Live Data

Water quality changes rapidly in an urban environment. Monitoring technology helps us make better decisions and communicate with the public in a timely fashion.


The purpose of the CSOcast notification system is to alert the public of possible Combined Sewer Overflows from Philadelphia’s combined sewer system outfalls.

Philly RiverCast

The Philly RiverCast is a forecast of water quality that predicts potential levels of pathogens in the Schuylkill River between Flat Rock Dam and Fairmount Dam (i.e., between Manayunk and Boathouse Row).

PWD/USGS Cooperative Water Resources Monitoring Program

View detailed water quality information about Philadelphia's streams in the PWD/USGS Cooperative Program. This monitoring network is equipped with both water-quantity (water discharge and stage) and water-quality (pH, specific conductance, dissolved oxygen (DO), temperature, and turbidity) measurement equipment that reports data in near real time (within hours).
