Keeping your Septic System Functional During Winter

If you are a home owner living on a septic system, there are some precautions you should take to prevent a frozen septic system during the winter months. In Victoria, we are fortunate we don't have to worry about this issue as our winters are quite mild, but others within Northern British Columbia and other places in Canada may encounter these issues.

Keep in mind that septic systems that are frequently used are less susceptible to freezing because of the constant water flow. Systems which aren't in constant use, or lay dormant for a period of time, are more likely to have issues in colder climates.

Common Causes of a Frozen Septic System

  • No insulating layer or cover for your septic system will allow the frost to go deep into the septic components, eventually freezing the entire system and filling beneficial bacteria.
  • Snow compaction. Snow cover is helpful as long as it is not significantly compacted. Snow that has been compacted from vehicle or foot traffic can drive down frost and increase the chances of freezing.
  • A long interval of not using the septic system at summer cabins or homes that are not used during the week.
  • Leaks in the plumbing systems allow water into the system that can eventually freeze.
  • Poor drainage in the pipes.
  • System is waterlogged.
  • If the system is uncapped or open, cold air will enter and freeze.

How to Prevent a Frozen Septic System During Winter

  1. Pump out your septic on a regular basis.
  2. Remove trees and other hardwood plants over or near your septic system. Roots could penetrate your system and block the normal flow of the wastewater.
  3. Dispose your waste properly. Check out our list of 9 things you should NEVER flush down the toilet - Living On a Septic System
  4. Without bacteria, there is no wastewater treatment. Use eco-friendly cleaner instead of harsh chemicals.
  5. Refrain from driving over or building any structure over the septic system.
  6. Place a good layer of mulch over your septic if you're system is prone to freezing.

What to do if your System Freezes

Unfortunately, the first major sign that your septic system has frozen is raw sewage will begin to back up into the house. If this occurs, immediately shut off all running faucets, laundry machines, dish washer and the well pump. Next, contact a professional pumper or installer to identify the point of freezing and correct the problem.

THINGS YOU SHOULD NEVER DO TO A FROZEN SEPTIC SYSTEM:

  • Do not add antifreeze, salt or additives
  • Do not start a fire on the ground above where the tank is located
  • Do not continuously run water to try to thaw frozen pipes
