Allow us to showcase an operational installation on the British Virgin Islands by sharing its real-time performance. While only using 12 kWp of installed solar panels, the system is designed to produce 12,500 liters or 3,300 US gallons of fresh water from seawater on a daily basis .

This installation saves the end-user 63% on the costs for water, while at the same time avoiding the yearly emission of 25 metric tons of CO₂. Enjoy the live performance from anywhere around the world and familiarize yourself with the different components.

The project was kicked-off with a personal intake with the team of Elemental Water Makers, in which the clients requirements and demands were defined. This resulted in a tailor made project proposal, containing the footprint, costs, time-line for implementation and organization of the operations and support. Through close collaboration, this proposal was converted into a supply agreement to implement the solution. The project was carefully prepared and executed, through frequent communication with the client. The team of Elemental Water Makers managed the implementation process and delivered the turn-key solution which generates fresh water, while only using the sea, sun and earth. Local personnel have been trained to execute the maintenance tasks and through real-time remote sensing the water quality and reliability are assured.

Water Supply for private estate Diamond Reef Limited

British Virgin Islands

My family and I selected Elemental Water Makers to provide fresh water for our home in the British Virgin Islands because they presented us with a cost effective solution to creating a continuous supply of very high quality water -- without monthly electrical bills and without using fossil fuels. Their technical people listened carefully to our needs, were a pleasure to work with, and in the end designed a custom solution that works as promised.

After struggling for years with high electric costs, power outages and the unreliable water quality and volumes produced by our home's traditional reverse osmosis system, we now enjoy more than 3,300 gallons of fresh water every day, using nothing more than sunshine and the natural elevation of our property. And in the process, my children and I are helping to reduce the Virgin Islands' carbon footprint and preserve its precious environment for future generations.

We would recommend Elemental Water Makers without hesitation.

Water Supply for Eco Lodge


For a remote eco lodge in Mozambique we have secured a fresh water supply of 9000 liters or 2378 gallons per day from seawater. Although this is a relative small water production capacity, the unit operates on a Specific Energy Consumption below 2.5 kWh/m³ water produced. The compact Water Makers has been connected to the existing energy supply and features GSM based monitoring, control and alarm messaging, much suitable for rural areas. All components are purpose built to survive corrosive environments, ensuring an independent, reliable and affordable access to safe water in Mozambique.

Water Supply for Private Island


Water is the passion of island owners. It's an essential part of the stunning vistas and the key to privacy to the rest of the world. But it also creates an expensive sustainability issue, because the majority of the water covering the planet is undrinkable. Reverse osmosis, the most popular form of converting salt water to fresh, requires high consumption of electricity, which is not a reliable or environmentally sound option for remote islands.

For a Private Island owner in Belize, we have supplied a compact energy efficient desalination solution that produces 4800 liters or 1268 gallons on a daily basis from the surrounding seawater. During its operation, it only consumes 3.5 kWh/m³, which can be easily generated from solar panels using the ample sunshine. 'Fresh water has never been so easily obtainable or this free of guilt'.

Water for Eco Resort


This particular resort has an ethos to embrace their guests in an alternative holiday experience, showing them that you do not have to forsake modern facilities, rich comforts and concepts of luxury in order to have a responsible and sustainable tourist experience. The fifteen environmentally friendly holiday yurts, villages and cottages are off-grid, powered by solar and wind energy. The last step in making this eco resort fully sustainable is to arrange an independent water supply. We are currently preparing the installation of the solar and wind powered desalination solution, that will generate safe and reliable water using unlimited resources for all guests and animals. The unit has a payback within 3 years and will save over 50% on the water costs.

Preparation of water intake for water supply for Condominium


What do you do when electricity is expensive and the piped water network is expensive, unreliable and of limited quality? This condominium requires over 8500 gallons or 32 m³ on a daily basis. This means that the cost saving we offer are huge. The solution that we are implementing results in a payback within 1 year. Currently, we have provided the water intake pump to prepare the well for the desalination solution, which is the next step to start enjoying a reliable supply of affordable fresh water.

Improving seawater intake for Desalination

British Virgin Islands

We have improved the seawater intake for an existing desalination solution for a private island in the British Virgin Islands. The old seawater intake faced much turbidity, leading to frequent replacement of the pre-filtration and reverse osmosis membranes. It also used much energy, which directly involves high cost. We were able to restore an open ocean intake, improving the feed water quality and energy efficiency. The next step will be to implement an energy efficient and renewable energy driven desalination solution.

Field Pilot for Plant Nursery

Indonesia, Bali

At this location we have constructed a small-scale pilot that produced 2.5 m³/day or 660 gpd from brackish groundwater, using only the energy from 640 Wp of installed solar panels. This project has been the result of a cooperation between the University of Technology Delft, The Netherlands and the Institut Teknologi Bandung, Indonesia and has proven the working principle of Let Nature do the Work. The project has won several prestigious innovation awards.
