Bay Park Sewage

Bay Park Sewage Treatment Plant

The Bay Park Sewage Treatment Plant was originally constructed in the late 1940s, and was placed into operation in 1950. The sewage service area tributary to the Bay Park STP is approximately 70 square miles in the western portion of the County with an estimated population of approximately 550,000.  The majority of the sanitary flow is from residential housing with the remainder from commercial establishments. 

Hurricane Sandy’s high winds, severe flooding, and power outages caused widespread damage to the Bay Park STP. As a result of Hurricane Sandy approximately 50 structures, numerous mechanical and electrical systems, and operating equipment were damaged at the STP.

The plant lost total conveyance and treatment services for three days. This Plant failure resulted in an estimated 100 million gallons of untreated sewage overflowing into the streets, adjoining neighborhoods and Hewlett Bay. In addition, another 2.2 million gallons of partially treated effluent was released into the bay.

Although emergency work was immediately undertaken to return the plant to service as quickly as possible many of the plant’s facilities required extensive long-term repairs.

A More Resilient Future

FEMA has provided an additional $810 million in funding, through a Section 428 Capped Grant, for repair and mitigation measures. The Section 428 Capped Grant incudes $427 million for repair/restoration and contents from Hurricane Sandy damages across the medical campus and $383 million in Section 406 hazard mitigation costs.

The represents architectural, mechanical, and electrical repairs across the Bay Park campus, including the electrical distribution system, satellite pump stations, effluent facilities, settling tanks, fire protection building, and utility tunnel.  As a critical service provider for the inhabitants of a large portion of Nassau County, the project was given priority as one of the first included in the PAAP 428 program.

The project’s mitigation plan is intended to protect all systems and equipment within the plant such that, in the event of a 500 year flood, the plant can continue to operate with minor or no disruption to services. Primary mitigation measures include constructing a flood boundary protection system around the entire plant, protecting critical systems and equipment within the plant by elevating equipment, providing updated and submersible equipment, and dry flood-proofing enclosures.
