City Sanitary & Stormwater Sewers

The Public Works Department provides for the preventative maintenance, annual cleaning, and inspection of the city’s sanitary and stormwater / drainage systems in compliance with National Pollutant Discharge Elimination System (NPDES) and Community Rating Service (CRS) programs. Public Works maintains these systems to ensure their efficient operation, maximize flow capacity and reduce the possibility of sewage back-up in residences.
