How to Prepare Your Septic Tank for Colder Temperatures

Man working on septic tank on property with frosted grassDo you have a septic tank that drains waste on your property? Winter is coming, and there are some things you can do to help prepare it for the colder temperatures associated with the chilly season.

Professional Inspection

First, consider having your septic tank professionally inspected by Carolina Septic Pro. This way you’ll know exactly how it’s currently doing, and if it needs to be pumped out or not.


Next, you might want to consider adding antifreeze into the septic tank system; Don’t use automotive antifreeze for this– instead, get antifreeze that’s specifically designed for septic systems.

Drainfield Tips

When it comes to the drainfield area, don’t park vehicles on it. Avoid cutting the grass low. Taller grass (6 inches+) will help attract and preserve snow, which acts as insulation. The tall grass alone also serves this purpose. If you want, add straw or leaves onto the grass over your drainfield for even more natural insulation. Stores sell frost blankets. These can be used to help further insulate the septic system, too– they’re waterproof and trap the heat of the soil thereby reducing freezing problems associated with frost. Frost blankets also work well when you want to cover shrubs and gardens in your yard.

Routine Usage

Finally, be sure and use your system during the winter. If you’re going away from your house for an extended period of time, have a neighbor or friend run your faucets (ideally with warm water) and flush your toilets every couple days. This will help prevent the system from freezing up.
