Don’t Connect Roof or Yard Drains to the Sewer System

During heavy rains, diverting runoff into the sewer system can dramatically increase the volume of water going to the treatment plant. Piping runoff water into the sewer system, either from house gutters or a sump pump, is in violation of District, local, and federal regulations. Any illegal drain must be disconnected from the sanitary sewer system and re-routed to the appropriate storm drainage system.
