To keep our sewer lines clean, the Department of Public Works Sewer Division routinely conducts Sewer Jetting on all lines throughout Madison. This routine service in Madison has been occurring for over 35 years. We appreciate your continued cooperation as we maintain our critical infrastructure.
What is Sewer Jetting?
High-pressure water jetting, also referred to as "hydro-jetting" and "jetting", is a non-invasive process that forces water through a series of flexible hoses into sewer lines. The high pressure jetting can break up and flush out deposits that are blocking the sewer lines like sediment, grease, hair, mineral build-up, tree roots and debris. This process allows us to keep our sewer infrastructure clear and working properly.
Will this cause a mess in my residence?
With high pressure water being forced through a series of sewer lines, some smaller than others, backpressure created by this process may come up toilets, bathtub drains, and basement floor drains, causing small messes and inconveniences. To reduce the potential for messes, we encourage all residents to ensure their toilet seats and covers are down and drains are closed when jetting is scheduled to take place in your neighborhood. As jetting is taking place, gurgling within your toilets can occur - this is normal and should not cause any concern.
As mentioned above, this routine servicing of the lines has occurred for over 35 years. Although the probability of a mess occurring in your residence is low, we do encourage you to follow the recommendations above to eliminate the possibility for any issues.
Sewer Jetting began on October 3, 2021 and as of October 29, has completed a majority of the area (green). Jetting will be halted until November 8, when it will resume and finish the remaining area (red). Jetting will be concluded on or before November 19.
