Philadelphia to receive $100M for wastewater treatment plant
Pennsylvania – More than $100 million in financial assistance from the Pennsylvania Infrastructure Investment Authority (PENNVEST) will contribute to the city of Philadelphia’s construction of a new 300-million-gallons-per-day (MGD) wastewater treatment facility.
Northeast Water Pollution Control Plant
The planned project at the Northeast Water Pollution Control Plant includes a diversion structure to reroute wastewater flow from existing 66-inch and 78-inch sewer interceptors, new screening and grit removal systems, and a tie-in conduit to connect to existing primary sedimentation tanks.
Screening facilities will be housed in a new 18,000-square-foot building and include two 72-inch magnetic flow meters, and six mechanically cleaned bar screens and associated screening conveyance, and collection systems. The grit facilities include six 26-foot diameter hydraulically induced vortex grit tanks surrounding an 8,000-square-foot pipe gallery which includes two grit pumps and associated piping for each tank.
A new two-stage odor control system will include two trains each consisting of a bio-trickling scrubber followed by carbon absorber to treat odorous compounds associated with the new facilities. A gas main and electrical infrastructure will be relocated to accommodate the new facilities.
This project will help the city meet regulatory requirements under the Federal Clean Water Act and the Pennsylvania Clean Streams Law.
