Sewer Line Repair in Towson, MD
In Towson the sewer lateral — the run from the house to the public main — belongs to whoever owns the property, not to the utility. There are 18,083 occupied homes here, and across all the housing the median build year is 1969 — the best single clue to what the pipe is made of and how it tends to fail.
In short
Orangeburg cannot be ruled out by date in Towson, where housing typically dates from 1969 and the plumbing code still permitted bituminized fiber. What settles it is whether the pipe still holds a round section.

What went in the ground around 1969
A lateral laid in Towson in that period is most likely Orangeburg or cast iron, with clay still going in at some depths. Which of the three you have is not something the build year can settle on its own. More on Orangeburg pipe.
What a camera survey should settle here
Three materials were going in the ground at once in these years, so the survey is identifying the pipe before it diagnoses anything. The full picture on Orangeburg pipe.
Towson is the 22nd largest block of laterals we cover in Maryland, carrying about 1.2% of the 1,481,205 homes on our MD list, and its housing runs older than 85% of the MD towns we route. Age concentration matters on a lateral: where a whole street went in one season, the failures arrive in one season too.
55% of homes here are owner-occupied — 14 points below the MD figure. That matters more on a lateral than on almost any other pipe in the house: the run from the building to the main is the property owner’s to repair, and a landlord and a resident owner do not find that out at the same speed.
Median household income across Towson ZIP codes is $95,772 — the relevant figure for a job no insurer and no utility is going to split.

Before anyone digs in Towson, get the run on camera — and ask what the pipe is actually made of, because the build year cannot settle it at this age. What the recording should show you.
