Long Term Control Plan

Like other cities across the country, Indianapolis negotiated a Combined Sewer Overflow Consent Decree and Long Term Control Plan (LTCP) to reduce sewer overflows into local waterways. In 2010, Mayor Greg Ballard and administration officials were able to announce plans to save Indianapolis residents $740 million and provide cleaner waterways faster than originally planned. In addition to the savings, the improvements will divert ahead of schedule 3.5 billion gallons of sewage from polluting local waterways.

What is a Combined Sewer Overflow Consent Decree?

The Adobe PDF Consent Decree is an agreement outlining a 20-year plan to curb the overflow of raw sewage from combined sewers into waterways. The Consent Decree requires capture and treatment of 97 percent of the sewage overflows in the Fall Creek watershed and 95 percent in the White River watershed. By 2025, overflows will only be allowed to occur during two storms per year on Fall Creek and four storms per year on White River and other waterways.

In addition to its environmental and economic impact, the plan will help improve neighborhoods through design and construction of co-functional buildings and improvements at sites around the city. The plan has earned recognition from the U.S. Environmental Protection Agency (EPA) and other national organizations.
