Not necessarily. There are a few different ways you can use the WooWoo GT and GT LUX, depending on where it’s installed and the user experience the owner/operator wants to provide. 

If someone has just had a wee, there’s no need to add anything – most of the urine gets used in the composting process or is evaporated – anything remaining liquids may be discharged as a leachate and captured in a small container.

You can choose to either ask the user to add a scoop of wood shavings after each ‘solids’ visit, or you (as the owner/operator) can add an equivalent amount of shavings at the end of each or every other day. This makes the user experience really simple and removes any guesswork placed upon the user in terms of how much to add.
