          SJW Corp. (the "Registrant") hereby incorporates by reference into

Securities and Exchange Commission (the "Commission"): 

         (a)  The Registrant's Annual Report on Form 10-K for the fiscal year 
ended December 31, 2004, filed with the Commission on March 7, 2005, as 
amended on Form 10-K/A on March 25, 2005;

         (b)  The Registrants Quarterly Reports on Form 10-Q for the fiscal 
quarters ended March 31, 2005, and June 30, 2005, filed with the Commission 
on May 6, 2005 and August 5, 2005;

         (c)   The Registrant's Current Report on Form 8-K filed with the 
Commission on August 2, 2005 (Item 1.01 only); and

         (d)  The description of the Registrant's Common Stock contained in a 
registration statement filed under the Securities and Exchange Act of 1934, as 
amended (the "1934 Act"), including any amendment or report filed for the 
purpose of updating such description.

          All reports and definitive proxy or information statements filed 
pursuant to Section 13(a), 13(c), 14 or 15(d) of the 1934 Act after the date 
of this Registration Statement and prior to the filing of a post-effective 
amendment which indicates that all securities offered hereby have been sold 
or which de-registers all securities then remaining unsold shall be deemed to 
be incorporated by reference into this Registration Statement and to be a 
part hereof from the date of filing of such documents.  Unless expressly 
incorporated into this Registration Statement, a report furnished but not 
filed on Form 8-K shall not be incorporated by reference into this 
Registration Statement.  Any statement contained in a document incorporated 
or deemed to be incorporated by reference herein shall be deemed to be

extent that a statement contained herein or in any subsequently filed 
document which also is deemed to be incorporated by reference herein modifies 
or supersedes such statement.  Any such statement so modified or superseded 
shall not be deemed, except as so modified or superseded, to constitute a 
part of this Registration Statement.

Item 4.  Description of Securities
         -------------------------
         Not applicable.

Item 5.  Interests of Named Experts and Counsel
         --------------------------------------
         Not Applicable.

Item 6.  Indemnification of Directors and Officers
         -----------------------------------------

          Section 317 of the California Corporations Code authorizes a court

directors and officers in terms sufficiently broad to permit such 
indemnification under certain circumstances for liabilities (including 
reimbursement for expenses incurred) arising under the Securities Act of 
1933, as amended (the "1933 Act").  The Registrant's Bylaws provide for 
permissible indemnification of officers, employees and other agents to the 
maximum extent permitted by the California Corporations Code.  In addition, 
the Registrant has entered into Indemnification Agreements with each of its 
directors which provide its directors with further indemnification to the 
maximum extent permitted by the California Corporations Code.

Item 9.  Undertakings
         ------------


          A.  The undersigned Registrant hereby undertakes: (1) to file, 
during any period in which offers or sales are being made, a post-effective 
amendment to this Registration Statement: (i) to include any prospectus 
required by Section 10(a)(3) of the 1933 Act, (ii) to reflect in the 
prospectus any facts or events arising after the effective date of this 
Registration Statement (or the most recent post-effective amendment thereof) 
which, individually or in the aggregate, represent a fundamental change in 
the information set forth in this Registration Statement and (iii) to include 
any material information with respect to the plan of distribution not 
previously disclosed in this Registration Statement or any material change to 
such information in this Registration Statement; provided, however, that 
clauses (1)(i) and (1)(ii) shall not apply if the information required to be 
included in a post-effective amendment by those clauses is contained in 
periodic reports filed with or furnished to the Commission by the Registrant 
pursuant to Section 13 or Section 15(d) of the 1934 Act that are incorporated 
by reference into this Registration Statement; (2) that for the purpose of 
determining any liability under the 1933 Act, each such post-effective 
amendment shall be deemed to be a new registration statement relating to the 
securities offered therein and the offering of such securities at that time 
shall be deemed to be the initial bona fide offering thereof; and (3) to 
remove from registration by means of a post-effective amendment any of the 
securities being registered which remain unsold at the termination of the 
Registrant's Employee Stock Purchase Plan.  

          B.  The undersigned Registrant hereby undertakes that, for purposes 
of determining any liability under the 1933 Act, each filing of the 
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the 
1934 Act that is incorporated by reference into this Registration Statement 
shall be deemed to be a new registration statement relating to the securities 
offered therein, and the offering of such securities at that time shall be 
deemed to be the initial bona fide offering thereof.

          C.  Insofar as indemnification for liabilities arising under the 
1933 Act may be permitted to directors, officers or controlling persons of 
the Registrant pursuant to the indemnification provisions summarized in Item 
6 or otherwise, the Registrant has been advised that, in the opinion of the 
Commission, such indemnification is against public policy as expressed in the 
1933 Act and is, therefore, unenforceable.  In the event that a claim for 
indemnification against such liabilities (other than the payment by the 
Registrant of expenses incurred or paid by a director, officer, or 
controlling person of the Registrant in the successful defense of any action, 
suit or proceeding) is asserted by such director, officer or controlling 
person in connection with the securities being registered, the Registrant 
will, unless in the opinion of its counsel the matter has been settled by 
controlling precedent, submit to a court of appropriate jurisdiction the 
question whether such indemnification by it is against public policy as 
expressed in the 1933 Act and will be governed by the final adjudication of 
such issue.



                                SIGNATURES


          Pursuant to the requirements of the Securities Act of 1933, as 
amended, the Registrant certifies that it has reasonable grounds to believe 
that it meets all of the requirements for filing on Form S-8, and has duly 
caused this Registration Statement to be signed on its behalf by the 
undersigned, thereunto duly authorized, in the City of San Jose, State of 
California on this 8th day of August, 2005.
