Why do some septic systems freeze up in the winter?
WhitePortA system used each day will typically not freeze unless there is a mechanical problem such as a sagged drain line.

A common problem is leaky water fixtures such as a dripping faucet or a high efficient furnace that drips condensation into the system.

This very small volume of water cools and freezes before it reaches the septic tank.

The easy solution is consistent use of hot water.

During winters of little snowfall, it’s important to cover your septic system and drain field with an insulating material such as natural straw or septic insulating blankets to avoid freeze up.
