Access to clean, reliable water is never guaranteed in off-grid locations. Maybe you’re relying on rainwater tanks, trucked-in water, or diesel-powered pumps to stay afloat. But these systems often fall short. That’s where solar-powered desalination makes a difference. It offers a dependable way to produce clean, safe drinking water without fossil fuels, chemicals, or grid electricity. The result? Zero-emissions water production – no noise, no fuel bills, and no carbon footprint.
At Bluemont, we supply 100% solar-powered desalination systems built for tough off-grid conditions across Australia, New Zealand, and the Pacific Islands.
Solar desalination is water security without the carbon footprint.
Water Supply Challenges in Off-Grid Areas
Water security in remote or off-grid areas isn’t just about comfort – it’s essential for day-to-day operations in homes, businesses, and communities. Traditional systems often fall short because:
- Rainwater tanks run dry during droughts or erratic rainfall – now more frequent due to climate shifts.
- Shallow wells and bores are increasingly brackish or salty, especially in coastal areas and low-lying land. Treating this water often requires chemicals that may raise health concerns.
- Diesel-powered pumps are expensive, noisy, and require regular servicing – while also contributing heavily to carbon emissions.
- Trucked-in water may be the only option for some properties, but it’s costly, unreliable, and adds logistical headaches.
And then there’s the environmental cost. Fossil fuel-based systems don’t just burn through your budget – they burn through the planet’s carbon budget, too. With growing awareness and tightening emissions targets, there’s more demand than ever for clean, sustainable alternatives.
Solar water desalination answers that call.
Why 100% Solar Desalination Is a Smarter Off-Grid Solution
If your property is close to the coast or has access to brackish or saline water, switching to solar desalination can be a game changer. It’s clean, reliable, and fuel-free – cutting your carbon footprint dramatically, even to zero if you go fully solar.
Here’s how it helps:
Off-Grid and Fuel-Free
Solar-powered systems eliminate the need for diesel or mains electricity. That means no rising fuel bills, no delivery delays, and no dependence on outdated infrastructure. Just solar panels – and total independence.
Reliable Daily Water Supply
The systems run on solar but can include battery backups to keep the water flowing at night or on cloudy days. Whether it’s for a home, batch, or remote project site, you’ll have safe, consistent drinking water.
Zero-Emissions Water Production
With no fossil fuels in the mix, there are no CO₂ emissions – helping New Zealand reach its net-zero targets and keeping your water supply in line with a cleaner future.
Chemical-Free Clean Water
Bluemont’s Elemental Water Makers use reverse osmosis and a patented energy recovery system – no chemical additives required. It’s a safer, simpler approach to water purification.
Lower Ongoing Costs
Once installed, the system is low-maintenance with no ongoing fuel or chemical costs. High-efficiency parts and low operating expenses mean long-term savings.
How Does Solar Desalination by Elemental Water Makers Work?
At its core, EWM solar desalination combines two clean technologies: solar energy and reverse osmosis.
Here’s how it works, step by step:
- Solar panels generate electricity from sunlight during the day. This powers the entire system, including pumps, controls, and the desalination process.
- Saline or brackish water is drawn from a nearby source – typically seawater or groundwater with high salt content.
- The water is pushed through a reverse osmosis membrane, a fine filter that separates salt, minerals, and other impurities from the water molecules.
- The result is clean, drinkable water on one side, and concentrated brine (saltwater waste) on the other.
- The system uses a patented energy recovery unit that captures energy from the outgoing water flow and feeds it back into the process – reducing overall energy use by up to 70%.
- For night-time or low-sunlight hours, battery storage provides backup power so water production stays consistent.
Off-Grid Solar Desalination Solutions
We offer a range of scalable, solar-powered desalination units suited for different needs across New Zealand:
Large-Scale: Elemental Water Source
A pre-configured, containerised system that runs on solar or wind power. Ideal for island resorts, coastal communities, or large off-grid farms and homes. Includes:
- Built-in solar panels and batteries
- Reverse osmosis technology
- A patented energy recovery system that reduces energy use by up to 70%
- Zero reliance on grid power or diesel
Small-Scale: Elemental Water Response
A compact, portable, solar-powered system for emergency response, mobile teams, or seasonal use. It’s:
- Lightweight and easy to set up
- Fully off-grid
- Chemical-free and safe for drinking
- Flexible – can also connect to other power sources if needed
Built for New Zealand’s Harsh and Varied Conditions
From coastal salt spray to strong winds and shifting weather, our systems are built tough:
- Resistant to salt exposure – ideal for island or beach locations
- Rugged, modular designs – easy to transport, install, and scale
- Intuitive to operate – no special training required
- Optional remote monitoring for peace of mind
Whether you’re managing a farm in Northland, building a remote eco-lodge in the Sounds, or supporting a coastal community on the East Cape, our systems are ready.
