Neglecting to regularly inspect and clean the septic tank.
- Lack of understanding on the proper use of the system
- Poor soil conditions and/or faulty design or installation
- Over use – volume of water discharged exceeds system capabilities. I.e. more people in the house, or leaky faucet
- Unusually high water table, flooding the tank and/or the bed
- Tree roots clogging pipes
- Traffic over the disposal field breaking pipes
- Obstruction in the pipe between the house and the septic tank
