According to Cassville Public Works Director David Brock, after years of preparation, a significant overhaul of Cassville's sanitary sewer system is expected to begin as early as next week.
The goal is to replace or rehabilitate old pipes and manholes that allow stormwater runoff into the system in the flood plain, where the groundwater tables are the highest, with approximately 80% of the upgrades being traditional open trench, and the remainder will use a trenchless restoration process using cured-in-place pipe and manhole relining.
The open trench construction will be very disruptive in the immediate area of working machinery and equipment. Much of the work will occur within the paved portion of city streets. Residents should expect partial and complete road closures and temporary prohibitions on on-street parking.
The trenchless rehabilitation will use existing manholes to access the sewer lines, and machinery and equipment used for this type of repair will often be within the street right of way. They may partially block one or both driving lanes.
Brock states that the contract documents call for the project to be substantially complete (fully functional and in operation) within 365 days, with any remaining cleanup/restoration and paperwork completed within another 60 days. He also advised that the project will likely extend beyond one calendar year as there are provisions to exclude days lost due to poor weather or ground conditions and other factors outside the contractor's control.
"The project has an expected price tag of $5 million and will be funded through a loan from the USDA (United States Department of Agriculture), Rural Development with an annual interest rate not to exceed 2.125%," says Brock. "The loan will be repaid with sewer user fees over 35 years. The City has made a number of small incremental increases in the sewer rates over the last several years and does not foresee a substantial rate change being needed to make the new debt service payments."
