The Town of Hempstead Water department consists of six separate districts: Bowling Green Estates, East Meadow, Levittown, Uniondale, Roosevelt Field, Lido-Point Lookout. All other communities in the Town of Hempstead are serviced by either private companies or villages.
The department offers tours and lectures at its East Meadow facility. This service is available to schools and senior groups, among others.
Water supply for the districts is drawn from 32 wells, of which 29 are located in the Magothy Aquifer. Three of the 32 wells are located in the Lido-Pt. Lookout Water District and are drawn from the deeper Lloyd formation. Wells range in depth from 487' to 1,285' and were installed between 1951 and 2012.
In 2017, the 32 wells produced 6,520,784,000 gallons (including Lido) of water. To deliver water to the department's 37,763 customers, there are 377 miles of water mains, ranging in size from 6" to 24" in diameter. The department has seven elevated and two ground storage tanks with a storage capacity of nine million gallons. In addition, the department maintains 3,317 fire hydrants.
In 2017, the average residential customer used approximately 141,417 gallons of water, a daily average of 387 gallons. All of the departments water meters are equipped to be read via a remote reading terminal, thus eliminating the need to enter a customer's home.
The Water Department routinely samples district wells and the distribution system. Laboratory tests were performed on thousands of water quality samples collected in 2017. These tests monitor various inorganic, organic and microbiological constituents listed in the New York State's drinking water standards. All tests performed at district wells and from the distribution system met all of the current state and federal drinking water standards.
