In Berwyn, the flood maps lie — or at least, they don't tell the story. When flooding swamped Berwyn from April 16 to May 5, 2013 — storm sewers at capacity, sewer lines failing, backups pouring into homes — the city reported 87 homes and 3 public schools affected. President Obama declared a major disaster (DR-4116), and Individual Assistance payments to Berwyn residents totaled $1,267,203 across 303 claims. And yet a 2015 Illinois study found that 90% of damage claims were outside the mapped 100-year floodplain. The water wasn't coming from a river. It was coming up through the pipes.
That's the defining fact of the "City of Homes." Berwyn runs on a combined sewer system — stormwater and sanitary sewage in a single pipe — and sits at the downstream end of MWRD's interceptor system to the Stickney Water Reclamation Plant, where capacity runs out first. The 1920s bungalows that made Berwyn the fastest-growing community in America are still here — 1,109 brick Chicago bungalows in the historic district alone. Old brick, old pipes, one overloaded system. When yours backs up, call (773) 200-3228. Rapid Water Damage Restoration Illinois answers 24/7.
Our Berwyn water damage services
Emergency water extraction. Combined-sewer backup, stormwater intrusion, or a burst pipe in a century-old bungalow — truck-mounted pumps and portable extractors clear basements fast, with containment where sewage is involved.
Structural drying and dehumidification. Berwyn's 1900–1949 housing stock — brick bungalows with plaster, hardwood, aging framing — holds moisture long after surfaces look dry. We verify with daily moisture-meter readings until every material tests dry.
Mold remediation. Backup water soaking into finished basements and wall cavities is how mold takes hold. We contain affected areas, remove contaminated materials, and treat surfaces to IICRC standards.
Sewage cleanup. Berwyn's signature event: when the combined system surcharges, Category 3 water backs into basements. We extract in full PPE, remove unsalvageable materials, and disinfect every affected surface.
Storm damage repair. Wind-driven rain through damaged roofs and siding, plus repairs after severe-storm flooding — we secure the structure, extract, dry, and rebuild to pre-loss condition.
Common causes of water damage in Berwyn
- Combined-sewer surcharge. The whole city runs on one pipe for stormwater and sewage. In heavy rain, capacity is easily exceeded — and sewage and stormwater back into basements and streets.
- The downstream-end problem. Berwyn sits at the downstream end of MWRD's interceptor system to Stickney, so the interceptor often lacks capacity for the city's runoff — which means TARP and the McCook Reservoir can provide only limited relief here.
- An aging, brick-built network. The 2014 Wastewater Facility Plan notes the trunk sewer down Oak Park Avenue is brick construction — and much of the network is dated. Century-old brick sewers crack, infiltrate, and constrict.
- High groundwater seepage. Beyond backups, seepage from high groundwater is a documented concern — hydrostatic pressure pushing water through foundation walls and floors even when the sewers behave.
- Low-lying viaduct streets. Streets beneath the Canadian National viaducts at Oak Park Avenue and East Avenue sit low and likely flood in major storms; Public Works routinely checks and clears them.
Our restoration process in Berwyn
- Call (773) 200-3228 — we're here around the clock. Sewage in the basement, stormwater at the foundation, or a burst pipe. In Berwyn, the first question is always whether it's a backup, because that changes everything.
- We identify the water and contain it. Combined-sewer backup, groundwater seepage, or clean supply water — each gets its own protocol. Sewage jobs get full containment and disinfection from the start.
- We extract and remove. Standing water is pumped out; contaminated porous materials — carpet, pad, soaked drywall — are removed for safe disposal.
- We dry and verify. Air movers and dehumidifiers run until moisture meters confirm plaster, framing, and masonry are dry.
- We rebuild and document. Damaged finishes are restored to pre-loss condition, and every photo, moisture reading, and line item is compiled for your adjuster. We walk the job with you.

Cost factors & insurance claim help
We never quote by phone — every Berwyn loss is scoped on its facts: the water category, how much finished space was affected and for how long, and the home's age and materials. Two coverage questions come up constantly: sewer-backup coverage typically depends on a backup endorsement, and the 2013 lesson — 90% of claims outside the mapped floodplain — is worth remembering. The city's Engineering Division has promoted a Residential Flood Mitigation Shared Cost Program (reported as 50% cost sharing up to $3,500 for qualifying installations) — confirm current details with the city first. We photograph and log everything, review your coverage with you, and work directly with your insurance company from first call to final walkthrough. Call (773) 200-3228 to get started.
Frequently asked questions
How could 90% of Berwyn's damage claims fall outside the 100-year floodplain?
Berwyn's flooding is urban, not riverine. A 2015 Illinois study found 90% of claims were outside the mapped floodplain — the water comes from combined-sewer surcharge and overland runoff, which don't respect floodplain maps.
What was the April–May 2013 flood like?
Storm sewers at capacity, sewer lines failing, backups flooding into homes. Berwyn reported 87 homes and 3 public schools affected; President Obama declared major disaster DR-4116, and Individual Assistance payments totaled $1,267,203 across 303 claims.
Why doesn't the Deep Tunnel save Berwyn?
Berwyn sits at the downstream end of MWRD's interceptor system to Stickney, where the interceptor often lacks capacity for the city's runoff. That bottleneck means TARP and the McCook Reservoir can provide only limited relief here.
What is the city's Residential Flood Mitigation Shared Cost Program?
Berwyn's Engineering Division has promoted 50% cost sharing up to $3,500 for qualifying overhead sewers, backflow valves with bypass pumps, or comparable measures. This is reported by a plumbing-industry source, not the city's own published materials — confirm current details with the city's Engineering Division before applying.
My Berwyn brick bungalow was built in the 1920s. What should I know about its water risk?
It's original — and so is much of its plumbing. The district's 1,109 brick bungalows were built 1900–1949, mostly in the mid-1920s, and century-old lines corrode and burst on schedule. Add the aging brick trunk sewer down Oak Park Avenue and high-groundwater seepage.
