Why do you need backflow preventor filing with DEP in NYC? New York City Department of Environmental Protection - BFV - DCDA - RPZ

Updated: Jun 28

In New York City, backflow filing with the Department of Environmental Protection (DEP) is required to ensure the safety and quality of the city's drinking water supply. Backflow occurs when water flows in the opposite direction than intended, potentially allowing contaminants or pollutants to enter the drinking water system.

The DEP mandates backflow prevention measures to protect against this risk, especially in buildings where there are potential cross-connections between the drinking water supply and sources of contamination (such as heating systems, irrigation systems, or industrial processes).

Filing with the DEP involves documenting and maintaining records of backflow prevention devices and systems, ensuring they are installed correctly, tested regularly, and meet the required standards. This helps ensure that the water supplied to residents and businesses in NYC remains safe and free from contaminants, safeguarding public health.
