Urban Water Management Plans (UWMP) are prepared by California's urban water suppliers to support their long-term resource planning and ensure adequate water supplies are available to meet existing and future water demands. Every urban water supplier that either provides over 3,000 acre-feet of water annually or serves more than 3,000 or more connections is required to assess the reliability of its water sources over a 20-year planning horizon considering normal, dry, and multiple dry years. San Juan has adopted and submitted to the Department of Water Resources its 2020 UWMP, which is available below.  Contact Greg Zlotnick @ gzlotnick@sjwd.org or 916-791-6933 for further information.
