ELKHART, Ind. (AP) — A northern Indiana city is looking at an expansion of part of its sewer system that could cost millions of dollars in the coming years.

The Elkhart Truth reports that utility engineer Tory Irwin said a sanitary sewer line serving an area north of the Indiana toll road along Cassopolis Street is at capacity. The problem could clog up new development in the area.

A study presented to Elkhart’s Redevelopment Commission last month showed options starting on the low end at $3.8 million in capital costs and $4.8 million in a 5-to-10-year life cycle cost.

The study says the financial burden can be assumed by a combination of several parties, including residents and customers, public agencies and the sanitary sewer utility.
