Water Supply Master Plan
A reliable supply of clean water is necessary for the social, economic, and environmental well-being of Santa Clara County. The Water Supply Master Plan (WSMP) is Valley Water’s guiding document for long-term water supply investments to ensure water supply reliability for the County. Updated about every five years, this long-range plan assesses future county-wide demands and evaluates and recommends water supply and infrastructure projects to meet those demands to achieve Valley Water’s level of service (LOS) goal through the planning horizon. Valley Water’s LOS goal is to “Meet 100 percent of annual water demand during non-drought years and at least 80 percent demand in drought years.”
The most recent plan, Water Supply Master Plan 2040, was adopted by the Valley Water Board of Directors (Board) in 2019. Valley Water has started a two-year process to develop the Water Supply Master Plan 2050, which extends the planning horizon to 2050.
On Sept. 19, 2023, Valley Water held a special workshop to provide board members and the public with an update on the development of the Water Supply Master Plan 2050. The board packet and recording can be found here.
On Jan. 9, 2024, the Board of Directors received the second update from Valley Water staff on the development of the Water Supply Master Plan 2050. The board packet and recording can be found here.
