City Sanitary & Storm Water Sewers

The Public Works Department provides for the preventative maintenance, annual cleaning, and inspection of the city’s sanitary and storm water / 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.

Effective April 1, 2017, the City will no longer levy a special property tax assessment for the properties within Special Service Areas 1, 2, 3, and 4 for sanitary sewer service. These properties will receive a quarterly bill for sanitary service the same as the other customers from the former Old Town Sanitary District.
