Nusa Island Retreat is an island playground that’s right in the middle of paradise. Located on Nusa island in the subtropical region north of Papua New Guinea, it’s a remote and beautiful part of the world.
Given that the resort is located on an island and it’s fairly isolated, a sustainable and easily manageable toilet system for their cabins was a necessary requirement when researching environmentally friendly toilets.
Nusa Island Retreat approached Clivus Multrum with their requirements. The toilets had to be:
After talking with a few different waterless toilet system companies, the Nusa Island Retreat decided on us for their composting toilet systems for their cabins.
Elle wanted a system that was as environmentally friendly as possible. An off-grid composting system that required minimal power input from her solar system was the logical choice. "Originally I had another in house system that required too much maintenance, and the Clivus Multrum system was a far better choice for my set-up."
"It has been a diverse set of responses. Some people are surprised that it doesn't smell at all, and others have been surprised that the local council have allowed it. I've had some friends pull me aside quietly and asked me how to use it, which I expected. Overall, the response has been positive and most like the idea.
Most people are curious about how the system works, and I've been happy to take the opportunity to give them a demo. I run educational events in my tiny home, so I use my spare unit to demonstrate how easily you can manage a composting toilet. Three people who attended the events had said that they would now consider composting toilets when they hadn't considered a composting toilet before. A great outcome!" - Elle
Wondering if it’s legal to install a composting toilet in Australia? We cover things like state and local laws along with Australian Standards in this article.
Situated 15 kilometres north-east of Port Douglas, the Low Isles comprise a four-acre coral cay surrounded by 55 acres of reef within the Great Barrier Reef Marine Park, a UNESCO World Heritage Area.
Low Isles is also a popular tourist destination and attracts thousands of visitors per year. Existing facilities on the island include a composting toilet installed 20+ years ago. The existing facility is not coping with the visitor numbers and needs upgrading.
Low Isles is a highly sensitive site so any toilet system needed to have minimal impact on the site in order to preserve the integrity of the natural environment.
The existing toilet facility is not coping with the number of visitors to the island. A new facility is required that can cope with existing usage and future growth.
Low Isles is in a tropical cyclone area (Category 3) and can experience wind gusts up to 224kph.
There is no electricity or water on the island, so any new installation had to be stand-alone.
Low lsles is a remote site so the building kit had to be lightweight, easily transportable and easily assembled on-site with minimal equipment.
The Island is surrounded by saltwater and is a highly corrosive environment. Therefore, the building, fixtures and fittings had to be non-corrosive and durable.
Being a sand island, any new facility had to be 'self-cleaning' where possible and the stairs and floor material had to be non-slip.
Low Isles is an environmentally significant site. Therefore, any new facility had to utilise the existing building footprint and have minimal to no discharges to the environment when operational.
Ecoflo Wastewater Management supplied the complete kit with a local builder commissioned for the installation.
The complete kit included: 2 high capacity eco-friendly composting toilets - Clivus Multrum CM40 - with a design capacity of 80,000 visits per year. These are dry composting systems so there is no requirement for flush water.
A ‘Zero Discharge Facility’ incorporated into the design to create a ‘closed-loop’ system. The Facility is fully automated and operates using the supplied solar system.
Ecoflos’ standard 4 cubicle building module was used for this project. This was delivered to the Island as complete ‘flat-pack’ kit and included ‘marine grade’ stainless steel fasteners and Colorbond ULTRA sheeting. Highly durable fibre composite material (FRP) was used for all structural components. Slip-resistant FRP grating for the veranda area and stair treads was used to for safety and minimise sand buildup.
An FRP water tank stand with tank and the complete solar package was also supplied.
