Waterless, Odourless, and Completely Off-Grid. The WooWoo GT is your Perfect High Capacity, Low Maintenance Composting Toilet Solution!
The WooWoo GT 120 and 330 composting toilets are completely off-grid, requiring no water or electricity, yet provide a simple, odourless experience for the user and are simple to service and maintain for the owner.
Composting takes place within the container (known as batch composting) and the unique capillary base system ensures that optimum moisture levels are maintained by allowing excess leachate to drain out when there’s too much (either to a container or a soak-away pit), or by drawing it back up into the composting mass if it gets too dry.
The WooWoo GT Starter Packs come with two containers, so one can be composting whilst the other is in use. If you need to extend your capacity, you can purchase additional containers.
Unique Capillary Base - Automatically Regulates Moisture Levels
To promote rapid composting, controlling the moisture level is key.
The WooWoo GT does this with the unique capillary base which automatically allows excess liquids (leachate) to drain out if the composting mass is too wet, and conversely, draws moisture back up (from the lower sump) if it’s too dry.
This amazing, yet simple technology is a spin-off from the horticultural industry and is unique to the WooWoo GT products.
So Easy to Use!
For the user, they just ‘go’ as they would with any other toilet – the only difference is that after each solid use, a scoop of wood shavings is dropped in.
Because this isn’t based around a urine separator, the user can’t do anything wrong – it’s child friendly, female friendly, and men can stand up to urinate!
The wood shavings provide the carbon to go with the nitrogen in the urine/faeces, and together with some moisture and oxygen, they make the perfect compost recipe!
The simple nature and ease of use makes the WooWoo GT ideal for forest schools, allotments and glamping/camping sites.
And, Easy to Maintain!
The WooWoo GT and WooWoo GT LUX starter packs comes with two containers (either 120-litre or 330-litre) – when the first one is full, pull it out from the building and swap with the empty one. The full one is set aside to complete composting.
When the first one has sat for long enough, you can empty the safe, odour-free compost and use it around trees and bushes, cycling nutrients back into the earth.
Odour-Free
Almost from the first use, the composting process will start, as our wonderful and naturally-occuring bacteria friends will be busy converting the contents into a safe, sweet smelling, beneficial compost, and as they work, they also reduce the odours too. A passive (non-electric) ventilation system draws any remaining odours up and away, aided by the free-spinning wind vent.
An optional electric ventilation system can be used where the WooWoo GT is placed inside a dwelling as opposed to a well-ventilated shed or outbuilding.
Porcelain Pedestal Option
The WooWoo GT LUX package comes with a beautiful porcelain pedestal for the ultimate in ‘home comfort’.
The GT LUX will require a slightly higher floor level to give enough room for the composting container below.
In addition, the GT LUX comes with an electric ventilation fan to ensure a totally odour-free experience together with the familiarity of a porcelain toilet pedestal.
Install it Your Way
As a batch composting system, the WooWoo GT containers will probably require you to create a structure around them to suit your style and taste.
Above the active WooWoo GT container is an adjustable chute that connects the container to the underneath of the toilet bench. You can use the included polystyrene seat (very warm in winter!) or any other toilet seat if you prefer.
If you need help, you can download FREE plans to make your own building, or we can supply a range of WooWoo GT Cabins as flat-packs for you to install and paint/finish in any way you choose.
High-Capacity & Extendable
The WooWoo GT and GT LUX starter packs comes with two containers, so when one is full, it’s moved out of use and the new one brought into play. The full container can now continue to compost for six months or more, so when it comes to emptying, you’re only handling safe, odour-free, finished compost.
The GT 120 has a capacity of around 225 solids uses per container, whilst each of the GT 330 containers can handle around 800 solids uses. It’s possible to have an unlimited capacity by buying more containers
Warmer weather will generally extend the capacity of the WooWoo GT system due to increased evaporation and accelerated composting.
Single, Double or Accessible - Self-Assembly Cabin Options
If you’re keen to get up and running quickly, we can supply a single, double and an accessible wooden cabin that works perfectly with the the WooWoo GT 120 or GT 330 starter kits. These self-assembly cabins are designed and manufactured in Finland and feature a distinctive round window in the door. Delivered kerbside on an oversized pallet, they come complete with a lock and key, roofing felt and shingles. Find out more by clicking on the images below.
Genuinely Kind to the Environment
Depending on type of use and ambient temperature, a small amount of liquid ‘leachate’ may be discharged from the WooWoo GT system. This comes out of a flexible pipe at the base and can be run into a small soak-away pit, or where this isn’t possible, it can be captured in a small container that will need checking on a weekly basis.
The only other thing that comes out is compost! Because the ‘ingredients’ are added in a controlled way (nitrogen from the human waste, carbon from the cover material) with air and moisture all balanced, you have the perfect environment for composting to take place.
Completely Off-Grid
The WooWoo GT needs no water or electricity*, so it’s truly off-grid, waterless and can be installed almost anywhere.
With it’s simple but clever capillary base design and free-spinning wind vent, the WooWoo GT system harnesses the power of nature to create a low-maintenance, highly efficient batch composting toilet system.
* Installations within a dwelling (ie more air-tight buildings) should be installed with an electric ventilation fan.
