Sanitary sewer cleaning and televising

Sanitary Sewer



Hydro Klean is under contract with the City of Solon to perform cleaning and inspection of the City’s sanitary sewer system. In the next few days, crews will be cleaning and televising sewers. During this project we may need to access sewers and manholes in easements near your home. There will be little to no disruption to your sewer service during inspection.


Work is anticipated in your area between January 23, 2023, through February 032023, to those areas in ORANGE on the attached map.

During this process, we will insert a nozzle in the sewer lines and internally pressure-wash the system. This work can occasionally create “burping” or “hissing’ sounds in your residential lateral as air is attempting to escape the system during the cleaning process. You may notice an odor from the sewer and in rare cases, some water may splash out of drains or toilets. There are a few things you can do prior to cleaning to minimize these small disruptions:


  • Close your toilet lid. This will help to contain any splashing inside the toilet bowl.
  • Place a towel around drains. This will help to prevent any leakage if lines are pressurized.
  • Remove your sewer cleanout cap. If you have a service line cap near your house, removing that cap will relieve pressure and allow odors to escape. (Be sure to replace the cap after cleaning)
  • Run water after cleaning activity is finished. This will refill drain traps and prevent odors from rising through the pipes.


The vast majority of homes will experience no effects due this cleaning. However, some homes without adequate stack ventilation may experience some water and/or debris due to this vacuum effect. Stack ventilation is a home’s extension of the internal waste pipe(s) to an outside point of the home to maintain atmospheric pressure within the home’s waste removal pipes. The homes with higher risk of this occurring are older homes initially designed with little or no stack ventilation and/or newer homes with poorly maintained stack ventilation (which can result from nests, leaves, or other debris clogging the stack vent). If you feel your home may be at risk, it may be a good idea to discuss with a plumber to ensure 1.) your existing vent stacks are well maintained and 2.) your existing venting system is up to building code to prevent such backups and/or sewer gases from entering your home. Unfortunately, there is no way to tell which homes will be affected but experience has shown that a few homes are affected with each project.


If you have any questions or concerns, please contact Veenstra & Kimm, Inc. at (319)-466-1000.
