CSO Projects
CSO Project Milestones
In July 2001, the EPA and state EPD approved the City’s plan to eliminate water quality violations from CSOs. The City’s approved plan was to construct a CSO tunnel and sewer separation of selected sewer areas. This would improve water quality in our local streams and creeks by reducing the number of CSOs.
