Kansas City Water and Sewer Rates: FY2027 Costs Keep Pressure on Commercial Accounts
KC Water FY2027 rates took effect May 1, 2026 after ordinances adjusting water and sewer charges. The commercial issue is high wastewater cost plus meter-size exposure.
Key Takeaway
KC Water says new rates take effect at the beginning of Kansas City fiscal years on May 1. The FY2027 rate book lists general meter monthly service charges by meter size, ordinary water commodity charges per CCF, and sanitary sewer volume charges of $12.90/CCF. For commercial properties, the biggest planning issue is the combined effect of meter-size fixed charges, water usage, and high wastewater volume charges.

What changed
Kansas City passed 2026 ordinances adjusting both water and sewer service charges. KC Water points customers to its FY2027 rate book for rates effective with billings on and after May 1, 2026.
The commercial signal is not only the water commodity rate. The rate book shows meter-size service charges, tiered commodity charges, and a sanitary sewer volume charge that can dominate the bill for accounts with high indoor use.
Commercial impact model
WaterForge models a 6% blended utility-cost scenario on a 300 kGal/month Kansas City commercial account as an added $171/month, or $2,052/year. That is a budget scenario, not a substitute for the account-specific rate book calculation.
A more precise model should convert monthly gallons to CCF, apply the general water commodity tiers, add the meter service charge, then apply sanitary sewer service and volume charges.
What operators should do
Start with the meter size. Large service connections carry materially higher fixed monthly charges, and they can hide in the bill while teams focus only on gallons.
Then model wastewater separately. If the property uses water indoors, every avoided gallon may reduce sewer exposure as well as water exposure. That is where Smart Valve can have a stronger combined-bill ROI than a water-only calculation suggests.
