Plumbing help in Evanston
Evanston’s housing is among the oldest in the region, and much of the city is served by combined sewers. Basement backup protection and old building sewers are recurring themes.
Calls are answered by a referral service that connects you with a local plumbing provider. How this works
Evanston homes
Evanston (78,110 residents, 2020 Census) borders Chicago’s Rogers Park. One ACS-based estimate puts about 42% of its housing units as built in 1939 or earlier.
| Home type | Plumbing themes |
|---|---|
| Large pre-1940 houses | Cast-iron drains, long building sewers, mature parkway trees |
| Vintage courtyard and walk-up apartments | Shared risers and stacks; management approvals |
| Two-flats | Shared building sewer; garden units |
| Mid-century homes (west and north) | Basement drains; sump systems in some |
Patterns only.
Common needs
Overhead sewers
A common protection in combined-sewer areas. Overhead sewers in Evanston
Old building sewers
Roots and cracks under parkway trees. Camera inspection
Backflow devices
Cross-connection control has its own City program (C3).
- Ejector pump with check valve lifts basement wastewater up; it needs power, so outages matter.
- Overhead sewer line runs near the basement ceiling.
- Building sewer exits the wall at a higher elevation.
- Former floor-level openings are sealed under the design.
Local programs
Evanston has a combined sewer system.
The City publishes a Sewer Repair Financial Assistance Program for residents with a private sewer lateral repair in the City right-of-way; the application asks for a recent W-2 and the contractor’s sewer work documentation.

What we could not confirm
- Current eligibility limits and assistance amounts for the sewer repair program.
- Whether Evanston currently offers an overhead-sewer cost share.
Check with the official source before relying on these points.
Evanston permits
All contractors working under a City of Evanston permit must be registered with the City; licensed plumbers (State licenses) are not registration-eligible, because plumber licensing is a State function.

Backflow prevention devices need a permit for each device, and testing is done by City-licensed C3 contractors holding an Illinois EPA cross-connection inspector license.
