The City of Smithville will soon undertake a $700,000 project to rehabilitate deteriorating sewer lines and manholes in certain parts of town including Earl Avenue, West Main Street, and Carter Street.
During Monday night’s regular monthly meeting, the aldermen voted to enter into a contract with the J.R. Wauford & Company Consulting Engineers to provide services related to the project.
The city’s share of American Rescue Plan Act (ARP) and Tennessee Department of Environment and Conservation (TDEC) grant funds will be used to cover costs of the rehab effort.

Daniel Tribble, Manager of Field Services for the J.R. Wauford Company who addressed the mayor and aldermen Monday night, said the project will be done in phases.
“We have been requested to review sewer lines that have been identified by your city personnel that are subject to what is believed to be inflow. Inflow is simply when water that is collected in streets and roadways or flowing in ditches and creeks enters your sewer lines, which in turn increases the sewer that you have to treat at your wastewater plant. A lot of times the vitrified clay pipe (VCP) like any utility has a certain life span and over years it simply deteriorates. The reports we have received are that in this case gravels, dirt, and other material that is not sewer has been found in these locations where the sewer line is believed to be failing or collapsing which allows the debris and inflow into your sewer lines. More than likely these lines would be replaced with PVC pipe which is the standard 8-inch PVC that we call SDR-26 sewer line pipe,” said Tribble.
“Due to the estimated cost of this job and the available funds we (J.R. Wauford Company) have proposed a phased approach to complete rehabilitation of the subject lines. Phase one of this project includes the open cut sewer replacement of approximately 2,700 feet of sewer line along Earl Avenue, West Main Street, and Carter Street. The second part of phase one of this job is the CCTV or closed-circuit television inspection of approximately 7,400 feet of sewer lines mostly in cross country areas that flow along creeks and not in roadways. Our plan is to review the CCTV footage and make a recommendation to the city as to the appropriate rehabilitation methods for these areas,” Tribble continued.
“The estimated cost of phase one of the project is $703,000. We need an executed contract between the City of Smithville and J.R. Wauford & Company in order for us to mobilize our survey crew and begin design work to get this project bid,” added Tribble.
The aldermen gave approval to proceed with the bid process.
