Basement Water Problems in Derby, KS
What starts on this page is a request for contact, and it goes no further. One independent contractor receives it, gets in touch its own way and, having seen the basement, lays out the options. Nobody can promise a basement will never take on water.
Founded on July 11, 1871 under another name, the town took the Derby name at its rail depot in 1880, incorporated in 1903 and made the name official in 1956. In 1869 the Garrett family had already built a sod house on a homestead that is now Garrett Park.
A 1950s Core and Newer Blocks
Derby's first wave of houses followed McConnell Air Force Base, founded between Wichita and Derby in 1952; the town grew from 432 people in 1950 to roughly 5,000 by 1956. About 15% of today's homes date from that decade and are now around 70 years old.
The rest is younger: Census survey data put the typical home at about 1991, with about 37% built since 2000. The 11,026 homes, about 72% detached, hold 26,606 residents in 10,447 households, and about 69% of households own, at a median value of $236,900.
Plenty of Kansas houses sit on slabs or crawlspaces; this page covers those with basements. A 1950s block wall can weep at its mortar joints, while a 2000s basement can leak where drain tile has silted up or backfill has sunk.
What Derby, KS Homeowners Ask For
Recent Downpours Around Derby, KS
The National Weather Service recorded 4.19 inches in 24 hours at Derby during the storms of June 20–21, 2026. Days later, on June 25–26, southern Sedgwick County sat in a band that took 4 to 7 inches, largely within two or three hours.
Rain that heavy overwhelms gutters and yard drainage together. Dense clay that drains slowly is common under south-central Kansas topsoil, so water can stay pressed to basement walls long after the clouds leave.
Derby, KS Sewer Lines and Permits
Derby runs its own wastewater system: a City plant designed for 2.5 million gallons a day, plus 127 miles of sanitary sewer pipe and 2,839 manholes. Report a backup at 316-788-0301 in business hours, or 316-788-1557 after hours, on weekends and on holidays, and as the City asks, reach the Wastewater Department before making any repairs.
The City cleans and repairs the mains, but the service line from the main to the house, wye included, is the property owner's. Any repair there, or a backwater valve on the owner's side if one suits the home, is a job for a licensed plumber pulling a permit.
Permits and contractor licenses come from Building Trades & Inspections (611 Mulberry Road, Suite 300; 316-788-6632, Option 2). Structural or excavation work may need a City permit; you and the contractor settle which apply first.

Derby, KS Questions, Answered
Who owns the sewer line between my Derby house and the main?
You do, according to the City: everything from the main to the home, wye included, while the City cleans and repairs the mains. Before anyone digs up or clears that line, contact the Wastewater Department, 316-788-0301, or 316-788-1557 outside business hours.
Water came up my floor drain. Is that a basement waterproofing job?
Probably not. Water rising from a floor drain usually signals a sewer problem, not seepage, and basement waterproofing won't solve it. Report it to Derby's Wastewater Department first; repairs on the service line belong to a licensed plumber with a permit.
Our basement dates from the 2000s. Why does it take on water?
Drain tile can clog or may never have reached a working sump, pumps wear out, and backfill can settle until the yard tilts toward the house. Heavy rain on slow-draining clay then keeps the walls wet, and the contractor can say which applies after a look.
How do I check a contractor's Derby license?
Ask the contractor for its City license number in writing and confirm it yourself with Building Trades & Inspections, 316-788-6632 (Option 2). This site names no contractor and checks no licenses, so that step stays with you, along with insurance certificates and references.
