Exciting progress is underway at the Mallard Creek Water Reclamation Facility, one of Charlotte Water’s primary wastewater treatment plants. As part of a major expansion, several key milestones were recently celebrated, advancing both liquid and solids process improvements to serve the growing Charlotte area.
One of the most notable achievements involved a 900-cubic-yard concrete slab placement for a 15-million-gallon equalization tank. To maximize the efficiency, the first trucks rolled in at 2 a.m., eliminating site traffic congestion and optimizing pump truck access for the duration. Precon Corporation was crucial in the success of this operation and is now constructing the walls for two equalization tanks.
Adjacent to the equalization tanks, construction of the influent pump station included a 65-foot excavation through soil and rock, supported by a soil nail wall system. Using mass concrete, the structure was constructed and has been backfilled to grade. The team is currently completing masonry around the pump station’s electrical room, constructing the remaining elevated concrete slabs, and installing interior electrical and mechanical piping.
Significant upgrades are also in progress at the existing biosolids handling facility to incorporate a new thickening and dewatering polymer feed system. Once complete, these improvements will enhance reliability and efficiency in biosolids processing.
Additional construction activities include the installation of new yard piping, replacement of grit facility equipment, and the addition of chemical feed pumps at the Alkalinity Facility.
These efforts are all part of the broader expansion aimed at increasing the facility’s treatment capacity from 13.1 mgd to 16 mgd. Once completed, these Phase 1 improvements will help ensure Charlotte Water can meet growing demand while supporting ongoing development throughout the region.
