Greenlawn Water District

What Greenlawn Water District does

Greenlawn Water District is a New York State special district and local government entity that supplies potable water to the Greenlawn community in Suffolk County, Long Island, New York. Established in 1927 and operating 24/7/365, the district extracts groundwater through 14 active wells from the Long Island aquifer system, treats and distributes it to residential households and commercial consumers within its exclusive service territory, and maintains storage reserves for fire protection. Technical infrastructure includes Orion Fixed Network radio frequency endpoints for automated meter reading, a GIS-based service line mapping and self-inspection certification system supporting EPA Lead and Copper Rule compliance, and a pilot 1,4-dioxane remediation program using titanium dioxide and hydrogen peroxide oxidants developed in partnership with the NY State Center for Clean Water at Stony Brook University.

The district generates revenue through usage-based water rates charged on a quarterly billing cadence, with rate schedules established annually by an elected three-member Board of Commissioners pursuant to Section 215 of New York State Town Law (e.g., effective January 1, 2026). Operations are funded by ratepayer revenue, supplemented by grants from programs such as the Water Infrastructure Improvement Act (WIIA), which can cover up to $3 million or 60% of qualifying project costs. The district is led by a Chief Plant Operator and governed by Commissioners John H. Clark, James M. Logan, and John McLaughlin, with staggered three-year elected terms. Customer-facing communications run through the district website (greenlawnwater.org), quarterly newsletters, annual Consumer Confidence Reports, public notices, and the Rave Alert emergency notification platform.

Recent regulatory activity includes a 2021 MCL Deferral from NYSDOH for the 1 part per billion 1,4-dioxane standard and ongoing litigation against Dow Chemical, Ferro Corporation, and Vulcan Materials Company to recover remediation costs. The district has been recognized 13 times since 1989 as winner of Suffolk County's Best Tasting Water competition, including back-to-back wins in 2025 and 2026, and has won Best Tasting Water in New York State twice.
