2.0 INSTALLATION
2.8
Excess Liquid Drain Installation
The drainage system to be chosen depends entirely on the soil condition, ground water level, and local regulation. Two
drainage options for CM2 are recommended as below:
2.8.1
Option I—Absorption Trench
This is the normal method for disposal of excess liquid, but refer to council for permit for any specific
requirements. These instructions apply to installation of the drain kit items available from Clivus Multrum.
1.
Dig a trench in a position located in front of the liquid end product drain.
2.
The trench is to be located in soil of good permeability and in a position where ground water will not
flood the unit.
3.
If there is some doubt as to the permeability of 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 grey water
system or an alternative disposal method complying with AS/NZS 1547:2012.
Trench dimensions and construction are to be in accordance with AS/NZS 1547:2012, as shown in Figure 5.
Figure 5: Durable self supporting arch trench
This option is for installation with high ground water level, poor permeability or rocks.
Figure 6: Translucent Container 25 Litre Capacity
Excess liquid can be drained into the container. When filled, remove and dilute 1 to 4 with water and use as fertiliser.

Dimensions in mm.
It is important to ensure that the trench is level along its length. Ensure the liquid drain
pipe slopes away from the toilet. Trench should be protected from surface water and
flooding, and vehicle traffic.
