What Bensenville homeowners actually face
Bensenville is a village of about 18,000 people in DuPage County, and its water comes from Lake Michigan. The City of Chicago treats it, the DuPage Water Commission carries it here, and the Village Public Works Utilities Division distributes it. If a supply line fails inside your house, that distinction matters little, but it does tell you who to call about the street side of the meter: Public Works at (630) 350-3435.
Flooding here has three separate sources. The Village lists Willow Creek, Silver Creek (also called Bensenville Ditch) and Addison Creek with its tributaries, each with its own floodplain, and it says plainly that it cannot prevent flooding. Before you decide on flood cover or a basement project, ask the Village Engineering Division whether your lot sits in one of those floodplains and check the FEMA flood map for your address.
Rain can overwhelm this region quickly. O'Hare, next door, recorded 5.55 inches over April 17 and 18, 2013, a record April two-day total for Chicago. That is regional context, not a claim about any one street, but it shows why sump pumps, window wells and floor drains deserve a test before spring storms rather than after.
About half of Bensenville homes are rentals, against roughly 73 percent owner-occupied across DuPage County. When water arrives in a rented unit, the tenant usually makes the first call and the landlord handles the repair and the policy, so both should photograph the damage and keep the dates of every message.
