Project Summary
Timmons Group was a principal in this Design/Build project procured through the PPEA Guidelines for a new 1.25 MGD BNR wastewater treatment plant, which is expandable to 3.75 MGD treatment capacity. The plant design includes the following processes: step screen, grit collection and removal, 5-stage Bardenpho oxidation ditch, secondary clarification, RAS/WAS pumping station, rotating disc filtration, horizontal UV disinfection, post aeration polishing, aerobic digestion, and centrifuge sludge dewatering. The design process included equipment pre-selection, all engineering coinciding with construction activities, as well as all regulatory coordination and approval. The project design and construction takes into consideration the phasing of other PPEA associated projects including a new 1.8 MGD wet/dry pit pump station, as well as 11,000 L.F 24” gravity sewer, 9,000 L.F. 16” force main, which were all operational prior to completion of the new WWTP.
