About Suffolk County Water Authority Inc

Sufficient to say, Suffolk County Water Authority makes sure that there is potable water across Long Island in addition to the seawater that surrounds it. The utility provides water services to about 1.2 million people in New York's Suffolk County, on the eastern end of Long Island. The water authority's system (the largest water system in the nation operating entirely with groundwater) includes more than 5,500 miles of mains. The authority also runs the largest groundwater testing facility in the US. Suffolk County Water Authority is a public benefit corporation of the state of New York.

In 2010 the authority considered raising and spending $3.8 million to build an additional 17,763 feet of water main for existing residential customers that relied on point of use (local, off-system) treatment systems for water service. However, to save costs and maintain a strong balance sheet it decided to cancel the project in 2011.

Increased water demand and higher water rates lifted Suffolk County Water Authority's revenues in 2011, and allowed the authority to post a positive operating income figure, after a couple of years of losses.

Suffolk County Water Authority was founded in 1951 with 21,159 customers, when the not-for-profit corporation acquired South Bay Consolidated Water Company.
