Pennsylvania Collection Systems: Class E Satellite Certification
Pennsylvania's Class E collection certification covers satellite collection systems with a pump station — a designation distinct from the flow-based wastewater treatment classes A-D, reflecting that collection-system operation (moving wastewater to a treatment plant) is a different skill set from treating it.
Inflow and Infiltration (I&I): The Core Challenge
Pennsylvania's older cities — particularly Pittsburgh (within the ALCOSAN service area) and Philadelphia — rely on aging clay and brick sewer infrastructure that allows stormwater and groundwater to enter the collection system. During heavy precipitation, this excess flow contributes directly to combined sewer overflows (CSOs), and increasing storm intensity is making I&I management an even higher priority for collection system operators statewide.
