Naperville's newer homes usually have PVC laterals that resist roots, but bellies (sags) and grease clogs still happen. Older homes near downtown may have clay. Either way, start with a camera inspection before agreeing to a big repair.
Who's responsible for the sewer line in Naperville
Naperville says homeowners maintain the sanitary service line from the house to the main; the City handles defects and total blockages in the right-of-way. During a backup, especially after heavy rain, call the City's Water Utility first so it can check the main line. The City has also offered a reimbursement program for backflow-prevention devices when a backup was caused by a surcharged public sewer — check the City's page for current terms.
Program terms come from the official page linked below as published when we checked in October 2026. Funding and rules change, so confirm with the village or district before work starts — most programs require approval before you hire.
Housing age in Naperville
About 149,540 people lived in Naperville in the 2020 Census. The median home there was built around 1990, and the biggest share of its housing went up between 1990 and 2009 (11% before 1970, 40% from 1970–1989, 41% from 1990–2009, 8% since 2010). Roughly 63% of homes are detached single-family houses and 12% are townhouses or other attached single-family homes; about 75% of households own their home.
Many Naperville homes (40%) date from 1970–1989. Sewer pipe materials changed over those years, so the only way to know what's in your yard is a camera inspection — ask the plumber for a copy of the video, since several village programs require it.
We refer sewer work only to licensed plumbers. Illinois' Plumbing License Law generally requires an Illinois-licensed plumber for this work, and digging in the parkway usually needs a village permit — the plumber should pull it.
