Kata Tjuta National Park

A World Heritage Area recognised for both its natural values and cultural values



Uluru-Kata Tjuta National Park is internationally recognised for its spectacular geological formations, rare plants and animals and exceptional natural beauty. Importantly, it is Aboriginal Land and is internationally acclaimed for its cultural landscape.

A very popular tourist destination, the park is located in a desert and receives an average rainfall of around 300 millimetres per year. Temperatures range from up to 45°C during the summer and -5 °C during winter.



The park needed toilet facilities that would cope with the extreme temperatures as well as the peaks and troughs in visitor numbers. Importantly, the cultural significance of the area and its fragile environment called for toilets that would leave a minimal footprint on the land.



14 standard and 2 disabled toilets with four CM40 tanks were installed at the visitor centre in 2009.

Kanyana National Park

Off grid toilets



Kanyana Park is a lookout point with beautiful views out over Moreton Bay. Approximately 16,000 to 20,000 people visit the park annually. There is only tank water on the site, no sewerage and no electricity so a composting toilet was the most practical and economical solution.



Satisfied with the performance of the original Clivus Multrum toilets, which had been destroyed in a fire, Sunshine Coast Regional Council decided to replace and upgrade the facilities. In 2011 new buildings were designed and built to accommodate two CM8 waterless composting toilets.



  • Save up to 50,000 litres of water a year that would be required for traditional flush toilets
  • Ongoing maintenance is minimal and at a low cost
  • The toilets are hygienic and odourless which makes for a pleasant experience for park visitors.

ESPOIR School of Life

The ESPOIR School of Life needed a toilet solution that didn’t need running water & wasn’t going to contaminate groundwater

The ESPOIR School of Life started in summer 2016 in Siargao, south of the Philippines. This important school will give children a set of core skills & values that will be useful in everyday life and help them to secure employment once their studies are completed. The school teaches children life skills such as respect, team-work, family, pride, love, tolerance & compassion.

The initial site where the school was built wasn’t really adequate for a proper learning environment as the facilities were too small and in a bad location. Nicolas Gontard & his wife (the founders of the school) approached the local mayor with the concept to build a new and better school.
The mayor was supportive and donated a parcel of land for the project. Nicolas & other private donors provided the funding whilst ESPOIR members sourced the materials and the labour to make it happen. The arrangement with locals was that the ESPOIR team would supply materials and expertise whilst the local families contributed sweat equity and elbow grease.

Here’s a few fast facts about the school:- 

  • A new school for the poorest of the poor.
  • Stage 1 will have one classroom and a Clivus Multrum (CM40) composting toilet. When complete the school will have 12-13 classrooms with 260 children at full capacity.
  • It is a free school that provides food and uniforms & well as a high standard of education.
  • It is in a central location so kids can easily & safely walk to school.
  • Funded through private donations.

Why ESPOIR chose a composting toilet

When the project team looked at all the different toilet options they knew there were some challenges they had to overcome. There was no sewage system operating in the area, the predominant toilet systems that were in use were septic tanks & pit toilets. The problem with these solutions was that in combination with high rainfall and water table close to the ground surface, contamination of groundwater was a major problem.

The project team did not want to contribute to this ongoing problem, so a composting toilet system provided a logical alternative. It was inexpensive to buy and install and low tech it was easy to use and crossed language barriers. In addition, a composting toilet system is a great way to demonstrate better and more sustainable approaches to managing human waste.

At this early stage, there has been very little resistance from the kids and the feedback from adults has been positive.
One person is responsible for the ongoing maintenance of the toilet and so far the ESPOIR team would not hesitate in recommending the system to others.



Railaco Kraic Village in East Timor

Supporting education and better living standards




Comunidade Edmund Rice (CER) was established in East Timor in the late 1990s and supports health, education and development projects in partnership with five remote communities, including the village of Railaco Kraic.

With some of the lowest economic indicators in the world and where 50% of the population is under the age of 18, education has been identified as key to prosperity for the area. Ensuring the retention of teachers in a remote area like Railaco Kraic is therefore incredibly important. However, a limited and unreliable supply of water and no electricity meant that facilities for teachers were very basic.


Solution and Benefits

A squat toilet was replaced with a CM8 toilet from Clivus Multrum. The toilet does not use water and only requires minimal solar energy to power a small fan in the vent pipe. It is safe, hygienic and requires minimal maintenance. Importantly, it has improved living standards for the teachers and continues to function well year after year.



Charles Sturt University

Charles Sturt University is well known for reducing it’s carbon and environmental footprint.


When we found out that the Charles Sturt University, Albury Wodonga campus was looking at reducing their environmental impact we knew that our range of composting toilets would easily meet their standards, be large enough to handle the capacity of the university and reduce the maintenance needed when compared to their current systems. Below is a run-down of how the system was implemented.

Number of units installed and size:

  • 2 x CM14 with one pedestal
  • 4 x CM14 with two pedestals
  • 1 x CM8 with one pedestal
  • 3 x CM14 with two pedestals
  • 2 x CM40 with four pedestals
  • 2 x CM8 with one pedestal
  • 1 x CM14 with two pedestals
  • 2 x CM20 with two pedestals

Facilities in which units are installed:
There are a total of 12 buildings with various combinations of toilets installed in each. Some bathrooms that were more frequently patronised needed larger storage units and needed to be able to handle shock loadings (large groups of visitors).


Was there any user resistance?
Overall the feedback has been very positive to the change of composting toilets. There was some initial apprehension to install these types of toilets in the cafeteria area & function centre but other than that the feedback has been very positive.

What are the maintenance requirements?
- Addition of bulking agent (Daily/Weekly)
- Raking & turning over of the humus as required.

What is your disposal method of Humus?
At this point we’re looking at putting it into an open trench on the property, treating it with UV & then we will spread it over the property.

What are your disposal method of excess fluids?
Excess liquids go into a greywater/blackwater wetland area. We use a pond stage water system & recycle on campus for irrigation.

What do you do with the grey water?
We use reed beds with three ponds to filter our grey water. Water flows into the first pond for UV treatment, we then filter it through the second & third ponds by which time it is perfectly OK to use on the property.

The last word:
Overall the experience is very positive, the toilets are working well & there are no problems or dramas.


The Environmental Management Plan for the campus which covers composting toilets


Kiabola Beach Primary School

In April 2017 three brand new Clivus Multrum composting toilets were installed at Kiabola Beach Primary School located in the Trobriand Islands in Papua New Guinea. This school has about 250 teachers and students and previously they have had to use pit toilets. This has obvious implications on sanitation, the environment and the senses.

When teachers at the school were asked “what is the main concern here at the primary school?” the response came quickly and with certainty – “SANITATION”. Hence the new toilet system which requires no water for flushing and ultimately provides the school with fertiliser for their gardens.

Below are some images from the delivery of the composting toilets through to the installation.
