How Do Waterless Toilets Work?
Waterless Composting Toilets (WCTs) are odour and chemical free as well as being completely waterless they offer a hygienic method of recycling human waste by separately managing your bodily wastewater (black water) from other wastewater such as greywater, you avoid polluting valuable clean water that can otherwise be put to better use! In New Zealand we have a lot to gain from Waterless Composting Toilets by significantly reducing our risk to discharge wastewater that may not be effectively treated thus protective our very sensitive environments.
