SEWAGE: A combination of human excrement and wastewater that causes bacterial, sediment, and thermal pollution. Sewage most often enters our waterways through Combined Sewer Overflows (CSOs), Sanitary Sewer Overflows (SSOs), failing septic systems, and wastewater treatment plants illegally discharging. 

POSITION: Tragically, in the 21st century, we still have instances of raw sewage entering our waterways. The release of sewage through aging urban sewer systems is a main reason areas of the Potomac River are closed to swimming. Upgrading our infrastructure (i.e sewage tunnels and treatment facilities) and creating and upholding adequate regulations can help to resolve this major form of pollution.

OBJECTIVE: Work to eliminate examples or raw sewage discharge by pushing municipalities to improve infrastructure and to comply with the Clean Water Act. Identify and take legal action against wastewater treatment plants and cities that discharge sewage illegally.

Steps to Solutions:

  • Appeal inadequete stormwater permits.
  • Advocate for infrastructural improvement plans to resolve major stormwater issues, such as the full implementation of DC's Long Term Control Plan.
  • Work with companies and government to fix failing commercial septic systems.
  • Take legal action when necessary to resolve illegal raw sewage discharges.
