Plant 5’s New Year-Round Treatment Facility on Haypath Road to Bolster PWD’s Capacity and Emerging Contaminant Treatment

The Plainview Water District (PWD) has begun construction on a major water treatment project at its Plant 5 facility on Haypath Road. Plant 5 is the District’s largest water production site, housing four wells capable of producing up to eight million gallons of water per day. The upcoming improvements focus on treating 1,4-dioxane and perfluorinated compounds and will transform this site into a fully operational, year-round treatment facility.

“We are incredibly proud of the progress being made at Plant 5, as this project represents the single most significant investment in the future reliability and quality of our drinking water,” said PWD Commissioner Marc Laykind. “This facility is the pillar of our operations and ensuring it is equipped with advanced treatment technology is essential to meeting the long-term needs of the POB community.”

To support the District’s capacity needs during the high-demand summer months, PWD has been operating an interim treatment facility at Plant 5 consisting of both the Advanced Oxidation Process (AOP) and Granular Activated Carbon (GAC). This temporary system enabled one of the wells to remain in service while full-scale design and health department review progressed. PWD secured approvals from both the New York State and Nassau County Health Departments, advanced the project through the public bidding process and, following the award of the contract, began construction on the permanent facility. Once complete, this plant site will have AOP, GAC and packed-tower aeration treatment on all four of its supply wells.

“Our team’s focus on long-lasting infrastructure improvements ensures that Plant 5 will continue to serve the community for decades to come,” said PWD Commissioner Andrew Bader. “This project is another example of our commitment to planning ahead and making the necessary investments to support water reliability throughout Plainview and Old Bethpage.”

In August 2020, the New York State Health Department finalized regulations establishing maximum contaminant levels (MCLs) for 1,4-dioxane, PFOA, and PFOS. New York became the first state in the nation with an enforceable MCL for 1,4-dioxane. To stay ahead of the compliance curve, the District launched an aggressive capital improvement plan that included major investments at Plant 5 and other facility locations to meet the new regulatory standards.

“This facility plays an essential role in our ability to meet the community’s daily water needs, and these upgrades will solidify its place within our long-term treatment strategy,” said PWD Commissioner Michael Chad. “Our engineers and staff have worked diligently to move this project forward, and we look forward to bringing the permanent facility online once construction is complete.”

The Plainview Water District is recognized regionally for its leadership in emerging contaminant treatment. The District has also been very successful at securing more than $34 million in grant funding for emerging contaminant treatment construction, including $13.8 million to specifically support Plant 5’s upgrades.
