A Program Of The

City Of Columbia

the-commitment-cycleThe City of Columbia is committed to a more efficient and reliable wastewater collection and treatment system for the long-term. 

Clean Water 2020 will:

  • Assess the wastewater system
  • Improve infrastructure
  • Reduce sanitary sewer overflows
  • Protect the health and safety of Columbia's citizens
  • Improve water quality

Reducing sanitary sewer overflows (SSOs) will improve water quality and allow the City to meet government guidelines. Upgrades to the system are already making a difference. SSO events have declined from over 400 in 2009 to 155 in July 2016. 

Clean Water 2020 will use a five phase project cycle that allows the program to follow the federal Consent Decree and meets its goal to reduce and end SSOs.
