Our Services

The Greenlawn Water District services a diverse Long Island community and supplies water to both residential and commercial sites. The District is capable of pumping in excess of 20 million gallons of water per day.

Delivering Mother Nature’s Finest

The Greenlawn Water District  pumps groundwater from far beneath the surface with our deepest well being 700+ feet, which reaches  into Long Island’s Magothy aquifer. This water is channeled into a distribution network consisting of some 200 miles of water mains. Connected to the distribution system are three elevated storage tanks and a 3,000,000-gallon ground storage tank. Total GWD storage exceeds 6,000,000 gallons.

Residential Services

GWD residents can be assured that the water you drink, bathe, wash and cook with is regularly tested and is completely compliant and meets or exceeds local, New York State and federal regulations.  We are proud to note the GWD’s water has been judged the Best Tasting Water in Suffolk County on numerous occasion, as well as the Best Tasting Water in New York State. And because our residents have local control, this high quality water  is available for you whenever you need it, to water a garden, wash your car, or to have a drink.

We believe in transparency with the public. As a resident, you are entitled to information. The Greenlawn Water District Commissioners and Superintendent Bob Santoriello (bob@greenlawnwater.org) maintain an open door policy to distribute information, though please be advised that this has been modified due to the COVID-19 pandemic. The full effects of  our open door policy is evident through our  annual water quality reports, newsletters, telephone and email access and special reports in addition to our updated website.  And, as GWD residents who are elected by voters, your commissioners always have the goals of  compliance, plentiful supply and keeping costs as low as possible.

Commercial Services

Currently, of the Greenlawn Water District’s 12,000 connections, approximately 5% are commercial in nature.  Commercial organizations can depend on the same quality and uninterrupted delivery of water as residents.
