NYC Law: Your Sewer Line, Your Responsibility

Property owners are legally responsible for sewer lines from the building foundation to the city’s main connection beneath the street. New York City requires you to hire licensed contractors when deterioration demands replacement, and you remain accountable for code compliance. 

Harris Water Main & Sewer Contractors helps you navigate these obligations. We coordinate Department of Environmental Protection (DEP) permits, schedule inspections and confirm that installations meet all regulatory standards.

Signs You Need a Sewer Line Replacement

A complete NYC sewer replacement becomes necessary when deterioration affects multiple sections or materials can no longer function reliably. Some signs include:

  • Repeated failures after repairs: Persistent backups can indicate damage beyond the scope of targeted fixes.
  • Outdated pipe materials: Clay and early cast-iron lines may crack and separate along their length as materials degrade.
  • Continuous root penetration: Joints and pipe walls that experience repeated root infiltration may lose structural integrity.
  • Major property transactions: Building sales or substantial renovations can justify eliminating aging infrastructure that creates future liability.

Our experts provide an honest assessment of your sewer line. We recommend replacements when repairs cannot deliver the long-term productivity your building requires.

Great job. Thank you.

Jacob Melinger

The workers were personable, and did their job well, with only one issue. The issue being, the toilet does not seem to be working after the apartment's water supply was restored. However, that may be an issue to discuss with the landlord, rather than the plumbing company, itself. I will edit this review accordingly, when I have the answer.
