Sewer Line Replacement in Lillington, NC

Lillington runs its own sewer collection lines, with treatment handled by Harnett County's utility, and town crews say they work only in the public right-of-way. That leaves the private lateral to the homeowner and a private plumber. Call the number on this page to be connected with a local plumber in Lillington.

How Lillington divides the work

The Town of Lillington owns the sewer collection system, and Harnett County's utility, now Harnett Regional Water, provides bulk treatment, according to a 2018 county presentation. The town's public works page says its crews work on lines in the town right-of-way and don't work on private lines past the meter, and that lines between the meter box and the home need a private plumber. That statement is about water lines, but it reflects the same approach on sewer: the pipe on your property is your responsibility. Ask the town where your lateral meets its sewer before work starts.

Lillington's housing has a split personality. About 31% of homes were built before 1980, yet the median home dates to 2005 and roughly 46% were built in 2010 or later, per ACS 2019-2023 estimates. The older houses near Main Street (US 401) and the county courthouse are where original clay and cast iron laterals are most likely. Newer subdivisions such as Vandercroft and RiverBluff have plastic pipe, which fails differently.

Timing and permits

Lillington Planning & Inspections handles building inspections inside town limits and the ETJ, and offers next-day inspections through its inspections line; outside that area, Harnett County Inspections applies. Since the trench can't be closed until it's inspected, plan for that step. Dry weather makes the digging and cleanup easier, especially on clay soil.

If you're in one of the newer subdivisions and the house is only a few years old, check whether a builder warranty still covers the sewer line before paying for work. On older homes near downtown, ask the plumber whether any cast iron under the house should be replaced at the same time, since it's usually the same age as the yard line.
