Municipal Code Reference

Title VIII, Chapter 2, Article 13 of the City's Municipal Code provides that the user shall be responsible for clearing all stoppages and maintaining flow in the side sewer (consisting of the House Lateral and the House Sewer), in accordance with the following provisions:

  1. Stoppages or other maintenance and repairs required in the House Sewer shall be the responsibility of the User;
  2. The User shall be responsible for cleaning stoppages in the entire length of the House Lateral. If the stoppage cannot be removed by the User or plumber hired by the User, by rodding or other routine cleaning methods, the City will attempt to clear the stoppage through the street cleanout, (also known as property line cleanout) if one exists. If a street cleanout does not exist, the User shall be responsible for installing one. If the stoppage is found to be caused by grease, rags, or other foreign matter contributed by the User, or if in fact it is found that no stoppage exists, the User shall pay the City costs incurred. If more than one User is served by a single side sewer, the cost will be divided equally among the Users. If the stoppage is found to be caused by a broken pipe or other structural failure (of the House Lateral), necessary repairs will be made by the City at no charge to the User.
