Item 12. Certain Relationships and Related Transactions.


The Company sells water it acquires under a water lease to the Centennial
Water & Sanitation District.  John D. Hendrick, who became a Director of the
Company in November 2000, is the General Manager of the Centennial Water &
Sanitation District.  The Centennial Water & Sanitation District makes
payments to an escrow agent who distributes the funds primarily to the lessor
and the remainder to the Company.  During 2006, 2005 and 2004, the Company
invoiced the Centennial Water & Sanitation District $320,750, $344,894 and
$331,149, respectively, under this arrangement.

     In March 2004, the Company sold a town home to Steven H. Davis, Chief
Executive Officer, President and Director for $160,949, which was comparable
to the price received for similar units from outside customers.  The sales
price approximated the cost of the unit.  In addition, the Company agreed to
lease the unit on a month-to-month basis from Mr. Davis for $1,050 per month
to serve as the model unit for the outside marketing firm.  The Company
terminated the lease in March 2005.

     All of these transactions were approved by the Board of Directors and
were made on terms as fair and reasonable to the Company as those that could
be obtained from non affiliated third parties.  Any future transactions
between the Company and its officers, directors, employees and affiliates
that are outside the scope of the Company's employment relationship with such
persons will be subject to the approval of a majority of the disinterested
members of the Board of Directors based upon a determination that the terms
are at least as favorable to the Company as those that could be obtained from
unrelated parties.

                     Audit Committee Pre-approval Policy

     The Company's independent registered public accounting firm may not be
engaged to provide non-audit services that are prohibited by law or
regulation to be provided by it, nor may the Company's independent registered
public accounting firm be engaged to provide any other non-audit service
unless it is determined that the engagement of the independent registered
public accounting firm  provides a business benefit resulting from its
inherent knowledge of the Company while not impairing its independence.  The
Audit Committee must pre-approve the engagement of the Company's independent
registered public accounting firm to provide permissible non-audit services.
All non-audit services provided by the independent registered public
accounting firm in 2005 and 2006 were pre-approved by the Audit Committee.
