Document Description
The project includes the replacement of approximately 9,000 linear feet of existing water mains along Elena Road, Taaffe Road, Vista Del Valle Court, Old Snakey Road, and Moody Road, in the town of Los Altos Hills. The majority of the proposed mains to be replaced are located within existing road right-of-way. A short segment is proposed as a "cross-country" route across open land owned by the District to connect to the Elena Pump Station. The purpose of the project is to allow improved water flow from the Elena Pump Station to the Altamont tanks and will allow for overall system reliability in the event of an earthquake. Portions of the water main segments to be replaced are made of asbestos concrete, which is brittle and subject to severe damage during seismic events. Other segments consisting of cast iron pipe will also be updated to ductile iron pipe for increased reliability.
