Securing Federal Funding for Sustainable Wastewater Treatment: Bay Park STP Recovery

Client: Nassau County
Location: Nassau County, NY

The Bay Park STP Hurricane Sandy Recovery Program, a partnership between Hazen and Sawyer and ARCADIS, was created to assist Nassau County in the long-term Hurricane Sandy recovery effort for the facility. To date, over $800 million has been secured through FEMA and outside funding to be used to rehabilitate damaged treatment unit processes and to protect critical infrastructure from future flood events.

Hazen and Sawyer led the immediate recovery effort at the Bay Park STP following the facility shutdown during flooding from Hurricane Sandy. Through the efforts of on-site engineers working in conjunction with Nassau County Department of Public Works the facility was returned to operation in less than 72 hours.

Flood wall/berm is being constructed to ensure critical infrastructure is safe from future extreme flood events.

The new process aeration building will feature sustainable green design of critical process infrastructure and be protected against future flooding.

The DEMON process pilot conducted at the facility achieved and maintained high levels of nitrogen removal throughout testing, and can enable utilities to save over $1 million a year in chemical costs.

Project Outcomes and Benefits

  • Master planning at the facility focused on sustainable facility operation, including the design of a new energy efficient process aeration system, the beneficial reuse of biogas from anaerobic digestion, and the use of a deammonification process to improve overall plant performance during future biological nitrogen removal operations.
  • Creation of a sea wall/land berm at the facility's perimeter to protect it against future storm surges from the nearby bay.
  • Multiple construction contracts implemented concurrently on an aggressive schedule to ensure the facility is protected as quickly as possible.
  • Every major milestone of the recovery effort has been met while meeting current wastewater treatment goals.
  • Assistance to Nassau County in securing federal funding for the rehabilitation and flood protection of the Bay Park STP.
  • Finished facility will be a sustainable wastewater treatment system, one that is both energy efficient and protected from future flooding.
