Project Info

Title

Haynes Generating Station Sewer Force Main Project

Description

The Project includes the construction of a new 12-inch diameter sewer force main that would extend from Los Angeles Department of Water Power (LADWP) Haynes Generating Station (HGS) to an existing Los Angeles County Services District (LACSD) 42-inch sewer main located at the LACSD’s Long Beach Water Reclamation Facility. The Project would facilitate the beneficial reuse of up to 2.766 million gallons per day (MGD) of industrial wastewater discharge and 0.075 MGD of on-site storm water runoff (for a total of 2.841 MGD) from the HGS to LACSD’s Long Beach Water Reclamation Facility. Total pipeline installed would be 17,000 feet using a combination of trenching and trenchless construction methods. A flow control/pressure reducing station consisting of an above grade or partially buried structure not to exceed 300 square feet would be constructed at or adjacent to the Long Beach Water Reclamation Facility. In addition, the HGS is currently located outside the LACSD’s adopted sphere of influence. Therefore, as part of the Project, the LACSD proposes to expand its service area boundary to include the HGS and annex the HGS property into the LACSD Sanitary District Number 19. This action would not entail any changes to existing City zoning.
