KCK is spending $16 million to keep sewage out of local creeks. What to know

Water from the Unified Government’s combined system flows into Jersey Creek through an area outfall on the afternoon of June 30, 2025. Outfalls deposit storm or sewer water from area pipes into local rivers and streams.

The Unified Government of Wyandotte County and Kansas City, Kansas, plans to begin a major sewer and stormwater separation project this summer in northeast KCK. The roughly $16 million effort aims to reduce incidents where heavy rain causes raw sewage — including fecal matter — to overflow into local creeks and streams.

FULL STORY: Summer rains flood KCK creeks with human waste. New project could help stop that

Here are key takeaways:

What’s being built: About 10,000 feet of stormwater lines and 900 feet of new sewer lines will be installed between 18th Street, Quindaro Boulevard, 12th Street and Parallel Parkway. Construction runs through summer 2028.

The problem: Much of eastern Wyandotte County uses a combined sewer system where stormwater and wastewater lines share pipes. During heavy rain, sewage can overflow into waterways, exposing people to toxic chemicals and harmful bacteria.

The bigger picture: The project is part of an EPA-mandated agreement requiring Wyandotte County to fully separate its sewer lines countywide — an estimated $1 billion effort — by 2044.

Who’s paying: Residents are funding the work through annual sewer rate increases scheduled through 2044, ranging from 2.5% to 5% depending on the year.

What to expect: Temporary road closures will affect the northeast KCK area over the next couple of years. Public information sessions are being held from 5 p.m. to 7 p.m. at the Mt. Carmel Redevelopment Corporation, 1130 Troup Ave., KCK.
