Sanitary Sewer System
In serviced areas, the Township of Severn transports wastewater from your home through the sanitary sewer system to wastewater treatment facilities.
What are sewers?
Sewers are underground pipes that carry wastewater from homes and businesses to the wastewater treatment plants where it is treated and then released. Everything you pour down your drains or flush down your toilet goes into a sewer.

Frequently asked questions
How do you clean the sewers? |
We use a high-pressure nozzle to flush water down the sewer. The debris is removed through a maintenance hole by a large vacuum truck and taken to the landfill. |
How long does it take to clean the sewers on my street? |
It takes about one day to clean the sewer on each street. However, some sewers can take longer, depending on their size and condition. |
How should I prepare for sewer cleaning? |
During the cleaning, air pressure in the sewer may cause water to splash out through drains, sinks, and toilets. You should:
You can return these fixtures to normal when the equipment has moved off your block. |
Will I notice anything after you have cleaned the sewers? |
Sometimes the sewer cleaning and inspection leaves an odour in the home. If so, run water down the sink and bathtub drains, flush the toilets, pour a pail of water into each basement floor drain and open the windows. This should help the odour disappear soon after. |
Can I use the toilets and my water while you are cleaning the sewer on my street? |
Yes. But, be careful as air pressure in the sewer during the cleaning and inspection can sometimes cause water to splash out through drains, sinks, and toilets. Remember to close the lids on all toilet bowls when not in use and insert drain plugs in all sinks and bathtubs when not in use. |
How will I know when you are cleaning the sewers on my street? |
We will release a notice via our newsfeed and update this page. However, if we need to clean the sewer quickly because of a blockage, we won’t have time to let you know in advance. |
