HARRISBURG – Quandel Construction Group recently completed the upgrades to this wastewater treatment facility, which included an entirely new treatment process — two new sequencing batch reactor systems including mixers, decanters, pumps, diffusers, controls, instrumentation, post equalization tanks and aerobic digester tanks. A new Vortex Grit Removal System was added as well as a new Chemical Building. The existing chlorine contact tank was renovated, and three new sludge drying beds were constructed.
Quandel was responsible for coordinating the Electrical Contractor and the HVAC/Plumbing Contractor, in addition to all of its own subcontractors and in-house workforce.
Our largest challenge on this project was that the existing treatment system had to remain in operation continuously throughout construction.
