From Passive to Dynamic Storage - Water Environment & Technology

During the past decade, the Philadelphia Water Department (PWD) has emerged as a leader in efforts to address combined sewer overflows (CSOs) by innovative means, particularly through green infrastructure. Rather than controlling overflows solely by storage tunnels and other traditional gray infrastructure, PWD adopted its nationally recognized Green City, Clean Waters program in 2011.
The groundbreaking effort promotes the widespread implementation of green infrastructure practices designed to capture and manage stormwater onsite, reducing the volume of runoff entering the city's combined sewers. In keeping with this cutting-edge approach to stormwater management, PWD recently implemented continuous monitoring and adaptive control (GMAC) technology on a project for the first time.
Retrofitting this retention basin with continuous monitoring and adaptive control technology brought the facility into compliance with Philadelphia's stormwater management standards. OptiRTC
Used to retrofit an underperforming retention pond, the technology enables remote monitoring and dynamic control of stormwater management facilities, improving performance cost effectively while providing real-time sensor data to facilitate analysis of system performance.
