Preston WWTP(Waste Water Treatment Plant) Improvements

The Project consists of construction improvements at the City of Preston's existing wastewater treatment plant. The City intends to upgrade the WWTP with a new headworks, influent lift station, equalization storage, oxidation ditches, secondary clarifiers, tertiary membrane filtration, ultraviolet (UV) disinfection, and biosolids dewatering. Collection system improvements are also planned in selected portions of the City. Work includes demolition, as well as construction, of concrete and masonry wall buildings, piping, electrical systems, HVAC, plumbing, site work, miscellaneous appurtenant work, and installation of mechanical equipment. Mechanical equipment to be installed includes pumps, screens, aerators, clarifier mechanisms, preselected membranes, UV system, dewatering equipment, and other miscellaneous wastewater treatment equipment.
