Who do I call for a clogged sewer line in Harrisburg, PA?
If one sink or toilet is slow, a plunger usually does it. If sewage is rising in the basement floor drain, several fixtures are backing up together, or it happens every time it rains hard, the clog is usually in your sewer lateral. Capital Region Water says that line, from your home to its main, is the property owner’s to maintain and repair. If the whole street is affected, call Capital Region Water. If it’s only your home, call (888) 703-1520 for a local drain pro who confirms the price before starting.
What part of the sewer line does a Harrisburg homeowner own?
- The lateral is yours. Capital Region Water says sewer laterals, running from the home to its mains, are the property owner’s responsibility.
- The main is theirs. Capital Region Water owns the mains that connect every lateral to its treatment plant.
- Shared lines. Some older rowhomes share one private “party line.” Neighbors settle repairs between themselves, or can ask to be connected directly to a main at their own expense.
- Repairs on notice. The City code requires owners or occupants to repair leaks or breaks in the pipes connecting their property to the sewer within 72 hours after notice.
Can Capital Region Water help pay for a lateral repair?
If a camera shows the break is under the sidewalk or street, ask about Capital Region Water’s Service Line and Lateral Assistance Program:
- It can cover the lateral section in the public right of way, from the curb line or cleanout to the main.
- It does not cover the part under your own yard or house.
- You apply before the repair, with two written quotes from licensed contractors that split public and private costs.
- Approved help is paid directly to the contractor. Eligibility requirements apply.
Capital Region Water notes that line failures can cost upwards of $5,000 or $10,000, so a camera inspection that shows exactly where the problem is can save real money.
Why Harrisburg drains clog
An old housing stock
About 43% of Harrisburg homes were built before 1940 and another 10% in the 1940s; the median home dates to 1947. Clay laterals and cast-iron drains from that era crack, scale up and let roots in.
Combined sewers
About 60% of the city drains into combined sewers that carry sewage and stormwater in the same pipes. Downspouts or foundation drains tied into a lateral add rainwater the line can’t handle.
Mostly renters
About 63% of Harrisburg homes are rented, many in rowhomes and converted houses. Grease, wipes and shared party lines are a common recipe for repeat clogs.

Do plumbers clean out drains in Harrisburg?
Yes, but clearing a sewer lateral is specialized work. Plenty of people search for a plumber in Harrisburg when what they need is a drain pro with the right machine:
- Cable machine: cuts through roots, paper and grease to reopen the lateral.
- Hydro jetting: scours grease and scale from old pipe walls so the line stays open longer.
- Sewer camera: shows whether the problem is a clog, a crack, a sag or a shared line, and whether it’s on your side or under the street.
Skip the chemical drain cleaners in a backed-up line; they rarely reach a main-line clog.
How much does drain cleaning cost in Harrisburg?
It depends on which line is clogged, how the pro reaches it, what caused it and when you call. A bathroom sink is quick; a root-packed lateral under a 1920s rowhome takes a bigger machine and often a camera. When you call (888) 703-1520, the price is confirmed before any work starts.

Why does my Harrisburg basement drain back up when it rains?
About 60% of Harrisburg is on combined sewers, which carry sewage and stormwater together. In heavy rain the system fills, and if your lateral is partly blocked or a downspout is tied into it, water backs up through the lowest drain, usually in the basement.
