Sewer backup or slow drains in Westmont? Below is what public data says about Westmont's homes, the local rules that matter, and how to get matched with one licensed local pro for free.

Who's responsible for the sewer line in Westmont

Westmont's sanitary sewers are run by two districts, not the Village: Downers Grove Sanitary District serves the area west of Cass Avenue and Flagg Creek Water Reclamation District serves the area east of Cass. Which one you're in decides who to call about the main and which assistance programs apply; the line on your property is yours to maintain.

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 Westmont

About 24,429 people lived in Westmont in the 2020 Census. The median home there was built around 1976, and the biggest share of its housing went up between 1970 and 1989 (32% before 1970, 43% from 1970–1989, 21% from 1990–2009, 3% since 2010). Roughly 41% of homes are detached single-family houses and 8% are townhouses or other attached single-family homes; about 55% of households own their home.

Many Westmont homes (43%) 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.
