Treatment Plant Upgrade

Larson Design Group (LDG) provided final design for an Act 537 wastewater treatment plant (WWTP) upgrade for the Porter-Tower Joint Municipal Authority’s (PTJMA) in Schuylkill County, Pennsylvania. The upgrade was intended to address a dry weather hydraulic overload and meet the Chesapeake Bay Tributary Strategy requirements stipulated by Act 537 for total nitrogen and total phosphorus. LDG services included grant application assistance, survey, wetland delineation, hydrologic/hydraulic analysis, site design, and structural engineering. The project involved replacing the existing extended aeration facility with a Fluidyne ISAM Sequencing Batch Reactor (SBR); the conversion of the existing WWTP to wet weather flow management facilities; construction of a new process building housing the new headworks facilities; new sludge drying beds with a covered roof; a new garage; and the conversion of the existing control building to an operations building.
