NYCDEP Newtown Creek Wastewater Treatment Plant Preliminary Treatment Upgrade

The largest of New York City’s wastewater treatment plants, the Newtown Creek Wastewater Treatment Plant underwent a $5 billion upgrade to improve effluent quality and increase wet weather treatment capacity from 620 million gallons per day (mgd) to 700 mgd.

Hazen, as part of a Joint Venture, provided the City with program management, facility planning, design services, and operations assistance.

  • Upgraded process has consistently exceeded permit requirements for 90% removal of Carbonaceous Biological Oxygen and Suspended Solids.
  • Extensive field sampling was performed to characterize influent wastewater characteristics and develop a calibrated BioWin model to optimize performance.
  • Process control automation reduced operational costs.
