Elmhurst has many older homes with basement floor drains and older foundations. Water on the floor after a big storm can be groundwater seepage or a sewer backup — they need very different fixes. If water is coming up the floor drain, talk to a plumber about backflow prevention; if it's coming through walls, a waterproofing contractor is the right call. Elmhurst has run flood-control assistance programs; check the city site for current offerings.

Wet basement or sewer backup? Know which one you have

Groundwater seeping through walls or the floor is a waterproofing problem (drain tile, sump pump, crack repair). Water coming up through a floor drain during heavy rain is often a sewer backup, which calls for backflow protection or an overhead sewer. Many Elmhurst homeowners need to know which before paying for a fix.

What Elmhurst offers homeowners

Elmhurst runs an Overhead Sewer Program that shares 50% of eligible costs, up to $5,000, to convert a gravity sewer to an overhead sewer that protects the basement from backups. It needs a City permit and drawings, and the perimeter drain tile has to be disconnected from the sanitary sewer and sent to a sump pump.

Housing in Elmhurst

About 45,786 people lived in Elmhurst in the 2020 Census. The median home there was built around 1966, and the biggest share of its housing went up before 1970 (55% before 1970, 15% from 1970–1989, 19% from 1990–2009, 11% since 2010). Roughly 72% of homes are detached single-family houses and 5% are townhouses or other attached single-family homes; about 80% of households own their home.

Older Elmhurst homes (55% pre-1970) are more likely to have block or poured walls with old clay drain tile and floor drains tied into the sewer. Several DuPage programs require disconnecting drain tile from the sanitary sewer and sending it to a sump pump — a common part of waterproofing jobs here.

Ask any waterproofing contractor for a written diagnosis of where the water is coming from, what they'll fix, and whether a village permit is needed.
