NYC DEP Approved Contractor

What Is a NYC DEP Approved Contractor?

The NYC Department of Environmental Protection (DEP) oversees all sewer and water main work in New York City. A DEP approved contractor has demonstrated the qualifications, experience, and compliance history necessary to perform sewer and water main work to DEP standards. This includes holding a valid NYC Master Plumber License, maintaining proper insurance, following DEP specifications for materials and installation methods, and having a track record of passing DEP inspections. Sewer & Water Pros is a fully certified NYC DEP contractor with over 20 years of successful DEP compliance.

Why DEP Certification Matters

Hiring a DEP certified contractor is not optional — it is required by law for all sewer and water main work in NYC. But beyond the legal requirement, DEP certification matters because it ensures your contractor knows the specific NYC standards for pipe materials, installation depths, slope requirements, connection specifications, and inspection procedures. A DEP certified contractor also has established relationships with DEP inspectors, which means smoother inspections, fewer delays, and faster project completion. Sewer & Water Pros has maintained a 98%+ first-time inspection pass rate over the past decade.
