The Department of Public Works will construct a new 54-inch diameter force main sewer line. The new force main will operate as a parallel system in conjunction with the existing 48-inch force main. The new force main is needed to avert a potential sewage spill that could occur from an overflow or failure of the existing 54-year-old force main.

The project objectives are to increase sewage capacity, create pipeline redundancy and allow for maintenance of the system.

The performance of the existing force main is of concern because:

• The existing force main has been in continued service for over 50 years without any maintenance. To avoid a potential failure, redundancy is needed to allow for assessment of its condition and maintenance.
• During severe wet weather, peak flows to the Venice Pumping Plant (VPP) have exceeded the capacity of the only existing force main conveying wastewater from the VPP to the Hyperion Water Reclamation Plant (HWRP). Without additional capacity, there is a risk of an overflow of sewage into city streets and surface waters.

With the systems working together, sewage flow from the Venice Pumping Plant can be conveyed to the Hyperion Water Reclamation Plant in Playa del Rey using either or both force mains. The project will also replace backup generators of the Venice Pumping Plant.

The new force main will originate at the Venice Pumping Plant (VPP) at 140 Hurricane Street and cross Grand Canal, travel east to Marquesas Way, then south along Via Marina crossing the Marina Del Rey and Ballona Creek Channels to meet an existing coastal interceptor sewer junction structure on Vista Del Mar near Waterview Street via Pacific Avenue.
