mr. Garnier, our President, CEO and Chairman, is a beneficial owner of
approximately 10 percent of the outstanding stock of California Michigan Land
and Water Company (California Michigan).  He is also a director of California
Michigan.  East Pasadena Water Company (East Pasadena), a water purveyor, is a
wholly owned subsidiary of California Michigan. In 2000, East Pasadena
participated in employee insurance coverage with the Company and its wholly-
owned subsidiary, Suburban Water Systems ("Suburban"), and reimbursed Suburban
an aggregate of $28,498, representing its proportionate share of the cost of
employee insurance coverage and other services.

The Company's Noncontributory Defined Benefit Pension Plan owns 17 percent of
the outstanding stock of California Michigan.  As of December 30, 1999, the
Pension Plan was terminated, all benefit accruals were frozen, and all benefit
accruals ceased.  The Company anticipates that the Plan assets will be
distributed, as permitted by the Employee Retirement Income Security Act
(ERISA), in 2001.

  In 2000, Suburban made a lease payment of $55,365 for the use of water rights
owned by a family trust of Mr. Garnier.  The payments made to the family trust
were at the same rate and terms as payments made to non-related parties.

The foregoing transactions were reviewed and approved by the non-employee
Directors of the Company.  Mr. Garnier did not participate in the Board's
consideration of these transactions.

Executive Officers' Change of Control Compensation Agreements

   In 1998, Messrs. Garnier and Moerbeek entered into change of control
compensation agreements with the Company.  The Company has agreed to provide
benefits and payments to Messrs. Garnier and Moerbeek 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.  In 1999, Messrs. Gallarda and Tekulve entered into similar
agreements. Under these agreements, the Company has agreed to provide severance
benefits and payments to Messrs. Gallarda, Quinn and Tekulve based on 1.5 times
their respective average five-year compensation if certain conditions are met.

  For purposes 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 of Directors 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, Gallarda, Quinn and Tekulve will
be triggered if one 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, 2000, assuming termination met the
requirements for a severance payment, are as follows: Mr. Garnier - $1,131,628;
Mr. Moerbeek - $838,686; Mr. Gallarda - $303,908, Mr. Quinn - $287,537; and Mr.
Tekulve $258,500. 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
and Moerbeek and $4,000 each for Messrs. Gallarda, Quinn and Tekulve.

Supplemental Executive Retirement Plan

   The Southwest Water Company Supplemental Executive Retirement Plan (the
"SERP") was adopted by Southwest Water Company effective May 8, 2000.  An
employee must be selected by the Compensation Committee of the Board of
Directors to participate in the SERP.  Two executive officers of the Company and
its participating subsidiaries are participants in the SERP, Messrs. Garnier and
Moerbeek.  Under the SERP, in most cases, a vested participant with 5 to 10
years of service will be eligible for a yearly benefit for his or her lifetime
beginning at age 65 equal to: (1) the participant's average annual compensation
multiplied by (2) the applicable compensation percentage less (3) the Social
Security benefit for the most recent five years of employment and less (4)
benefits received under the Company-sponsored Noncontributory Defined Benefit
Pension Plan (the "Pension Plan").  The Pension Plan was terminated December 30,
1999.

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

         *The calculations above assumed Mr. Garnier had 30 years of service in
         the Pension Plan and Mr. Moerbeek had five years of service in the
         Pension Plan.

     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, 2000, the base compensation for the participating officers
was: Anton C. Garnier - $255,000 and Peter J. Moerbeek - $200,000.  Their years
of credited service were 31 and 6, respectively.  Maurice A. Gallarda, Thomas C.
Tekulve and Michael O. Quinn were not eligible for SERP benefits on December 31,
2000.  The SERP is currently funded through corporate-owned life insurance.

Report of the Compensation Committee of the Board of Directors

Executive Officer Compensation Philosophy

  The compensation philosophy for executive officers is to ensure that
compensation be 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 salaries of the executives, 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 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 meeting certain financial objectives for the
Company and on an executive's achievement of goals in his or her area of
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.

  Financial goals and performance-based measures are established by the
Committee at the beginning of each year.  Awards are made at the end of the year
based on actual performance.  Each year, the Committee establishes a performance
threshold.  No awards are made if the performance threshold is not met.  In
2000, the results for the year exceeded the threshold set by the Committee, and
incentive compensation awards were approved for the Company's executives.

Long-term Incentive Compensation

  The purpose of long-term incentives is to encourage and facilitate long-term
Company performance through greater personal stock ownership by the executive
officers and thus strengthen both their personal commitments to the Company and
a longer-term perspective

                                       15


in their managerial responsibilities. This component of an executive officer's
compensation links the officer's interests with the Company's long-term goals
and with the interests of the Company's stockholders. Currently, the primary
form of long-term incentive compensation is non-qualified stock options. The
Committee approves stock options for all executives and managers.

  In determining the number of stock options awarded, the 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 Committee compares the Company's option grant levels with similar
industry practices.

Chief Executive Officer Compensation

     Anton C. Garnier has been President and 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 2000 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, return on equity and the creation of
stockholder value.  The Committee also evaluated Mr. Garnier's progress in
attaining qualitative objectives in areas such as investor relations, planning
for the Company's long-term future, setting strategic objectives, and
communications. The Committee did not use specific weighting factors with
respect to quantitative and qualitative performance measures.

     In determining Mr. Garnier's performance for 2000, the Committee gave
particular emphasis to the continuing improved operating results of the
Company's contract operations subsidiary.  After the Committee's deliberations,
the Committee increased Mr. Garnier's annual salary to $290,000, effective
January 1, 2001, and awarded him an incentive compensation amount of $175,000
for 2000.  In addition, on February 8, 2001, the Committee awarded Mr. Garnier a
stock option grant of 50,000 shares of the Company's Common stock in recognition
of the Company's five-year performance.

                         ITEM 1 - ELECTION OF DIRECTORS

The Board of Directors

   The Board of Directors is divided into three classes, currently consisting of
two classes of three Directors and one class of one Director whose terms expire
at successive annual meetings.  The three Class III Directors are nominated for
election at our 2001 Annual Meeting for a three-year term expiring at our Annual
Meeting in the year 2004.

officer of the Company. None of the entities by which the Directors are employed
is related to the Company. No Director is a director of any other corporation
subject to Sections 12 or 15(d) of the Securities Exchange Act of 1934 or
registered as an investment company under the Investment Company Act of 1940. No
Director or executive officer of the Company has been, during the last five
years, involved in a legal proceeding of the type that would require disclosure
herein by the Securities Exchange Act of 1934. There are no arrangements or
understandings between any Director and any other persons pursuant to which any
Director was selected as a Director or nominee of the Company or of any other
company.

 Your Board of Directors recommends a vote FOR the election of these nominees.

           ITEM 2 - RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

   The Board of Directors has selected KPMG LLP as the Company's independent
auditors for the year ending December 31, 2001.  KPMG LLP has audited the
Company's financial statements since 1978.

   Representatives of KPMG LLP are expected to be present at the Annual Meeting
and will have the opportunity to make a statement if they so desire and will be
available to respond to appropriate questions.

   The fees billed for professional services for the audit of the Company's
annual financial statements for the year-ended December 31, 2000, and for the
reviews of the financial statements included in the Company's Quarterly Reports
on Form 10-Q for the year 2000 were $150,300.  Included in that amount were fees
related to tax services.

   KPMG LLP did not render professional services relating to financial
information systems design and implementation for the year ended December 31,
2000.

   Stockholder ratification of the selection of KPMG LLP as the Company's
independent auditors is not required by the Company's Bylaws or otherwise.
However, the Board is submitting the selection of KPMG LLP to the stockholders
for ratification as a matter of corporate practice.

  If the stockholders fail to ratify the selection, the Board will reconsider
whether or not to retain that firm.  Even if the selection is ratified, the
Board in its discretion may direct the appointment of a different independent
accounting firm at any time during the year if the Board determines that such a
change would be in the best interests of the Company and its stockholders.

  The favorable vote of a majority of the votes cast is required to ratify the
appointment of KPMG LLP.  Thus, abstentions and broker non-votes on this
proposal will not be counted as votes for or against the proposal.

  Your Board of Directors unanimously recommends a vote FOR Item 2.

                                       19


Report of the Audit Committee of the Board of Directors

     The Audit Committee of the Board of Directors is composed of three
independent directors and operates under a written charter adopted by the Board
of Directors.  Each member of the Audit Committee meets the independence
requirements set by the National Association of Securities Dealers.  A copy of
the Company's Audit Committee Charter is included as Appendix A to this Proxy
Statement.

     Management is responsible for Southwest Water's internal controls,
financial reporting process 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 to issue a report thereon.  The Audit
Committee's responsibility is to monitor and oversee this process.

     In the context stated above, the Audit Committee has met and held
discussions with management and with the independent auditors.  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," and the Audit
Committee discussed with the independent auditors that firm's independence.

     Based upon the Audit Committee's review and discussions referred to above,
the Audit Committee has recommended to the Board of Directors that the audited
financial statements be included in the Company's Annual Report on Form 10-K for
the year ended December 31, 2000 for filing with the Securities and Exchange
Commission.

                            Southwest Water Company
            Charter of the Audit Committee of the Board of Directors


I.  Audit Committee Purpose

    The Audit Committee (the "Committee") is appointed by the Board of Directors
    to assist the Board in fulfilling its oversight responsibilities. The
    Committee's primary duties and responsibilities are to assist the Board with

       auditors.

    .  The Company's compliance with legal and regulatory requirements.

III.  Audit Committee Responsibilities and Duties

      While the Committee has the responsibilities and powers set forth in this
      Charter, it is not the duty of the Committee to plan or conduct audits or
      to determine that the Company's financial statements are complete and
      accurate and are in accordance with generally accepted accounting
      principles. Such duties are the responsibility of management and the
      independent auditors.

      Nor is it the duty of the Committee to conduct investigations, to resolve
      disagreements, if any, between management and the independent auditors or
      to assure compliance with laws and regulations and the Company's Code of
      Conduct.

    is not being adequately addressed by management, it shall be communicated to
    the Committee.

9.  On an annual basis, the Committee shall review and discuss with the
    independent auditors all significant relationships they have with the
    Company that could impair the independence of the independent auditors, and
    ensure that the independent auditors submit annually a formal written
    statement including the written disclosures required by Independence
    Standards Board Standard No. 1, delineating all relationships between the
    independent auditors and the Company.

10. The Committee shall review and approve requests for significant consulting

    in the proxy as required by the Securities and Exchange Commission.
