Venice Dual Force Main

This project consisted of a new 54-inch diameter force main sewer extending 10,392 feet in length, originating from a newly constructed manifold. From the manifold the alignment made its way beneath the Marina Del Rey Harbor inlet and Ballona Creek channel, continuing south under Pacific Avenue and Vista Del Mar to its terminus. The majority of the new 54-inch diameter line was constructed via microtunneling, predominately direct-jacked reinforced concrete cylinder pipe (RCCP) but also included 2,800 feet of 80-inch diameter Permalok Steel Casing with RCCP carrier and 1,800 feet of 88-inch diameter reinforced concrete pipe (RCP) with a 54-inch diameter fiberglass reinforced pipe (FRP) carrier. One of the tunnel drives included two horizontal curves and one vertical curve climbing 50 feet. The project also consisted of the demolition of existing equipment, procurement, and installation of three new generators along with ancillary controllers, transfer switches, and exhaust and cooling systems at a pumping plant. The generators that were furnished and installed included two 750 kilowatts (kW) and one new 1,500 kW complete with emissions control systems and fluid storage.

WRF Lift Station
This project consisted of a single microtunnel drive of 310-feet 60-inch diameter x 0.75-inch wall thickness Trinity Press Fit Steel Casing.

WRF Lift Station

This project consisted of a single microtunnel drive of 310-feet 60-inch diameter x 0.75-inch wall thickness Trinity Press Fit Steel Casing through a composition of poorly graded clean sand, clayey sand, and lean clay, including non-cohesive flowing sands. The microtunnel was installed under a roundabout intersection of Morro Bay Blvd and Quintana Rd. with shafts approximately 20 feet deep, at 12 feet below the groundwater table, and with numerous overlying critical utilities, critical surface improvements, and heavy traffic through the roundabout.
