Don’t Let Winter Catch You Off Guard: Will Your Septic Tank Survive the Freeze?

Septic tanks are an essential part of many homes and businesses that are not connected to a municipal sewer system. They play a vital role in treating wastewater and preventing contamination of groundwater and surface water. However, when temperatures drop below freezing, homeowners often wonder if their septic tank can freeze. The answer is yes, septic tanks can freeze, but it is not a common occurrence.

What is a Septic Tank?

A septic tank is a large, underground container that holds and treats wastewater from a home or business. The tank is typically made of concrete, plastic, or fiberglass and is divided into two compartments. The first compartment, called the settling chamber, allows solids to settle to the bottom of the tank. The second compartment, called the effluent chamber, holds the liquid that has been separated from the solids.

How Does a Septic Tank Work?

Wastewater from a home or business enters the septic tank through a pipe called the inlet pipe. The wastewater then flows into the settling chamber, where solids settle to the bottom of the tank. The liquid that remains in the settling chamber flows into the effluent chamber, where it is further treated by bacteria. The treated wastewater then exits the septic tank through an outlet pipe and flows into a drain field.

Can Septic Tanks Freeze?

Yes, septic tanks can freeze, but it is not a common occurrence. Septic tanks are typically buried underground, which helps to protect them from freezing temperatures. However, if the ground temperature drops below freezing for an extended period of time, the septic tank can freeze.

What Happens When a Septic Tank Freezes?

When a septic tank freezes, the wastewater inside the tank can expand and cause the tank to crack or burst. This can lead to sewage leaking into the ground, which can contaminate groundwater and surface water. In addition, a frozen septic tank can prevent wastewater from flowing into the drain field, which can cause backups in the home or business.

How to Prevent a Septic Tank from Freezing

There are a few things that you can do to prevent your septic tank from freezing:

• Insulate the septic tank. You can insulate the septic tank with a layer of foam insulation or straw. This will help to keep the tank warm and prevent it from freezing.
• Keep the septic tank lid closed. The septic tank lid helps to keep the heat in the tank and prevent it from freezing. Make sure to keep the lid closed at all times, except when you are adding bacteria or pumping the tank.
• Run water through the septic system regularly. Running water through the septic system helps to keep the tank from freezing. Make sure to run water through the system at least once a week, even if you are not using the system.
• Add bacteria to the septic tank. Bacteria help to break down the solids in the septic tank and prevent them from freezing. You can add bacteria to the septic tank by purchasing a commercial septic tank treatment product or by adding a gallon of fresh cow manure to the tank.

What to Do If Your Septic Tank Freezes

If your septic tank does freeze, there are a few things that you can do:

• Thaw the septic tank. You can thaw the septic tank by pouring hot water over the tank or by using a heat gun. Be careful not to damage the tank with the heat.
• Pump the septic tank. Once the septic tank has thawed, you should pump the tank to remove the frozen wastewater.
• Repair the septic tank. If the septic tank has cracked or burst, you will need to repair the tank. This is a job that should be done by a qualified professional.
