The Urban Water Management Planning Act requires water suppliers in California, providing water for
municipal purposes either directly or indirectly to more than 3,000 customers or supplying more than
3,000 acre-feet (ac-ft) of water annually, to prepare and adopt an Urban Water Management Plan every
five years which defines their current and future water use, sources of supply and its reliability,
and existing conservation measures.
In recognition of the state requirements, the City of Modesto (City) and the Modesto Irrigation District
(MID) have prepared this joint Urban Water Management Plan (UWMP) for 2010. The purpose of the joint plan
is to provide a planning tool for both agencies in developing, managing and delivering municipal water
supplies to the joint water service area.
