The Chicago Department of Water Management (CDWM), Ancillary Sewer Program (North) includes various short-term assignments addressing intense aspects of individual projects that the City of Chicago crews are not equipped to perform. Projects are mainly contained in residential neighborhoods and included the construction of repairs of sewer mains, water main replacement, combined sewer replacement, repairs to both residential and commercial service connections. Projects also included pavement restoration, resurfacing, curb and gutter replacement, ADA-compliant sidewalk replacement, and site restoration.

Cotter provided construction inspection services for the program and directly coordinated with local businesses, schools, and residents within the project area boundaries to minimize inconvenience. This included investigating and coordinating residents’ and businesses’ concerns with the contractor’s work schedule.
