Drains & sewer in New Orleans, LA

Drains & sewer services in New Orleans

Local conditions

Drains & sewer in New Orleans: what's different

New Orleans sits below or near sea level in many areas, and settling soil cracks and separates buried sewer lines. Heavy rain floods streets quickly, and the city's drainage pumps and canals can be overwhelmed, backing up drains.

Raised shotgun houses and Creole cottages in Uptown, Bywater and the Marigny have plumbing under the house, while many homes were rebuilt after Hurricane Katrina with new plumbing connected to older lines. The Sewerage and Water Board maintains the public system, and permits come from the Department of Safety and Permits.

Drains & sewer questions in New Orleans

Why do New Orleans sewer lines break?

Subsidence. Soft soils settle over time, cracking and separating buried lines, especially where new plumbing meets old connections.

Are chemical drain cleaners safe to use?

They can damage older pipes and fixtures, and they make the job hazardous for the plumber if they don't work. A plunger or a drain snake is safer for a single slow drain.
