Why Composting Toilets

There are many levels to this question, and we will outline two fundamental concepts: the practical and the principal.

At a practical level, our composting toilets are hygienic, odourless, with simple maintenance, cost-effective, they look comfortable in the bathroom, and you are saving (annually per household) approx. 60,000L of fresh drinkable water from needlessly going down the drain.

By virtue of being waterless, our composting toilets covert what would otherwise be widely dispersed pollution into a safe, natural humus soil. They just make sense.

Many people have chosen them for any of the following reasons –

  • They are practical option for a site with limited water supply, or where rocky or poor draining soil is present, or proximity to waterways prohibit traditional septic systems.
  • You might be looking for a low-maintenance, cost effective system for a new build or renovation.
  • You may be firmly committed to using ecologically sustainable ways of living, and are aware of the damage conventional waterborne systems are ultimately doing to our waterways, and you wouldn’t choose anything other than a composting toilet.
  • There is a need for a second toilet that will be cheaper than connecting to an existing septic tank, or have a batch, garage/workshop, farm shed, and minor dwellings etc., which have a minimal use.
  • You may be a council member looking to promote a sustainable image at a council level, or a developer, focusing on public facilities which can cope with variable use and minimal maintenance.

Whatever your reason, between our products, we are confident that we can offer systems which can suit your needs, whether domestic or commercial in scale. And you have our full after-sales support!


Why Waterless?

In principal, WCTNZ promote composting toilets with the emphasis on waterless. There is no need to combine two individually recyclable resources together, which creates a unified waste that travels, and then to go through the expensive and not 100% effective process of trying to separate the water from the waste after the fact. It seems counter-intuitive, and we are living in a world which results of this error in this thought:

“The squandering of our water resources and pollution from sewage and synthetic fertilisers, results in part from the belief that humanure and food scraps are waste minerals rather than recyclable natural resource – waste is a human concept, and does not exist in nature.

“The practise of injecting waste products and toxic materials into the arterial waterways of the earth is comparable to the idea of using our own bloodstream as a disposal site for hazardous compounds.” – Keith Helmuth

“Every time we flush a toilet, we launch ½ – ¾ litres (in modern water-saving flush loos) of polluted water out into the world…even after the contaminated water is treated in wastewater treatment plants, it may still be polluted with excessive nitrates, chlorine, pharmaceutical drugs, industrial chemicals, detergents, and other pollutants. The ‘treated’ water is then discharged directly into the environment.” – Jack Golden, The Environmental Impact Data Book

“Compost toilet systems are now becoming internationally recognised as constituting ‘proper sanitation’ and are becoming more and more attractive throughout the world due to their relatively low cost, when compared to waterborne systems and centralised sewers. In fact, compost toilet systems yield a dividend – Humus, which allows such as system to yield a net profit, rather than being a constant financial drain (no pun intended).

“A single person using a Clivus Multrum will produce 40kg of compost per year, while refraining from polluting 25,000L of water annually.* When one considers that only 3% of the Earths water is not salt water and 2/3 of that is locked up in ice, that means less than 1% of the Earths water is available to us as drinking water – why do we insist on spoiling it with fecal matter?” -Joseph C. Jenkins, The Humanure Handbook
