Newtown Creek Wastewater Treatment Plant Upgrades


 


The Newtown Creek Wastewater Treatment Plant has been in operation since 1967 and is the largest of New York City’s wastewater treatment plants. Plant upgrades will increase treatment capacity to 310 mgd, approximately 18% of the city’s total wastewater. HAKS provided resident engineering inspection services as a major subconsultant to the tri-venture providing construction management services to the NYCDEP for this $1.16 billion upgrade. Capital improvement projects include:

  • Central Residuals Building. This $370 million construction project provided a centralized location for the handling and disposal of residuals from the treatment process.
  • South Battery Reconstruction and South Control Building. This $727 million project provided a full upgrade of the South Battery and construction of a new South Control Building. The South Battery consists of four grit tanks, four aeration tanks and four sedimentation tanks. The new South Control Building houses the return-activated sludge and waste-activated sludge pumping station and the odor control equipment.
  • Sludge Loading Dock. This $45 million project involves demolition of the sludge storage tank. Completion enables development of affordable housing and public space at this spectacular location on the East River in North Williamsburg. Work included a berthing area with marine fender system to serve new sludge transfer vessels, sludge force main, and maintenance dredging in Newtown Creek and Whale Creek. Additional work included inspection of all eight digesters and two sludge storage tanks.
  • Process Wrap-Up. This $19 million project involved miscellaneous improvements throughout the facility to enhance worker safety and increase reliability of the sewage treatment equipment.
