TERRE HAUTE —
F. A. Whilhelm Construction Co. of Indianapolis has been awarded a $3.4 million contract to install floatable controls at Spruce Street as part of the city’s effort to separate storm water from sewage.
The contract was awarded Tuesday by the Terre Haute Board of Sanitary Commissioners.
Spruce Street marks the city’s northern-most overflow pipe that discharges storm water into the Wabash River. “As part of our long-term control plan, we are required to filter or screen any water that overflows into the river,” City Engineer Chuck Ennis said.
“So all the pop bottles and plastic top bottles, aluminum cans or trash from the road, whatever gets into the storm drains, is screened before it overflows out into the river.”
The screens are like large drums that rotates to allow water through; however, they catch debris with a brush and then redirect that debris back into the main sewer line, where it is sent to the city’s sewer headworks, which filters out the materials, Ennis said.
“We will do another floatable control structure at Idaho Street at the river,” the engineer said.
Whilhelm was the lowest of two bids. The top bid was $3.7 million. The city’s estimate for the project was about $4 million.
• In other business, Sixth Street at Maple Avenue and extending to Eighth Avenue will be closed on Aug. 12 and remain closed until Oct. 11. The closure is a continuation of a storm separation project toward the south.
• The board approved a change order to move the final completion date for the Hulman Lake Dam project to Dec. 27, from Sept. 30.
The project had been delayed after a complaint filed by Joseph A. Cloutier, sole member of C. Long LLC, contending the project could impact property along the lake. That complaint was dropped.
Still pending are other complaints filed by C. Long against the sanitary district concerning alleged property damage caused by the lake rising beyond its easement area.
Hulman Dam is to be raised approximately five feet to meet new state requirements for any dam whose breach would result in significant damage to homes or infrastructure. A 2011 study of the Hulman Dam by Banning Engineering, a Plainfield-based company, determined a breach of the dam would affect thousands of Terre Haute homes to the west of Hulman Lake.
