Inside the main seat section there is a 25 litre solids collector that can be emptied by removing the top of the seat unit. The liquids are channeled away from the solids container by pipework and as standard the unit is configured to allow the liquids to soak away in the surrounding ground. However the unit can be configured to uses a urine collector on the exterior, should soak away not be possible in the chosen location. If you require this extra option, please contact us.
Because the liquids and solids are kept apart during use, this cuts odours considerably and keeps the Cooloo usable even when used by many people. A handful of sawdust, goes into the solids container before use and then another after. The sawdust helps to break down the waste and helps in the composting process. We suggest keeping a container full of sawdust in the Cooloo, along with a source of water, such as a large bottle as we suggest pouring a small amount down the liquid section after each use.
The unit itself is not used for composting the collected solids, so we always recommend getting a composting bin to accompany your Cooloo. Any standard composting unit will be fine and these are readily available and relatively inexpensive. Once the solids container is full, it can be emptied into the composting bin and over time the contents of the bin will turn into useful composting material known as Humanure. We recommend using biodegradable liners for the solids container as these can go in the compost bin.
Our unit is constructed from 18mm Plywood and the design of the construction means there are very few screws. Most of the supporting parts slot together for added strength. The roof of the toilet is made from pressure treated larch and keeps out all weather, but allows for good ventilation. There is a frosted acrylic window in both from door and the back wall and each unit has a hinged door with an inner bolt for privacy.
The main plywood comes untreated allowing you to apply your own weather proofing to the outside. A good waterproof seal and top coat will see your unit last many years. The roof ridge is made from folded aluminium.
The top section of the seat box can be easily removed for periodic cleaning.
