Overland Park Water & Sewer Tap Fees (WaterOne + JCW, 2026)
Most of Overland Park gets its water from WaterOne, the trade name for Johnson County Water District No. 1, and its sewer service from Johnson County Wastewater (JCW), a county department. For a new single-family home, the published charges from the two agencies run from $11,955 with a 5/8-inch water meter to $17,295 with a 3/4-inch meter: a water connection charge, a water System Development Charge, a $220 sewer permit fee and a meter-sized sewer connection fee. The biggest thing to know before you budget: WaterOne, not the homeowner or builder, decides which meter size a house gets, and that one decision also sets the tier of the sewer connection fee, since JCW bases its charge on “the building’s domestic water meter size.”
Overland Park tap and connection charges at a glance
The table below lists every Overland Park row in our database with its source. WaterOne bills its connection charge and System Development Charge per new water service, sized to the meter it assigns; Johnson County Wastewater bills a flat permit fee plus a connection fee keyed to that same meter size. Rows marked as not typical cover a 1-inch meter for larger homes or one-time exceptions like a permit revision.

Worked example for a single-family home in Overland Park
WaterOne’s Charges & Fees schedule lists a New Water Service Connection Charge of $1,085 for the smallest residential option, a 5/8-inch meter on a 1-inch service line, and $1,095 for a 3/4-inch meter on the same line. On top of that, WaterOne charges a System Development Charge (SDC) that “compensates WaterOne for investments required in water supply, treatment, transmission and distribution facilities,” paid in addition to the connection charge: $5,800 for the 5/8-inch meter, $8,700 for the 3/4-inch meter. The SDC table follows a clean formula once you see it: $290 per gallon-per-minute (gpm) of the meter’s rated capacity, using the 5/8-inch meter’s 20 gpm AWWA rating as the base ($5,800 ÷ 20 = $290). A 3/4-inch meter’s 30 gpm rating gives 30 × $290 = $8,700, and a 1-inch meter’s 50 gpm rating gives $14,500 — the same ratio holds all the way up to WaterOne’s largest turbine meters.
Johnson County Wastewater’s residential permitting fee schedule charges a flat $220 Sewer Connection Permit Fee, which includes one inspection, plus a Sewer Connection Fee set by the same domestic water meter size: $4,850 for 5/8-inch, $7,280 for 3/4-inch, $12,130 for 1-inch. A teardown-and-rebuild project gets credit for the previous building’s meter size.
Published WaterOne and Johnson County Wastewater charges for one new single-family home, by the meter size WaterOne assigns.
| Meter size | Water connection charge | Water SDC | Sewer permit | Sewer connection fee | Total |
|---|---|---|---|---|---|
| 5/8 inch (smallest residential option) | $1,085.00 | $5,800.00 | $220.00 | $4,850.00 | $11,955.00 |
| 3/4 inch | $1,095.00 | $8,700.00 | $220.00 | $7,280.00 | $17,295.00 |
| 1 inch (larger homes) | $1,275.00 | $14,500.00 | $220.00 | $12,130.00 | $28,125.00 |
What is not included in Overland Park fees
WaterOne’s charge covers the tap at the main and materials for the meter and meter pit. JCW’s fees cover the sewer permit and inspection. Neither agency’s published fees include:
- Private water service line from the meter pit to the house. National estimate $30–$150 per foot, typically about $50, trenching included. See water service line cost.
- Building sewer line from the house to the JCW main, built by a private contractor (the permit application lists a separate interior and exterior plumber). National estimate $50–$250 per foot, typically about $100, trenching included. See sewer lateral cost.
- Street cuts and hard digging where the service crosses a paved street. National estimate $1,000–$10,000 per crossing. See utility trenching cost.
- City of Overland Park building and plumbing permits, separate from the JCW sewer permit, which JCW says is required before the City will issue a building permit.
- Electric service. We did not read a primary Evergy line-extension document for this batch; ask Evergy about your lot.
- A published account-opening or utility deposit fee. We did not find one posted on WaterOne’s site; ask when you apply for service.

When you pay Overland Park connection fees
WaterOne calculates the connection charge and SDC “at the time of permit processing,” once you submit plans meeting its installation, metering and cross-connection standards. Both charges are valid for 120 days from the date the permit is issued; if the tap isn’t made in that window, WaterOne can cancel, refund, or increase the cost of the permit.
Johnson County Wastewater requires a Sewer Connection Permit before the City will issue a building permit. Applications go through the MGO Connect portal and list the address, legal description, domestic water meter size, and contacts for the applicant, owner, builder, interior plumber and exterior plumber. Under the sanitary sewer use code (2026 Edition, Article 3, Part A, Section 4), the permit and connection fees are due “prior to commencement of construction,” and an unpaid fee becomes a lien on the property. The $220 permit fee includes one inspection; extra trips cost $38 each, and a $100 fee applies if a permit expires or the plans need revision.
Upcoming changes in Overland Park
- WaterOne’s 2025 rates may already be out of date. Every WaterOne figure here comes from an Internet Archive capture of its Charges & Fees page dated Dec 11, 2025 — the newest we could find — labeled “2025.” A Mar 1, 2025 capture shows identical numbers, but WaterOne’s calendar-year labeling implies an annual update, and we could not reach waterone.org from our research network on Sep 26, 2026 to check for a 2026 revision. Call WaterOne at 913-895-1800 before you budget.
- Sewer fees can change without notice. The sanitary sewer use code says permit and connection fees “will follow the latest fee schedule adopted by the BOCC” under Charter Resolution No. 29-92, and “are subject to change without notice.” The Board of County Commissioners approved the code’s 2026 Edition on March 26, 2026, and the fee page’s own metadata shows an update dated March 18, 2026 — both suggest the current sewer schedule has held since roughly then. It was still live on jocogov.org when we checked on Sep 26, 2026.
For comparison, Wichita’s published city charges for a new home total $4,795 on a 1-inch service — a single flat fee from one department that also performs the tap. Overland Park splits the cost across two agencies and scales it steeply with the meter size WaterOne assigns, so two otherwise-identical new houses in the same subdivision can land $5,340 apart depending on that one sizing decision.
Overland Park tap fee FAQ
How much does it cost to connect a new home to water and sewer in Overland Park?
For a new single-family home, published WaterOne and Johnson County Wastewater charges run from $11,955 with a 5/8-inch water meter to $17,295 with a 3/4-inch meter. That covers WaterOne’s New Water Service Connection Charge and System Development Charge, plus JCW’s $220 sewer permit fee and its meter-sized sewer connection fee. It does not include the private water line, building sewer, or building permits.
What size water meter will my new home need?
WaterOne decides, based on the plans and fixtures you submit — its fee page states plainly that “meter size and type is determined by WaterOne.” A 5/8-inch meter is the smallest residential option; each step up raises both the WaterOne charge and the JCW sewer connection fee, since JCW bases its fee on the same meter size.
What is WaterOne’s System Development Charge?
It is WaterOne’s growth-pays-for-growth charge, paid on top of the connection charge, to cover investment in water supply, treatment, transmission and distribution capacity. It works out to $290 per gallon-per-minute of the assigned meter’s rated capacity: $5,800 for 5/8-inch (20 gpm), $8,700 for 3/4-inch (30 gpm), $14,500 for 1-inch (50 gpm).
Does WaterOne or Johnson County Wastewater install the pipe to my house?
WaterOne’s charge covers the tap at the water main and materials for the meter and meter pit; from the meter to the house is the owner’s private line. On the sewer side, JCW permits and inspects the connection, but its application lists a separate interior and exterior plumber, meaning a private contractor builds the building sewer to the JCW main.
Can these fees change without notice?
Yes for the sewer side: the Johnson County Code of Regulations for Sanitary Sewer Use says connection and permit fees follow “the latest fee schedule adopted by the BOCC” and are “subject to change without notice.” WaterOne’s fee table is labeled by calendar year, implying an annual update; we could not confirm from our network whether a 2026 revision has already taken effect beyond the 2025 figures shown here.
