GREEN CITY,CLEAN WATERS The City of Philadelphia’s Program for Combined Sewer Overflow Control
$2.4 Billion Investment over the next 25 years
Green Stormwater Infrastructure
Traditional Infrastructure
Adaptive Management
$1.67 Billion
$354 million
$420 Million
PWD’s initial plan for performing monitoring of natural and engineered systems associated with our Green City, Clean Waters program and addresses the monitoring and assessment of surface waters, groundwater, rainfall, CSO discharges, sewer flows, and green infrastructure performance.
Green City, Clean Waters Comprehensive Monitoring Plan
Consent Order & Agreement: Deliverable III Submitted to: PA DEP December 1, 2012
Why Monitor Green Infrastructure 1. Evaluate Green Infrastructure Performance
2. Inform Future Designs
3. Inform Maintenance
4. Compliance
How are Monitoring Sites & Activities Selected?
Coordination with Pilot Program
Identifies •Stormwater Management Practice (SMP) type •Variables (or Conditions) in projects •Questions about the projects and how variables impact SMP effectiveness

Low Cost GSI Monitoring Sensors
• What if we have to monitor hundreds of GSI sites?
• Budget and manpower constraints
• This is the 21st century
• Applications for both green and gray infrastructure
• Potential use in STEM education

Ping Floyd – The Well
Ping Floyd v2.0, a.k.a. Pong Floyd • Infrared distance
sensor • Range up to 5 meters • Compatible with slotted
observation well • Detects ping pong balls
floating at the bottom of the well
• Logs water level data to SD memory card
