CLEANING AND INSPECTION OF 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 03, 2023, 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:
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.
