Sanitary Sewer Cleaning

Done annually:  Summer through Fall 

The Department of Public Works will be cleaning (called “jetting”) our sanitary sewer system through manholes or other structures as part of necessary routine maintenance to keep our sanitary sewer system in proper working condition. 

BEFORE our sewer jetting crews arrive

  • Locate any sanitary manholes on your property and remove any obstructions including grass, mulch, yard decorations, etc. These structures must stay visible at all times for routine inspections and for emergencies. If our structures are covered or obstructed upon our arrival, our crews will have to uncover these structures and will not replace anything, including sod.
  • Keep the lid down on all of your toilets to minimize the water splashing out of your toilet. We remind you that the water that could splash out of your toilet during this routine maintenance is from your bowl.

DURING cleaning of sanitary sewer lines, air occasionally vents into a home through the sanitary sewer line.

  • Keep the lid down on all of your toilets to minimize the water splashing from your toilet because, in rare instances, water can splash out of the bowl or drain. We remind you that the water that could splash out of your toilet or drains during this routine maintenance is from your bowl or drain.
  • It is normal to hear gurgling or some sounds transmitted through your drain plumbing while we are jetting.
  • Sometimes during the sewer cleaning, the water in your toilet bowls and drains can be pulled out or emptied. If this occurs, you may smell sewer gas. Flush the toilets and run water in every sink and drain to refill the water traps to stop the smell.

AFTER the sewer cleaning is done

  • If you experience a smell coming from inside your sinks, toilets or drains, flush the toilets and run water in every sink and drain to refill the water traps to stop the smell.
  • Make note of the location of any sanitary manholes on your property and make sure that they remain free from obstructions including grass, mulch, yard decorations, etc. These structures must stay visible at all times for routine inspections and for emergencies.

We understand the inconvenience and we appreciate your patience and understanding while we complete this necessary maintenance to keep our sanitary sewer system in proper working condition.
