Excess Liquid Drain Options

The drainage system to be chosen depends entirely on the soil condition, groundwater level, and local regulation.

Two drainage options are recommended as below:

Absorption Trench
This is the normal method for disposal of excess liquid but refer to the council for a permit for any specific requirements.

OR

Holding Tank
This is suited for the use of a CM2 in mobile homes or campers.

1. Dig a trench in a position located in front of the liquid end product drain.
2. The trench is to be located in the soil of good permeability and in a position where groundwater will not flood the unit.
3. If there is some doubt as to the permeability of the soil, extra trenching length may be required especially if a hand basin or other fittings will also drain to the same trench.
4. The liquid leaving the compost unit when in use is not expected to exceed 1 litre per day per resident.
5. In some locations it may be desirable or necessary to connect the excess liquid drain to a greywater system or an alternative disposal method complying with AS/NZS 1547:2012.

Note; Trench dimensions and construction are to be in accordance with AS/NZS 1547:2012
