CROWN POINT | Work to replace faulty sections of sewer line and treat manhole covers will get under way as part of an ongoing, state-mandated overhaul of the city sewer system.
Contracts totaling about $1.1 million were awarded Wednesday by the Board of Public Works and Safety.
Up to 200 manhole covers will be sprayed with specialized plastic to keep out stormwater, under terms of a $515,170 contract awarded to Westchester, Ind.-based Culy Construction, City Engineer Tris Miles said.
The job involves lowering a worker into the sewer to spray on the coating. The Culy Construction bid was the lowest qualifying bid of six, Miles said.
Highland, Ind.-based Grimmer Construction was awarded a $580,084 contract for work to replace faulty sections of sewer line that were identified through smoke testing earlier in the project, Miles said.
The Grimmer Construction bid was the lowest qualifying bid of three, Miles said.
The completion of both projects should reduce the frequency and severity of stormwater infiltration into the sewer system, Miles said. Preparation work is expected to get under way this week.
The state in 2007 ordered the city to correct the overflow of stormwater into sanitary sewers after heavy rainfalls. A 2018 deadline was set.
The problems stemmed from combined sewer systems permitting both stormwater and sanitary flow in older parts of the city.
The city is working with the Indiana Department of Environmental Management on the project, with a total estimated cost of $36 million. Indianapolis-based Commonwealth Engineers is overseeing the work.
The project is funded from the low-interest, state revolving loan fund, repaid from city sewer utility revenue. Utility rates have not been increased to fund the project.
The city was able to secure low interest rates of up to 1.8 percent because of its record of complying with environmental standards, Mayor David Uran said.
