Water Conservation & Shortage Stages

SMWD WSCP Final May 2021 Opens in new window

In May of 2021, the District updated its Water Conservation Ordinance and Water Shortage Contingency Plan. The Water Shortage Contingency Plan provides guidance on what water supply shortage actions the District may implement in the event of a water shortage condition. 

The District's Ordinance 2021-05-05 establishes Permanent Water Conservation Best Management Practices (BMPs) that are in effect at all times in the District's service area. These BMPs are intended to promote water conservation as a permanent way of life and prevent the waste of water, even during years of normal or above normal rainfall and water supply. 

Summarized above are the year-round Water Conservation BMPs as well as the water shortage actions for any given declared water shortage stage. The specific text can be found in the documents on the top right of this page.
