Sheila Tank Replacement Project

Sheila Tank Replacement Project

The North Coast County Water District (NCCWD or District) proposes to replace a water tank (Sheila Tank) located off of Sheila Lane in the City of Pacifica (referred to here as the "proposed project"). The existing Sheila Tank is 32-foot diameter, 21-foot tall redwood tank with a capacity to hold 0.1 million gallons (MG); the District Typically operates the tank at a maximum water level of 14.5 Feet. The Existing Tank is leaking, not anchored, and vulnerable to seismic events. The proposed project would replace the existing deteriorating tank to meet current standards of public health and safety, and would increase the size of the tank to address a storage deficit and a need for improved fire suppression in the area served by the tank. As recommended in NCCWD's 20-year Water Master Plan, the proposed project would increase the size of the tank to 0.2 MG. The new tank would be a 40-45 foot diameter and 21-25 foot tall welded steel tank surrounded by a chain link fence with barbed wire and re-connected to the existing regulator station. Discharge water flow rates would remain the same regardless of the increased tank size. The proposed project would not increase the capacity of the water system, as the pipeline connecting to the tank would not be increased. The proposed project would merely increase the storage area to help meet existing daily demand as well as increase water storage for fire suppression. Sheila Tank currently services an area of approximately 265 acres that include approximately 1,210 service connections, and also assists an additional zone which contains and additional 760 service connections. The service area and number of residences served would remain unchanged under the proposed project.
