In Sanford, a sewer line that backs up or keeps clogging is often an older pipe with roots, cracks or a sag, since about 44% of homes were built before 1980. A camera inspection shows the cause and location. Call the number on this page to be connected with a local plumber in Sanford.
Who runs Sanford's sewer now?
Since July 1, 2024, TriRiver Water has been the water and wastewater provider for Sanford, replacing what used to be the City of Sanford's own utility. TriRiver also serves Pittsboro, and Siler City and most of Chatham County joined in July 2025. Sanford's wastewater is treated at the Big Buffalo plant, which has about 12 MGD of capacity and discharges to the Deep River.
For homeowners, the practical point is that problems with the public sewer main or the connection at the street now go to TriRiver Water, not the City. The fact sheets don't show where TriRiver's responsibility ends on a service line, so if a camera shows the trouble near the street, call TriRiver before paying for that part of the work. Older bills and stickers may still say City of Sanford.
Why do older Sanford homes have more sewer trouble?
Sanford is the Lee County seat and a longtime railroad and industrial city, known as the Brick Capital of the USA. Its housing is older than the Wake County suburbs: median build year 1985, with about 44% of homes built before 1980. Homes in the Downtown Sanford and Rosemount-McIver Park historic districts are typical of the older stock.
Sewer pipe from before 1980 is often clay or cast iron. Clay pipe comes in short sections with many joints, and roots can work into each one. Cast iron corrodes from the inside and can crack or flake until it catches waste. Lines that old have also had time to settle and develop low spots. Newer homes have plastic pipe, where the usual problems are sags, separated joints and blockages.
Who issues permits for a sewer repair?
The City of Sanford / Lee County Inspections Division serves Sanford, Broadway and Lee County, and permits are applied for online through its CSS portal. The plumber doing the repair normally knows when a permit is needed and handles the application. Ask about it when you discuss the repair plan, especially for any work that involves digging up and replacing pipe.
A note for Sanford homeowners
Because the utility name changed recently, it helps to have a current TriRiver Water bill handy when you call, in case the plumber needs to know your service details or you need to contact TriRiver about the public side. Before the visit, find any outside cleanout and note which drains backed up first.
