College Station's City Council is set to decide Thursday, Oct. 22, whether to hire Cash Construction Company Inc. to replace the next stretch of the Northeast Sewer Trunk Line, a main sewer artery whose older sections date to 1973 and run along the eroding banks of Carters Creek.
The construction contract is $13,644,510. With a $1 million city contingency, the council would be approving up to $14,644,510. The item sits on the consent agenda, where several items are approved in one vote unless a council member asks to pull one out.
What the line does
According to the staff summary in the meeting packet, the trunk line carries wastewater from neighborhoods west of State Highway 6, including Northgate, Hensel Park, Century Square and Chimney Hills, and from areas east of the highway between FM 60 and the Carters Creek Wastewater Treatment Plant.
Large parts of the current pipe went into the ground in 1973, and staff wrote that the wandering creek bank now endangers it. The city designed a multiphase project to install bigger pipe and shift the line farther from the creek.
According to the summary, the aim is to head off surcharge events and erosion-driven pipe failures, along with potential penalties from the Texas Commission on Environmental Quality.
Phase 3 scope
This phase would replace the line from south of Harvey Road (State Highway 30) to west of Highway 6. The packet lists more than 8,000 feet of new 30-inch and 36-inch sewer pipe, slip lining to rehabilitate about 1,000 feet of existing sewer, and 1,000 feet of new 42-inch pipe where the work ties into an earlier phase.
Staff said this phase must be finished before the city can build Phase 4, which serves the Northgate and Chimney Hill areas.
