Water Code Sections 10610 through 10656 of the Urban Water Management Planning Act (Act) require
every urban water supplier providing water for municipal purposes to more than 3,000 customers or
supplying more than 3,000 acre-feet (AF) of water annually to prepare, adopt, and file an Urban Water
Management Plan (UWMP) with the California Department of Water Resources (DWR) every five years in
the years ending in zero and five. The 2015 UWMP updates are due to DWR by July 1, 2016.
This UWMP provides DWR with a detailed summary of the present and future water resources and
demands within the City of La Habra’s (City) service area and assesses the City’s water resource needs.
Specifically, the UWMP provides water supply planning for a 25-year planning period in five-year
increments and identifies water supplies needed to meet existing and future demands. The demand
analysis must identify supply reliability under three hydrologic conditions: a normal year, a single-dry year,
and multiple-dry years. The City’s 2015 UWMP updates the 2010 UWMP in compliance with the
requirements of the Act as amended in 2009. See final plan below: Final Urban Water Management Plan
