It is the responsibility of the property owner to call a plumber or sewer/drain cleaning service to correct the problem. The property owner is responsible for maintaining adequate flow to and through the sewer lateral from the property structure and into the sewer main. If your plumber or sewer/drain cleaning service believes the blockage is in the sewer main, the City will respond as quickly as possible and keep you informed of the progress.
Your plumber or sewer/drain cleaning service can contact the City at 605-642-1325 or after hours at 605-642-1300.
