✎ Updated 20 Aug 2026 Publication date recorded for 6 sources. What changed →

In May 2010 the United States sued Kansas City over an annual discharge of approximately 6.5 billion gallons of untreated sewage into waters of the United States, and the settlement — a federal consent decree plus a $600,000 civil penalty — committed the city to a rebuild originally estimated to exceed $2.5 billion over 25 years and now planned as a 25-year, $4.5 billion – $5 billion program. The instrumentation came with the obligation: about 300 sensors deployed throughout Kansas City's 318 square miles measure water depth and flow in the sewer systems, built with the Indiana firm EmNet, and the utility says the readings feed a decision support system used to operate the gates that hold stormwater back during a storm. A third amended consent decree extended the final compliance date from 2035 to 2040.

FundingWastewater ratepayers under a federal consent decree; the city intends to raise rates 6 percent or less annually

📊 Impact

KC Water reports that capture of combined sewer overflows has risen from 45% to 68.5%, exceeding the 2024 milestone of 66%, against a decree requirement of 77% by 2035 and a final target of 85% by 2040. Nothing in the programme is independently evaluated: the figures are the utility's own reporting, which is what the decree obliges it to produce.

🎓 Lesson

The sensors never had to win a budget argument. A federal court set the number the city must report, and measurement is how compliance is proved — which is why the most thoroughly instrumented system in Kansas City is the one nobody chose to instrument.

What the mapping says
A city official describes using the sensor data through machine intelligence in a decision support system that operates the gates in the collection system. This is the operator's own description; no source states that the gates move without a human decision, so the entry does not claim automatic actuation.
