In 2008, in order to increase the efficiency of its sewer system, South Bend began the installation of an array of intelligent sensors and valves allowing it to become the first city to migrate its sewer system management to the cloud.

This more efficient system has helped to save the city an estimated $100 million in new sewage pipes. Environmental initiatives In 2015, South Bend engaged in a partnership with the University of Notre Dame to revitalize the Bowman Creek ecosystem.
