The purpose of the inter-tie project, which is nearly complete, is to provide a connection between the SFPUC and the East Bay Municipal Utility District (EBMUD). The connection uses existing water system piping in the City of Hayward with connections to EBMUD and SFPUC systems on each end. The connection allows up to 30 mgd of water to flow between the two water systems in the event of critical shutdowns for emergency repairs or maintenance and construction activities. This project is provided in response to the Delivery Reliability level of service goal.

Description
The project primarily consists of:

• New 36-inch-diameter piping and valving at the Newark Turnout to provide an additional connection between BDPL Nos. 1 and 2 to the existing City of Hayward system.
• Six new valves for isolation while maintaining the existing City of Hayward system for conveyance.
• 1.3 miles of new 36-inch-diameter pipe to connect the City of Hayward system to EBMUD and new pump station along this alignment.
