Roslyn WD

The Roslyn Water District has been committed to providing safe, reliable water to its service area since 1910. As one of Long Island's oldest public water suppliers, we maintain transparency through detailed water quality reporting.

Our water system serves approximately 17,900 residents through 5,780 service connections across a 5.1 square mile territory. We draw water exclusively from groundwater sources via seven individual wells and one well field containing eight wells. These wells range in depth from 260 to 530 feet, primarily accessing the Magothy aquifer.

All water undergoes rigorous treatment processes before distribution, including pH adjustment with sodium hydroxide to prevent corrosion and disinfection with calcium hypochlorite. Select wells receive additional treatment through packed tower aeration and granular activated carbon filtration to remove specific organic contaminants.

Our distribution system includes three storage tanks with a combined capacity of 6 million gallons. Water quality is continuously monitored with hundreds of tests annually for over 100 potential contaminants, ensuring compliance with all State and County regulations.

The District is governed by a Board of Commissioners consisting of three elected officials who are residents of the service area. Our staff provides 24/7 service and responds to approximately 30-40 service calls weekly. We prioritize infrastructure investment and quality service without borrowing or paying interest.

For water quality concerns or questions about this report, please contact our Superintendent, Richard J. Passariello, at (516) 621-7770.
