Stop the Freeze: Can Septic Systems Withstand Sub-Zero Temperatures?

A septic system freeze occurs when the liquid waste in your septic tank and drainfield freezes due to extremely cold temperatures. This can lead to several problems, including:

• Clogged pipes: Frozen waste can block the pipes leading from your home to the septic tank and drainfield.
• Septic tank damage: If the frozen waste expands, it can crack the septic tank.
• Environmental contamination: If the frozen waste overflows from the septic tank or drainfield, it can contaminate the groundwater and surface water.

Can Septic System Freeze?

• Insulation: Septic tanks and drainfields that are properly insulated are less likely to freeze.
• Location: Septic systems in colder climates are more likely to freeze.
• Age of the system: Older septic systems are more susceptible to freezing.

How to Prevent Septic System Freeze
