Backflow prevention devices prevent hazardous substances from entering our public water
supply. The New York State Department of Health implements the requirements for this program through the Nassau county Department
of Health and local water suppliers. Nassau County Health ordinance Article VI, Section 15(b)(1) requires that we discontinue water
service to those users who have failed to properly install, maintain, and test a backflow prevention device.
The District recently amended its Rules and Regulations regarding the annual testing requirement of these devices. Only those homes with
underground sprinkler systems are now required to submit annual tests. Homeowner's without underground sprinklers can call the
District for a waiver from the annual testing requirement.
Additionally, homeowner's with sprinkler systems can also eliminate the annual testing requirement by installing a pressure vacuum breaker (PVB).
If you would like more information regarding the installation of a PVB, please contact Marshall Brandt at 516-466-4413.
In New York State, individuals who test backflow prevention
devices for the purpose of protecting the public water supply are
required to hold a valid certification issued pursuant to 10 NYCRR
Section 5-1.31. Below is a current list of New York State certified
backflow prevention device testers. For more information on
contacting any of these individuals, please contact your
County Health Department or State District Office, or email the
Bureau of Water Supply

L.I. Water Conference Assures High Water Quality
The Long Island Water Conference assures residents that
there has been no lead contamination in their water supply for
over 30 years. All Long Island water providers exhaustively test
and treat for lead content. To ensure the water supply is not
contaminated with lead, all Long Island water suppliers comply
with the United States Environmental Protection Agency’s (USEPA)
