Silver Spring WWTP Upgrade to Chesapeake Bay Standards
In response to Pennsylvania’s Chesapeake Bay Strategy, an initiative dedicated to water quality improvement, Pennoni designed and permitted the expansion and upgrade of the Silver Spring WWTP. Pennoni prepared a Conceptual Planning Study for the upgrade of the 0.6 MGD WWTP to 1.2 MGD. The selected alternative, a modified Sequencing Batch Reactor (SBR) with effluent filtration system, was designed and permitted by Pennoni. Pennoni also assisted the Authority in bidding the work and provided construction management and inspection. The total construction cost, which was covered under three separate construction contracts, was $8.9 million and was completed over 18 months.
