City's Infrastructure

Combined sewer overflow events (CSOs) occur during heavy precipitation and can overwhelm sewer systems. During this event...

• untreated sewage, rain water & grey water are released into a body of water

• untreated sewage, groundwater & greenwater are released into a body of water

• just untreated rain water and runoff are released into a body of water

• just treated sewage is released into a body of water

What is a benefit of a sanitary sewer system?

• sewage is always sent to a waste water treatment plant no matter the weather

• rainwater and runoff is always returned directly back to a freshwater source

• these sewer systems cost more money to maintain two sets of pipes

What is a pitfall (negative) to having sanitary sewer systems? (Select all that apply)

• this system separates sewage from storm water

• rainwater and runoff goes untreated before it enters a body of water

• these sewer systems cost more money to maintain two sets of pipes

How can rain gardens and green infrastructure benefit communities with Combined Sewer systems?

• This will reduce the amount of water the sewers receives during large rain events and reduce CSO events

• This will increase the size of the pipes in a combined sewer system

• This will increase the amount of water that enters our sewer system
