increased use (10633(g)).
#30. (Describe) all water supply projects and water supply programs that may be
undertaken by the urban water supplier to meet the total projected water use as
established pursuant to subdivision (a) of Section 10635. The urban water supplier shall
include a detailed description of expected future projects and programs, other than the
demand management programs identified pursuant to paragraph (1) of subdivision (f),
that the urban water supplier may implement to increase the amount of the water
supply available to the urban water supplier in average, single-dry, and multiple-dry
water years. The description shall identify specific projects and include a description of
the increase in water supply that is expected to be available from each project. The
description shall include an estimate with regard to the implementation timeline for

Proposed PVWMA Water Supply Projects
$ Water Conservation - Implementation of the Water Conservation 2000 plan will provide up to
approximately 5,000 acre-feet per year per year of reduced water demand through agricultural
and domestic water conservation programs.
$ Local Water Supplies - In addition to development of the Harkins Slough, Murphy Crossing, and
College Lake projects, a project to utilize recycled water from the City of Watsonville
Wastewater Treatment Plant has been developed. The flow through the Watsonville Plant that
can be effectively utilized is approximately 4,000 acre-feet per year.
The 2005 estimated cost of this series of projects is summarized in Table 4.9.
