Kansas Utility Connection Costs (2026): Tap Fees by City
In Kansas’s two largest cities, a new single-family home’s official water and sewer connection charges run from $4,795 in Wichita to $11,955–$17,295 in Overland Park, depending on meter size. Overland Park’s smallest published total, on a 5/8-inch meter, is roughly 2.5 times Wichita’s flat charge. That gap isn’t a sign Overland Park’s utilities cost more to run — it’s a different pricing structure. Wichita’s Public Works & Utilities department bills one flat connection-and-equity schedule regardless of a meter’s rated flow. Overland Park is served by two separate agencies, and WaterOne, its water utility, prices its System Development Charge on an exact formula: $290 for every gallon-per-minute of the assigned meter’s capacity. Our database covers these two Kansas cities so far. Other Kansas utilities are not yet collected, and we say so rather than guess.
Official fees in Kansas
The table below lists every verified Kansas fee row in our database, with utility, meter size and a link to the source document. The two cities structure their charges completely differently. Wichita charges a flat water connection fee plus a water plant equity fee and a sewer equity fee, sized only by whether the service is 1-inch or 2-inch — nothing scales with a meter’s actual flow rating. Overland Park’s water utility, WaterOne (Johnson County Water District No. 1), prices its System Development Charge at a clean $290 per gallon-per-minute of the assigned meter’s AWWA-rated capacity, and Johnson County Wastewater keys its sewer connection fee to that same water meter size.

| Situation | Wichita | Overland Park | Difference |
|---|---|---|---|
| New home, smallest meter each city offers | $4,795 (1-inch — no smaller service is listed) | $11,955 (5/8-inch) | $7,160 |
| New home, 1-inch meter | $4,795 (1-inch — same schedule) | $28,125 (1-inch) | $23,330 |
How the rows are built. Wichita: $1,812 water connection fee + $1,520 water plant equity fee + $1,350 sewer equity fee + $60 sewer permit + $53 account origination fee = $4,795, a flat charge under Code Sections 17.12.080 and 16.04.055 that doesn’t change once a lot has 1-inch service — Wichita’s price list has no 5/8-inch or 3/4-inch line at all. Overland Park: WaterOne’s $1,085 connection charge + $5,800 System Development Charge, plus Johnson County Wastewater’s $220 sewer permit + $4,850 sewer connection fee = $11,955 on the smallest available 5/8-inch meter. Step up to 3/4-inch and the same formula gives $1,095 + $8,700 + $220 + $7,280 = $17,295; at 1-inch it’s $1,275 + $14,500 + $220 + $12,130 = $28,125.
Split the totals apart and the source of the gap is clear. Overland Park’s WaterOne System Development Charge is built on an exact per-gallon-per-minute formula: $5,800 ÷ 20 gpm (the 5/8-inch meter’s AWWA rating) = $290, and the ratio holds at every size — 30 gpm (3/4-inch) × $290 = $8,700, and 50 gpm (1-inch) × $290 = $14,500. Johnson County Wastewater’s sewer connection fee is keyed to that same meter size, so a bigger WaterOne meter raises both agencies’ bills at once. Wichita has nothing comparable: its water plant equity and sewer equity fees are flat amounts tied only to the 1-inch/2-inch split in the ordinance, not to how many gallons per minute the meter is rated to pass. That’s why the two cities’ totals aren’t just different numbers — they come from two different theories of how to charge for capacity. Wichita treats it as a one-time flat buy-in; Overland Park meters it to the size of the pipe a home is given, and WaterOne — not the homeowner — picks that size.

What decides your number
- Which city and which agencies serve the lot. Wichita’s Public Works & Utilities department bills water and sewer together and performs the tap itself. Overland Park splits the same job across WaterOne (water) and Johnson County Wastewater (sewer), and each bills separately.
- Meter size, in Overland Park especially. WaterOne decides the meter size from the plans you submit, and that single decision drives both the water System Development Charge and the Johnson County Wastewater sewer connection fee — a jump from 5/8-inch to 3/4-inch adds $5,340 across the two agencies. Wichita only distinguishes 1-inch from 2-inch service.
- Your lot’s assessment history, in Wichita. If the parcel never paid into the benefit district that built the water or sewer lines in front of it, Wichita adds front-foot and square-foot “in lieu of assessment” fees that can more than double the $4,795 total.
- Timing. Wichita’s current water connection and plant equity fees took effect July 1, 2025. WaterOne’s figures come from a late-2025 capture of its fee page and could not be confirmed current as of this review; Johnson County Wastewater’s schedule dates to a March 2026 code edition. Call the utility before you budget either city’s total.
Kansas utility connection cost FAQ
How much do water and sewer connection fees cost in Kansas?
For a new single-family home, published city charges are $4,795 in Wichita on a 1-inch service. In Overland Park, published WaterOne and Johnson County Wastewater charges run from $11,955 on a 5/8-inch meter to $17,295 on a 3/4-inch meter, and $28,125 on a 1-inch meter.
Why is Overland Park so much more expensive than Wichita?
The two cities price capacity differently, not just at a different rate. Wichita charges a flat water plant equity fee and sewer equity fee that don’t scale with a meter’s flow rating. Overland Park’s WaterOne prices its System Development Charge at $290 per gallon-per-minute of the assigned meter’s capacity, and Johnson County Wastewater’s sewer connection fee scales with that same meter size — so a bigger meter raises both agencies’ bills together.
What is WaterOne’s System Development Charge formula?
It works out to an exact $290 per gallon-per-minute of the meter’s AWWA-rated capacity: $5,800 for a 5/8-inch meter (20 gpm), $8,700 for 3/4-inch (30 gpm) and $14,500 for 1-inch (50 gpm) — the same $290-per-gpm ratio holds at every size WaterOne publishes.
Does meter size change the fee the same way in both cities?
No. Overland Park’s total scales continuously with meter size because both WaterOne and Johnson County Wastewater key their charges to it. Wichita’s schedule only distinguishes a 1-inch service from a 2-inch service; within the 1-inch tier the $4,795 total doesn’t change with the meter’s rated flow.
