CHICKASHA — A section of sanitary sewer main in Chickasha that has been in poor condition for the last four years will be replaced under a $317,500 contract.
The Chickasha Municipal Authority awarded the job to Matthews Trenching Co. of Oklahoma City, the lowest of three bidders for the work.
The work will consist of installing 299 linear feet of 12-inch diameter PVC sewer main inside a 20-inch diameter steel casing under U.S. Highway 62 near 16th Street, two sanitary sewer manholes and a $35,000 sewer flow control mechanism. The existing line will be plugged and abandoned, a bid tabulation document indicates.
“This project is needed to remedy an ongoing situation in which the existing sanitary sewer main has failed,” and city staff has been “compelled to bypass pump for an extended length of time,” Public Works Director Jim Crosby informed the CMA. The faulty line attracted the attention of the state Department of Environmental Quality.
The city previously advertised the replacement project, but the bids were rejected and the job was bid again.
Although Matthews’ price was $62,175 higher than the engineer’s estimated project cost, “The need to complete this project is paramount to prevent potential discharge permit violations and to eliminate further wasteful labor and equipment costs associated with bypass pumping of this sanitary sewer main,” Crosby wrote.
Matthews Trenching “has successfully completed many projects of a similar nature in Oklahoma,” Crosby added.
