Every installers worst nightmare, the Klargester that has popped out of the ground! 

More often than not this is due to incorrect insallation conditions. This would happen if the water table was too high for the position of the system or if the system is installed with granular material rather than concrete. Always follow the installation guidelines to avoid these devastatingly costly mistakes.

If you are planning on installing a septic tank or sewage treatment system yourself it is important you are aware of the general binding rules. If in doubt leave it to a waste water specialist.
