The Venice Island Underground Storage Basin project is located between the Manayunk Canal and the Schuylkill River, between the Lock and Cotton Street bridges in the Manayunk neighborhood of Philadelphia. The purpose of the enclosed basin is to temporarily store diverted flow from the sanitary interceptor sewer during intense rain storms. The basin is capable of storing nearly four million gallons of water that is later pumped out and directed to a treatment plant.
Improvements include a 250-seat performing arts theater on top of the new basin, which will be the jewel of the island's new recreation center. It also houses a multi-purpose recreation building where community meetings and after-school events for children can be held. The area also houses athletic fields; a kid's spray pool; small stations that will educate visitors about rainwater recycling; an all-green pumping station; and a 25,000-square-foot park.
