To maintain our sewers and treatment plants and to comply with our Consent Decree, MSD needs to plan, design, and construct a variety of sewer infrastructure and CSO-related stormwater management projects. Our projects are divided into two main categories: Asset Management and Wet Weather. Asset management projects are projects to upgrade or replace existing infrastructure that is aging or deterorating. Wet weather projects are projects to reduce or eliminate sewer overflows per our Consent Decree. Please see the links below for more information. For questions about any MSD project, please contact Project Customer Service at (513) 557-3594 or
