Drains & sewer in Baton Rouge: what's different

Baton Rouge sits on flat, low ground near the Mississippi, so drainage depends heavily on clear sewers and canals. Heavy rain floods low areas and backs up sewers, and many homes added backwater valves after the 2016 flood.

Live oaks along older streets send roots into clay laterals, and homes near LSU and in the Garden District have older cast-iron drains.

The City-Parish provides sewer service, and permits come from the Department of Development. Louisiana requires state-licensed plumbers.

Drains & sewer questions in Baton Rouge

Should I add a backwater valve in Baton Rouge?

Many homes did after the 2016 flood. It keeps sewer water out when the system is overloaded.

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.
