WASHINGTON – The city of Kansas City, Mo., has agreed to make extensive improvements to its sewer systems, at a cost estimated to exceed $2.5 billion over 25 years, to eliminate unauthorized overflows of untreated raw sewage and to reduce pollution levels in urban storm water, the Justice Department and U.S. Environmental Protection Agency (EPA) announced today. The settlement, lodged today in federal court in Kansas City, requires the city to implement the overflow control plan, which is the result of more than four years of public input. The plan is designed to yield significant long-term benefits to public health and the environment, and provide a model for the incorporation of green infrastructure and technology toward solving overflow issues.
