Homeowners in a north Naperville neighborhood are in line for more protection against a repeat of the sewage backups many of them experienced in last April’s floods.
The City Council will vote Tuesday on granting up to $537,778 to upgrade about 175 aging manholes partly blamed for the problem in the Cress Creek subdivision, north of Ogden and Fifth avenues.
Staff are recommending that the work go to Red Horse, Inc. The contractor, based in Stoughton, Wisc., was one of two bidders submitting proposals after two dozen were given the manhole rehabilitation plans, and has done work for the city before.
“Staff has worked with Red Horse successfully in the past and they are the low bidder without exception,” Mike Bevis, the city’s chief procurement officer, said in a council memo.
The work will be part of a $4.6 million allotment the council has earmarked for assorted sanitary sewer work. The 2013-14 municipal budget initially included $2.2 million for the purpose citywide, but the council added another $2.4 million in June to address Cress Creek, where residents reported extensive sewage backup after heavy rain drenched the city in mid-April.
Council members in November gave the go-ahead to replace the lining in the neighborhood’s sewer pipe network, at a cost of $1.84 million.
The manhole fix, which has been done in the city before, involves the use of layered polyurethane coatings that lend structural strength and add an impermeable lining to prevent groundwater infiltration and protect the inner walls from corrosive sewer gasses that can damage the concrete surface.
