Newtown Creek Water Pollution Control Plant

Rank #4 (Tied)
Cost: $493 million

A joint venture of Slattery Skanska, Picone/McCullagh JV and Perini Corp. began work in August to upgrade New York City's largest wastewater treatment facility.

Work on the Newtown Creek Water Pollution Control Plant in the Greenpoint section of Brooklyn, includes expanding the plant from 16 treatment areas to 24.

The job will involve extensive new construction of piping, aeration and sedimentation tanks and a new control building, as well as upgrading of existing plant components. In addition, the new and existing sections must be integrated.

Skanska USA Civil companies Slattery Skanska and Gottlieb Skanska and Underpinning & Foundation Skanska will do 45 percent of the work, Picone/McCullagh JV will do 30 percent and Perini Corp. will do 25 percent.

This contract is one of many that have been awarded as part of a massive effort to upgrade Newtown Creek to bring it into compliance with secondary treatment requirements mandated by the federal Clean Water Act. The law was enacted to maintain the quality of the nation's water supplies and eliminate the discharge of harmful materials into water.

The New York City Department of Environmental Protection has until December 2007 to provide secondary treatment of all sewage at the facility. When completed, the 53-acre facility will be the last of the city's 14 treatment plants to be upgraded to meet federal standards.

The work includes demolishing and reconstructing four aeration tanks and four sedimentation tanks at the Central Battery area of the plant. Modifications to eight aeration and eight sedimentation tanks in the South Battery area will also be undertaken. The contract requires construction of new foundations and piers for support of air main as well as odor-control piping at both locations.

Work on the new North Battery tanks includes construction of new grit and aeration tanks and sedimentation tanks. An influent feed system will also be installed, which includes 96-ft. of encased piping. The new North Battery tanks will measure approximately 310,000 sq. ft. and require more than 85,000 cu. yds. of concrete for construction. A new 40,000-sq.-ft. control building will be constructed to service the new and modified tanks.

Mechanical work includes installation and procurement of eight new process air blowers in the existing main building and utility work throughout the construction area.
