If you find your septic tank is overflowing at the tank this can indicate a blocked or broken outlet line or full soak hole, meaning that the water you are putting into the tank has no where to go so it is forced to flow out the lids or back up the inlet line causing your toilets etc to backup, this could be caused by multiple reasons like:
- Tree Roots in your outlet line
- If your outlet line runs through gardens or trees, the plants will run their roots towards a water source making their way into your outlet line causing a blockage
- Drain holes could be blocked with mud
- Over time mud can drop in and block up the drain holes limiting the ability for the water to flow out of the outlet
- Full Soak Pit
- Groundwater can affect a soak hole especially after a large rainfall, this can cause your septic tank to back up and potenitally overflow
- If your outlet T is broken inside your septic tank this can allow solids to flow down the outlet which can cause a blockage in the soak pit
