Received an NYC DEP Backflow Notice? Here's What Property Owners Should Know

NYC DEP oversees backflow prevention requirements intended to protect the city's water supply.

A property owner may receive correspondence concerning annual testing, missing documentation, required installation, or another issue involving a backflow prevention device.

Not every notice means the same thing.

The most important first step is to understand what the specific correspondence requires.

Identify the property address, referenced device or system, stated compliance issue, and any response deadline.

Determine whether the notice concerns an existing device, an annual testing requirement, missing documentation, or a broader installation issue.

Avoid assuming that scheduling a routine annual test will resolve every type of notice.

Different situations may require different professionals and documentation.

If a required annual test was not completed, the property owner should arrange appropriate testing and ensure the required report is submitted.

NYC DEP warns that failure to comply with annual testing requirements may lead to fines or water service disconnection.

Addressing the issue promptly can help prevent additional complications.

Locate any available testing documentation and review the submission status.

A previously completed test and a properly recorded compliance submission are not necessarily the same thing.

Depending on the circumstances, additional documentation or communication with DEP may be necessary.

A new installation follows a different process from routine annual testing.

DEP generally requires approved plans prepared by a Professional Engineer or Registered Architect, installation by a Licensed Master Plumber, and initial testing by a New York State certified tester.

AquaAudit can help property owners understand the process and coordinate next steps, but physical installation work must be completed by the appropriate licensed professionals.

Keep copies of correspondence, testing reports, and related documentation.

Track any deadlines and confirm that the appropriate follow-up steps have been completed.
