Dunn's sewer system and older homes

The City of Dunn operates its own wastewater treatment at the Black River facility, permitted for 3.75 MGD with a 7.50 MGD peak. The City maintains about 88 miles of sewer lines and aims to clean at least 10% of that system each year. Its water and sewer department also says City crews make sewer taps for new homes and repair sewer services and mains. Before you hire anyone for a replacement, call the City and ask where its responsibility for your service stops, since a problem at the tap may be theirs.

Age is what sets Dunn apart from the fast-growing Wake suburbs. The median home here was built in 1973, about two-thirds were built before 1980, and only about 9% since 2000, according to ACS 2019-2023 estimates. Houses around the downtown commercial district and older streets off Clinton Avenue and Cumberland Street are likely to have their first lateral, often clay or cast iron, and those pipes tend to fail along their whole length rather than in one spot. Replacing a run like that once is usually better than chasing joint after joint.

Rain is another tell. When a cracked clay line sits in wet ground, groundwater seeps in through the gaps, and drains that only slow down after a storm often point to a lateral that's open at the joints. A camera run during or just after wet weather can make those leaks easy to see.

What affects the cost

• Run length and depth from the foundation to the City connection
• Method: an open trench, or trenchless bursting or lining where the pipe is still on grade
• Obstacles: old trees, driveways and porches on older lots
• Condition at the house: some older homes need cast iron replaced under the floor too

After you call

We'll connect you with an independent local plumber who works in Dunn. A camera inspection usually comes first. Permits go through City of Dunn Planning & Inspections, which uses Cloud Permit online; the City's page doesn't list plumbing permits separately, so the plumber will confirm the steps and schedule the inspection before backfill.
