As mandated by the Consent Decrees, MSD developed a $3.1 billion Wet Weather Improvement Plan (WWIP) to substantially reduce combined sewer overflows (CSOs) and eliminate sanitary sewer overflows (SSOs) and sewer backups into homes and businesses caused by MSD's sewer system. The plan was initially submitted to the Regulators in June 2006. Significant changes were made to the plan in 2008 and 2009, and it was ultimately approved by the Regulators in August 2010.
The WWIP was rebranded as Project Groundwork in 2009.
Highlights of the wet weather plan include:
