Basement Backups After Heavy Rain in Harrisburg
What storms do to older city sewers, and what homeowners can do.
Published November 5, 2026 · Harrisburg Drain Clean
When sewage comes up in the basement, the first question is whose problem it is. In Harrisburg the answer depends on where the blockage sits.

Capital Region Water (CRW) is responsible for the water and wastewater mains under the streets. CRW says property owners are responsible for their drinking water service line and their sewer lateral, including keeping them working and repairing them.
The lateral is the pipe that carries everything from your house to the main. It starts at your building drain, usually in the basement, and runs under the yard or sidewalk to the street.

Call 24/7 (717) 459-0752CRW suggests having a licensed plumber inspect your lines, including a video inspection of the sewer. A camera shows roots, cracks and sags before they turn into a backup.
If sewage is overflowing from a manhole or out of the street, that is the public system. Contact Capital Region Water. If it is inside your house, start with a drain contractor.

Call 24/7 (717) 459-0752CRW has published guidance for a drinking water service line and wastewater lateral assistance program. Eligibility and funding change, so ask CRW directly.
The City of Harrisburg Bureau of Codes requires a permit for installing or replacing plumbing pipes, done by a master plumber licensed to work in the city.
Tenants usually report the problem to the landlord, who arranges the repair. Report early: a slow drain is cheaper to fix than a flooded basement.

Call 24/7 (717) 459-0752Most Harrisburg laterals connect to a main under the street. The connection point, sometimes called the tap, is where the private lateral meets the public pipe. CRW's guidance places responsibility for the lateral on the property owner, so the run up to that connection is the owner's to maintain.
Exact details can depend on the property, so if a repair is near the main, ask the provider and CRW how the work is divided.
A homeowner notices slow drains, then a basement floor drain backup. A provider clears the line from the basement cleanout and finds roots. A camera shows a cracked clay joint under the sidewalk. The owner decides between periodic cleaning and a repair. That is the most common story in Harrisburg, and every step of it falls on the owner's side.
Find your cleanout now, before an emergency. Keep the name and license number of a plumber you trust. If you have had camera footage taken, store it. And if your line has a history, consider scheduled maintenance so it does not choose the worst moment to back up.

Call 24/7 (717) 459-0752For anything involving the public main, a manhole, a street overflow or the assistance program, contact CRW directly. Their staff can tell you what they cover and what they do not.
Many homeowners assume the utility handles everything outside the house. In Harrisburg, CRW maintains the mains, while the lateral that serves your property is yours. Knowing that saves time when you need help.
Another misunderstanding is that a backup during a storm must be the utility's fault. Storms stress the public system, but the condition of your lateral still matters. Clear, well-maintained laterals are less likely to back up.

Call 24/7 (717) 459-0752Sewage on your basement floor: drain contractor. Slow drains throughout the house: drain contractor. Roots in your lateral: drain contractor, then repair. Manhole overflowing in the street: Capital Region Water. A permit for replacing pipe: the licensed plumber, through the city.
Keeping that list in mind makes the first call the right one.
Because the lateral is yours, so is the cost of keeping it working. Setting aside a small amount each year for drain maintenance, and getting an inspection every few years in an older home, spreads that cost out and avoids a sudden large bill. Checking with CRW about assistance programs is worthwhile if a large repair comes up.
Find your cleanout today. In an emergency, knowing where it is saves time for you and the provider.
