  • Get It Pumped

This is arguably the most important step. We highly recommend having your septic tank pumped out before winter arrives. Septic tank pumping removes all the waste within the tank, including effluent that would otherwise freeze. Ideally, schedule your septic tank pumping before the ground freezes to ensure easier access. If that’s not possible, aim for early winter before heavy snowfall. We also recommend scheduling septic tank cleaning if it has been more than three to five years since your last cleaning.

  • Inspect Your Septic Tank System Before The First Snow And Ice Arrive

Before winter finally sets in, hire a local septic company to inspect your septic tank system and provide you with recommendations. The experts will look for cracks, leaks, or signs of pooling around the tank and drain field. It’s important to fix any issues in a timely manner to prevent further damage and potential water contamination. If you notice signs of trouble, schedule septic tank repair service with a professional septic company.

  • Reduce Household Water Consumption

Another precautionary measure you can take to avoid septic tank problems during winter is to limit water usage. This helps prevent the tank from filling up too quickly and potentially overflowing. Take shorter showers, fix leaky faucets, and run the dishwasher and washing machine only when full.

  • Spread 8-12 Inches Layer Of Straw Mulch Over The Entire Septic System Area

It's important to insulate your septic tank system from the cold to ensure it doesn’t freeze over. Spread mulch on the ground in the weeks leading up to winter. A thick layer of straw mulch insulates the tank, helping to promote bacterial activity.

  • Do Not Plow Snow Off the Top of Your Septic Tank

While this may seem counterintuitive, plowing snow can actually remove the insulating snow cover and expose the tank to colder temperatures. It’s advisable to leave the snow cover undisturbed. It acts as an additional insulator and protects the tank from accidental damage by plow blades.

  • Winterize Inlet And Outlet Pipes

Drain and insulate exposed pipes to prevent freezing and potential cracks. Consider using commercially available pipe insulation or wrapping them with old towels or blankets. You can call a nearby septic company to help you insulate the inlet and outlet pipes.

  • Mark the Septic Tank Location

Clearly mark the septic tank and drain field with stakes or flags, especially if they’re hidden under snow. Marking its location will help you find it easily for future maintenance or in case of emergencies. It also helps prevent accidental damage during snow removal or other winter activities.
