Water Management Plans
Integrated Regional Water Management Plan
The Antelope Valley Integrated Regional Water Management Plan (IRWMP), also known as The AV Water Plan, is a multi-county collaboration effort developed to address regional concerns about water supply reliability, water quality, flood protection, environmental resources and land use management in the Antelope Valley.
Antelope Valley Integrated Regional Water Management Plan (IRWMP)
Urban Water Management Plan
In 1983, the California Legislature enacted the Urban Water Management Planning Act (AB 797; Water Code, Division 6, Part 2.6, Section 10610-10656). This Act requires water suppliers serving more than 3,000 customers or providing more than 3,000 acre-feet of water annually to prepare an Urban Water Management Plan (UWMP) to promote water demand management and efficient water use. The UWMP is designed to provide an effective management and planning tool for water agencies throughout California. It allows for a succinct summary of an agency’s water supplies, demands and plans to ensure future reliability. It also encourages the efficient management of water supplies by requiring a discussion of potential water transfers and exchanges, desalination and recycled water opportunities. The UWMP shall be updated at least once every five years, in calendar years ending in 5 and zero.
