Department of Environmental Protection

The NYC Department of Environmental Protection (DEP) manages the city’s water supply, sewers, wastewater treatment, and environmental rules to protect public health and the environment.​

DEP’s Role

DEP oversees drinking water delivery, sewage and stormwater systems, and enforces rules on air quality, noise, and hazardous materials across NYC. Homeowners interact with DEP mainly through water and sewer billing, permits for plumbing work, and conservation programs like free low-flow fixtures.​

Property Interference

DEP can issue violations and fines if homeowners cause leaks, sewer backups, or illegal discharges that pollute waterways or strain city infrastructure, such as faulty private pipes leading to street sinkholes. They may shut off water service for unpaid bills or hazards, require costly repairs to service lines up to the city main, or inspect properties in watersheds for easement compliance that limits land use.​

Homeowner Tips

Report issues like discolored water or clogged drains to 311 for DEP response, and get permits for any water/sewer work to avoid penalties. Maintain pipes to prevent DEP notices, and check for watershed rules if your property is outside city limits.
