Challenge: We were retained by the Pine Creek Municipal Authority (PCMA) to complete all phases of its Wastewater Treatment Plant (WWTP) upgrade.

 

Solution: The design criteria for the upgrade included an increase in the average daily design flow from 1.3 MGD to 1.6 MGD, the removal of both nitrogen and phosphorous for compliance with the Chesapeake Bay Initiative, and UV disinfection. The treatment processes included in the upgrade are a mechanically-cleaned screen; aerated grit removal; Fluidyne ISAMTM Sequencing Batch Reactor (SBR) consisting of a constant level anaerobic influent conditioning basin, a surge basin
(influent equalization basin), and SBR; post-equalization; cloth media filter; and UV disinfection. Other facilities incorporated in the upgrade are sludge conditioning, a belt filter press, and a seepage receiving station.

 

Outcome: Following construction, we helped PCMA obtain approvals from the both the Susquehanna River Basin and the PA DEP for the sale of treated effluent for natural gas well hydraulic fracturing. We designed the conversion of the original activated sludge treatment tanks to a treated effluent storage and tank truck loading facility.
