Federal officials have reached an agreement with Indianapolis that modifies the city's plans to reduce raw sewage overflows into several rivers and streams.
The Justice Department and Environmental Protection Agency announced the deal Monday.
The agreement modifies a 2006 consent decree. The new plan includes an accelerated construction schedule for the city's efforts to reduce sewage overflows from systems that carry both storm runoff and sanitary waste.
The new plan is expected to reduce overflows from about 7.8 billion gallons to about 414 million gallons per year.
The Justice Department says Indianapolis would save about $444 million of the original projected 20-year cost of $1.73 billion.
A federal judge must approve the agreement.
