2020 Water Shortage Contingency Plan and Urban Water Management Plan Update

Atascadero Mutual Water Company (AMWC) is currently in the process of preparing a Water Shortage Contingency Plan (WSCP) and updating its Urban Water Management Plan (UWMP) as required by the California Department of Water Resources.


The WSCP and UWMP update are prepared by urban water suppliers to support their long-term resource planning and ensure adequate water supplies are available to meet existing and future water demands over a 20-year planning horizon. The plans include an analysis of projected population growth, current and future water demands, as well as water supply and pumping data.
