Check to see if the drain problem you are having is isolated to one sink, bathtub or other single fixture. If so, the problem is in the drain line to that fixture and you are responsible for taking care of the problem. If the problem seems to be throughout the home, call Veolia first. We will check the main lines to see if there is a back up in the sewer main system. If the problem is in the City's sanitary sewer main line, Veolia will clear the stoppage as quickly as possible. There is no charge for this service. If there is no stoppage in the sewer main lines, we will notify you that the problem is in your sewer lateral and you can then call a plumber or other person capable of clearing your sanitary sewer lateral.
