Mount Prospect's Postwar Housing
Mount Prospect grew rapidly in the postwar boom, with ranch and split-level homes built through the 1950s and 60s on what was, at the time, modern PVC and clay piping. Mount Prospect's ZIP code (60056) covers the entire village.
Mature Trees on "Newer" Lines
Seventy-plus years is long enough for parkway trees planted when these subdivisions were new to send roots into joint gaps in the original clay laterals - see tree root removal for why "newer" construction doesn't mean root-free.
Kitchen Line Buildup in Ranch Homes
Single-story ranch layouts often route the kitchen line on a long, low-slope run, which grease can narrow over time - see grease line cleaning for how that gets cleared.
Busse’s Village and a Postwar Boom
Mount Prospect was settled in the 1830s and 1840s by German farmers, and the village got its start when real estate developer Ezra Eggleston platted a town around a Chicago and North Western railroad stop in 1874, naming it for its slightly elevated position on the prairie. For decades it remained a small farming village, with the Busse family prominent in local business and politics. Mount Prospect incorporated in 1917. After the Second World War it grew rapidly, and by the 1970s it had become a large suburb of ranches, Cape Cods, split-levels and later townhomes and condos. Its downtown along Northwest Highway and Main Street has been redeveloped with condo buildings near the Metra station.
Most Mount Prospect homes were built between the late 1940s and the 1970s, with a small number of older homes near downtown and newer construction on teardown lots. Plumbing typically includes cast iron drains and clay laterals now fifty to seventy-five years old. Weller Creek, Feehanville Ditch and clay soils shape drainage across the village.
Postwar Ranches, Cape Cods and Split-Levels
Mount Prospect's postwar homes typically have full basements or lower levels with floor drains and front-wall cleanouts. Split-levels often have lower-level bathrooms and laundry areas near sewer elevation, served by ejector pumps. When lower-level fixtures back up while upstairs drains work normally, the pump or its check valve is often the cause.
Trees planted when these neighborhoods were built are now large, and root intrusion into clay laterals is the leading cause of recurring backups. Rodding clears the line, a camera inspection shows how many joints are affected and lining provides a permanent fix.
Weller Creek and Flooding
Weller Creek runs through the southern part of Mount Prospect, and neighborhoods near it have experienced serious flooding during major storms, including those in 1987, 2008 and 2013. The village and the Metropolitan Water Reclamation District have built stormwater projects, reservoirs and channel improvements, but homes in low areas remain at risk during extreme rain. Sanitary sewers can be overloaded by infiltration, pushing sewage into basements.
Homes near the creek benefit from backwater valves or overhead sewers, sump pumps with battery backups, window well covers and flood-resistant basement finishes.
Older Homes and Downtown Condos
Older homes near downtown, some from the early twentieth century, may have clay laterals nearing a century old. New condo buildings near the Metra station have modern systems managed by associations, where kitchen stack maintenance is important. Restaurants downtown should maintain grease interceptors and schedule regular hydro jetting.
Sanitary Sewers and Backups
Mount Prospect's sanitary sewers are separate from storm sewers in most areas, but heavy rain can overload them through infiltration and improperly connected sump pumps or downspouts. A backwater valve protects your basement. If several homes on your street back up at once, contact village public works.
Clay Soils and Settling
Clay soils expand and contract with moisture and frost, and older clay laterals crack or separate while newer lines settle into sags. A recurring clog at the same spot often indicates a sag; a camera inspection confirms it.
Teardowns and New Homes
Some older Mount Prospect homes have been replaced with larger new houses. New service lines still connect to older public mains, so ask whether the lateral was replaced all the way to the main.
Buying in Mount Prospect
For postwar homes, schedule a sewer camera inspection before closing and ask about ejector pump age. Near Weller Creek, ask about flooding history and basement protection. For condos, ask about stack maintenance.
Everyday Habits
Keep grease out of kitchen drains, flush only toilet paper, use hair catchers in showers and clean the washing machine's lint screen. Keep the basement floor drain clear so early warning signs are easy to see.
Drainage Notes for Mount Prospect
Mount Prospect has a historic core around its Metra station, large postwar neighborhoods of ranches, Cape Cods and split-levels, and later townhomes and condo buildings downtown. Older homes have cast iron stacks and clay laterals under mature parkway trees, and postwar homes are reaching sixty to seventy years on their original laterals. Weller Creek and McDonald Creek cross the village, and several neighborhoods have experienced basement flooding in heavy storms, prompting storm water improvements. Root intrusion and storm backups are the most common problems. For finished basements, backwater valves or overhead sewer conversions provide the strongest protection. Condo buildings should keep maps of their shared lines.
For year-round upkeep that applies to most homes (sump and ejector pump testing, winter care, kitchen habits, warning signs and keeping service records), see the Drain Care Guide.
Service in Mount Prospect
Crews serving the northwest suburbs cover Mount Prospect along with Arlington Heights, Des Plaines, Prospect Heights, Elk Grove Village and Wheeling. When you call, share your address, the type of home and which fixtures are affected, and mention if you have a sump pump, ejector pump or backwater valve.
For main line clogs, the crew will rod from the most accessible cleanout. For older homes or recurring problems, a camera inspection is recommended. Pricing is confirmed on site before work begins.
Coverage Area
Local crews in our network serve the Village of Mount Prospect, including downtown near the Metra station, the neighborhoods along Weller Creek and the subdivisions along Rand Road, Central Road, Golf Road, Algonquin Road and Busse Road. Share your address and nearest cross streets when you call.
Randhurst and Commercial Corridors
Randhurst, which opened in 1962 as one of the largest enclosed shopping centers in the country and was later rebuilt as an open-air village, anchors Mount Prospect's northern commercial district. Restaurants and shops there and along Rand Road, Elmhurst Road and Golf Road generate grease and heavy restroom use. Commercial kitchens should have interceptors pumped on schedule and lines jetted regularly. Homes on streets near the major commercial corridors can see local sewers fill quickly during intense storms, as large paved areas shed water fast, so basement protection is a sensible investment for those blocks as well.
Nearby Crews
Crews working in Mount Prospect also cover Arlington Heights, Des Plaines and Prospect Heights, so response times across the area are generally reasonable. Share your nearest cross streets when you call.
Kitchen Care
Collect cooking grease in a can and throw it away rather than washing it down the sink.
Frequently Asked Questions
Is Mount Prospect on cast-iron or PVC piping?
Mostly PVC and clay from its postwar building boom - cast-iron is less common here than in Chicago's pre-war neighborhoods.
Can a 1950s subdivision still have root intrusion?
Yes - seven-plus decades is long enough for mature parkway trees to send roots into joint gaps in the original clay laterals.
Why do ranch homes get grease buildup in the kitchen line?
Single-story layouts often run the kitchen line on a long, low-slope path, which grease narrows over time more easily than a shorter run.

Yes, most homes here include a basement with a floor drain as the typical lowest fixture.
