Project Info

Title
Wastewater Treatment Plant Expansion and Upgrade Project
Description
The Project consists of upgrading the headworks facility by installing a chain and rake screen ahead of the two existing Archimedes screw pumps. A washer/compactor will also be installed to handle the screen debris, with the existing grinders acting as a redundant barrier. An alkalinity addition feed station will be installed at the headworks facility to allow for better water quality in the denitrification process. This process will consist of a series of probes in the existing oxidation ditch which will operate variable frequency drive aerators to accomplish this process. The sludge pumping facility improvements will replace the motor end of the current pump housing with new VFD controlled units. A sludge dewatering process will be accomplished by a screw-press unit that squeezes the water from the solids. A new administration building will allow for an expanded control center, lab space, and areas for staff. The existing administrating building will be converted to electrical and supervisory control and data acquisition system/programmable logic controller housing. Other site improvements include enhanced security fencing and covered beds for the sludge dewatering processes.
