Sewer Line Replacement in Takoma Park, MD

Why do so many Takoma Park sewer lines need replacing?

Takoma Park was laid out in 1883 as a Victorian-era commuter suburb on the District line, and much of it is a National Register historic district. The median home was built in 1954, and many are far older. Sewer laterals from those decades were often clay or cast iron. Clay joints separate and let roots in, and cast iron rusts from the inside until it cracks or loses its bottom. When those problems show up along much of the run, patching one spot just moves the next backup down the line.

What role do the trees play?

A big one. The city is known as Azalea City and has a heavy tree canopy, and Sligo Creek Park runs through it. Roots don't usually break sound pipe, but they find any crack or loose joint and fill the pipe from the inside. A camera inspection shows whether roots are entering at one point or many. When it's many, replacement or a full-length liner is usually the lasting answer. Ask the plumber about trenchless methods where the route passes close to large trees, since they disturb less of the root zone than a long trench.

Who signs off on the work?

WSSC Water is the sewer utility and issues plumbing permits here; replacing a water or sewer service line is work for a plumber registered with WSSC Water. Takoma Park is an incorporated city, and Montgomery County handles building permits; WSSC lists the county's Land Development and Residential Permit Processing at 240-777-6323. If excavation touches the front yard, sidewalk or anything in the historic district beyond the pipe itself, ask the plumber or the city whether any additional review applies before digging.

A short local note

Takoma Park is a basement town, and older houses often have a floor drain at the lowest point. If that drain is where backups show up, ask about adding a backwater valve while the line is open. Report sewage in the street to WSSC Water's Emergency Service Center at 301-206-4002. If the backup is limited to your house, a plumber can usually clear it to keep things working while the replacement is planned.
