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.
