Robertson/Wallan/Hurlbutt Tanks Replacement Project

Robertson/Wallan/Hurlbutt Tanks Replacement Project

Replace the existing 180,000-gallon, in-ground, concrete, finished water storage tank (Hurlbutt Tank) with a new in- ground, 550,000-gallon, pre-stressed concrete tank (Main Tank) located on an adjacent parcel. Replace the existing 20,000-gallon, failing, redwood drinking water storage tank (Wallan Tank) with an approximately 77,000-gallon bolted steel tank. Remove the failing Robertson Tank from the system. Demolish the existing Upper Maple Lane Pump Station and replace it with a new one at the site of the new Main Tank. Demolish the existing Arthur Pump Station and replace it with a new Alderpoint Pump Station. Upgrade the existing Wallan Pump Station to meet the operational requirements of the new Wallan Tank. Install new segments of distribution piping to connect the new tanks and pump stations to the existing distribution system. Install new, diesel-powered, backup generators at the Tobin Well, Upper Maple Lane Pump Station, Alderpoint Pump Station, and Wallan Pump Station. Install new instrumentation, controls, and radio telemetry improvements.
