Sewage

On 13th May, 2008, the Omaha city council approved a USD510,000 contract with Parsons Brinckerhoff to carry out geotechnical and geophysical exploration and testing of soil and rock samples for the planned deep tunnel to be constructed under Omaha for storage and conveyance of combined storm water and sanitary sewage. The tunnel will be about 53.4 m deep and will take in overflow waste water and funnel it to a new treatment facility south of downtown. PB will use boring machines to dig six test holes along the 9.6 km-long, north-to-south route between the Gallup campus and the Veterans Memorial bridge. The machines will dig each hole to a depth of 90 metres and then bring up soil and rock samples to see what the nature of the limestone is deep underground. Drilling is expected to begin in early June and should be finished in a couple of months. The tunnel is expected to cost between USD300 million and USD400 million, making it the single most expensive component of the sewer overhaul.

Los Angeles

Parsons and Jacobs Associates has been selected by the Sanitation Districts of Los Angeles County to prepare a feasibility study and perform preliminary engineering for a new tunnel and ocean outfall, where chemically treated wastewater would be discharged into the ocean. The tunnel would start at a water pollution control plant in Carson with an onshore shaft and tunnel and run about 9.65 km until it goes offshore. Offshore it will involve either a tunnel, combination conventional outfall and tunnel or a conventional outfall. The new tunnel and outfall, which would be one of the world's largest and would provide improved reliability and operational capability, would be about 6 m in diameter, and it could be 25.7 to 27.4 km long by the time it is all done. The existing tunnels go about 3.2 km offshore to a depth of 60 m. Those tunnels, 2.4 m and 3.6 m in diameter respectively, are more than 50 years old, and during severe storms they run at full capacity.The districts are evaluating the feasibility of a new tunnel and ocean outfall in the context of a comprehensive master facilities plan to cover its joint outfall system, which serves a large portion of metropolitan Los Angeles County. During the feasibility phase, a team of Parsons and Districts engineers will evaluate several onshore and offshore alignments and potential diffuser locations. Following selection of the preferred alternative, Parsons will perform the preliminary design. Visit www.parsons.com, www.jacobssf.com and www.lacsd.org 36/06.

The Sanitation Districts of Los Angeles County (Sanitation Districts) awarded a EUR533,48 million (USD630 million) construction contract for the Clearwater Project to Dragados USA Inc, belonging to ACS Group. The project will protect local waterways by addressing aging infrastructure and involves building a new 11.27 km (7‐mile) long, 5.49 m (18‐foot) diameter tunnel to convey treated water from the Joint Water Pollution Control Plant in Carson to existing ocean outfalls at Royal Palms Beach in San Pedro. Construction will begin this year and is scheduled to end in 2026. Visit https://www.grupoacs.com/. 43/18.
