Long-Range Planning
Urban Water Management Planning
How Myoma Dunes Mutual Water Company plans ahead for long-term water reliability — today and for the next 20+ years.
01 — Urban Water Management Planning Act
Urban Water Management Planning Act
California's Urban Water Management Planning Act (UWMP Act), enacted in 1983 under Assembly Bill 797, requires water suppliers to plan ahead for long-term water reliability. Under the Act, any supplier serving more than 3,000 connections — or delivering more than 3,000 acre-feet of water annually — must prepare and submit an Urban Water Management Plan (UWMP) to the California Department of Water Resources (DWR) once every five years.
02 — What's in a UWMP
What's in a UWMP
A UWMP gives water suppliers, regulators, and the public a clear picture of how a system plans to meet demand over the next 20+ years. Each plan includes:
- Projected water demand and supply availability
- A reliability assessment covering normal, single-dry, and multiple-dry year conditions
- Water use efficiency and conservation programs already in place
- A Water Shortage Contingency Plan outlining actions to take during supply shortages
- Progress toward state per-capita water use reduction targets
- Current and planned use of recycled water
