safety; affects how you and your neighbors feel• Someone’s been writing things on the
bathroom wall. How can we stop this?– Affects how your school looks, how you feel– Costs money to fix

Problem: Combined Sewers
www.phillyriverinfo.org
Problem: Combined Sewers
• US EPA estimates 6 billion gallons of raw sewage are discharged into Pittsburgh waterways (2004).
• Combined Sewer Overflow (CSO) warnings 70 days a year in Pittsburgh where contact with the water in not recommended (2009).
• A CMU study found that only 32% of Allegheny County streams meet PA’s safety standards for fecal coliform bacteria (2005).
• Cost to fix could be $1 to $50 BILLION.
Problem and Potential Solutions
• Our sewers are combined and overflow often during rain events.
• We pour “clean” rainwater directly into our sewer systems and it causes “dirty” sewage to overflow, untreated into our lakes.
• We use a lot of water (even when it rains) and our system is at full capacity so it overflows often.
Stakeholders
• Citizens– People who work/live near the water– People who live in Pittsburgh– People who recreate on the water (kayak, boat)
• Politicians / City Officials• Water Treatment Facility (& Institutions who use water)• Wildlife (Fish!)• Regulating Agencies (US Environmental Protection
Agency – US EPA)

• Meet with your fellow stakeholders• 5 minutes = Discuss what you (in your group) want to
do about combined sewers• Town Hall Meeting between all stakeholders
Town Hall Meeting
What should we do about combined sewers?
What CAN we do about Combined Sewers?
• City planning: each new construction must have combined sewers
• Alcosan signed agreement with Federal and State EPA to assemble a plan to address CSO by 2012 and implement it by 2026.
• When we DO replace pipes, we should separate storm water and sewage
• Permeable pavement and green roofs• Rain Barrels
