Document Description
Rainbow Municipal Water District (District) owns and operates the existing Morro Hills, Vallecitos, and Rainbow Hills pump stations. The Morro Hills Pump Station (PS) serves the Morro Tank, the Vallecitos PS serves the Vallecitos Tank, and the Rainbow Hills PS serves the Rainbow Hills Reservoir. During both planned and unplanned power outages, and routine maintenance operations, staff must manually connect power from the portable generators to each pump station’s electrical bus bar.
Especially during emergency conditions like a fire, this type of work is considered high risk. The project involves the installation of a manual transfer switch (MTS) at each pump station to allow any staff member to safely and easily connect to temporary generator power.
