The Plainview Water District has the responsibility to supply clean, safe, potable water to our consumers. We must implement, administer, and maintain ongoing backflow prevention and cross-connection control programs as required by the New York State Sanitary Code (Section 5-1.31) and enforced by the Nassau County Department of Health. This is done to protect the public water system from hazards originating on the premises of our customers and from temporary connections that may impair or alter the quality of the water in the public water system. A backflow condition may arise when very low or negative street pressure occurs due to water main breaks, hydrants knocked over, etc. The danger arises when there is a connection to the water source where water can be drawn back into the pipes. Backflow prevention devices must be used to stop such contaminants from potentially entering the public water system. The return of any water to the public water system after the water has been used for any purpose on a customer’s premises or within the customer’s piping system is unacceptable.
It is the policy of the District to follow and enforce the New York State Sanitary Code and the Nassau County Department of Health regulations concerning backflow prevention in order to protect the public water system. Consumers are required to adhere to the requirements set forth in the District’s Ordinances and all applicable Federal, State, and local regulatory requirements.
The law requires ALL backflow devices to be tested each year by a New York State Certified Backflow Tester and the results need to be filed with the Plainview Water District, as well as the Nassau County Department of Health. The form must be completed in its entirety otherwise it will be rejected.
