Watermakers

Revolutionising Access to Fresh Water On-the-go

Watermakers have become an invaluable asset for long-distance sailors and those living off the grid on the water. Essentially, these devices transform seawater into potable water, ensuring a consistent, reliable source of fresh water during extended marine voyages. The importance of these systems can’t be overstated, as they afford independence from shore-based water supplies and enable extensive cruising in remote areas where fresh water is scarce.

The core of any watermaker is its desalination capability, which removes salt and other impurities from seawater. Various systems are available to suit a range of vessels, from small yachts to large ships. Whether you opt for a compact, portable unit or a more complex, high-capacity system, you’ll find that

watermakers can significantly enhance your self-sufficiency at sea. Selecting the right watermaker involves understanding how these systems work, their maintenance requirements, and the initial investment, which varies widely based on capacity and complexity.

Installation and upkeep are critical components to ensure your watermaker operates efficiently. While some systems are designed for the do-it-yourselfer, others may require professional installation and routine servicing to maintain optimal performance. Regular care will prolong the life of the watermaker and safeguard the quality of the water produced, ensuring that you have access to clean, sustainable, and drinkable water whenever you need it.

Key Takeaways

Watermakers allow for the production of fresh water at sea, enhancing self-sufficiency. 

Choosing the right watermaker depends on vessel size, water needs, and system complexity. 

Proper installation and maintenance are essential for efficient and sustainable watermaker operation. 

What is a Watermaker?

A watermaker is a desalination system designed to convert seawater into fresh, drinkable water. Using reverse osmosis technology, it removes salt, minerals, and impurities, providing a reliable water source for boats, yachts, remote islands, and land-based operations.

Types of Watermakers:

  1. Marine Watermakers – Used on boats and yachts to generate freshwater from seawater, reducing reliance on shore-based supplies.
  2. Land-Based Watermakers – Designed for homes, resorts, and remote locations needing sustainable freshwater solutions.
  3. Compact & Portable Units – Small-scale systems for emergency or off-grid use.

Watermakers are essential for long voyages, offshore living, and locations where freshwater is scarce, ensuring continuous access to clean, drinkable water.

The Process

1.


Seawater is drawn into the watermaker. 

2.


It undergoes pre-filtration to discard larger contaminants. 

3.


Prepared seawater is pressurised and pushed through the reverse osmosis membrane. 

4.


The desalinated water is then further purified if necessary. 

Maintaining your watermaker

Maintaining your watermaker is crucial for its longevity. Regularly check for clogs, clean the system, and replace filters and membranes as instructed by the manufacturer. Proper care ensures a steady fresh water supply, even amid the ocean. 

Why Watermakers Are Important at Sea

When you’re at sea, watermakers are a vital piece of equipment. They utilise desalination technology to convert seawater from the ocean into potable water. This process is imperative for long voyages where the supply of fresh water is limited.

Desalination works by removing salt and other minerals from seawater. Here’s a simple breakdown of the process:

  1. Seawater Intake: Seawater is drawn into the system.
  2. Filtration: It’s then filtered to remove large particles.
  3. Reverse Osmosis: High pressure forces the water through a semipermeable membrane, leaving salt behind.
  4. Freshwater Output: The desalinated water is now fit for drinking.

By generating fresh water on-board, you reduce dependence on reservoirs of stored water. This saves valuable space and ensures a continuous supply, which is paramount for extended trips or emergencies.

Additionally, watermakers can contribute to a sustainable water usage approach. You’re no longer solely reliant on shore-based water sources, which, in turn, helps to conserve those reservoirs.

Your boat becomes more self-sufficient when it uses a watermaker. It gives you the freedom to travel longer distances without the need for frequent stops to replenish your water supply. This autonomy enhances safety and convenience on the open seas.

Regular maintenance is key to ensuring the system works efficiently and provides clean, safe water throughout your journey.

How Watermakers Work

Watermakers utilise reverse osmosis technology to convert seawater into freshwater, suitable for drinking and other uses. This process hinges on using high-pressure pumps and sophisticated filtration systems to remove salt and impurities from seawater. 

Watermaker Desalination Process

The core of a watermaker is the reverse osmosis (RO) system. Here’s how it functions:

  1. Intake: Seawater is first drawn into the watermaker system.
  2. Pre-filtration: Seawater passes through a series of filters to remove large particles and debris. Think of this stage as a sieve that catches anything that’s not liquid.
  3. Reverse osmosis: The pre-filtered seawater is now forced through an RO membrane. This semi-permeable membrane allows only water molecules to pass through, leaving salt and other contaminants behind.
  4. Freshwater Output: The freshwater, separated from the seawater, is then collected and directed to a storage tank for your use.
High-pressure Pumps

Operation: The high-pressure pump in a watermaker propels seawater through the RO membrane with sufficient force.

Significance: This pressure—typically around 55 to 70 bar—drives desalination. Without it, reverse osmosis wouldn’t occur, as natural osmotic pressure would prevent freshwater from separating from the seawater.

HMaintenance: Regular pump maintenance is imperative to ensure the system operates efficiently.

Differences Between Watermaker Systems 

Watermaker systems are crucial equipment aboard vessels and in remote locations where access to fresh water is limited. Technology will significantly vary across different systems, influencing their portability, size, and reliability.

Portable Watermakers are lightweight and built for mobility. These units are ideal when you’re limited in space or need an adaptable water source. They often operate manually, so while compact, they may not be as reliable for producing large quantities of water as their larger counterparts.

Compact Watermakers strike a balance between size and performance. Typically electrically powered, they fit well on smaller boats or for users with moderate freshwater needs.

In contrast, Large-scale Systems suit permanent installations or vessels with ample room. They can produce significantly more fresh water and are generally more reliable over the long term due to robust construction and advanced filtration technology. However, these systems demand more maintenance and have higher initial costs.

When choosing your system, consider the space available for the equipment, your freshwater needs, and whether you require a solution tailored for occasional or constant use. While compact and portable options offer convenience, they might fall short in efficiency and reliability. On the other hand, larger systems, despite their lack of portability, guarantee a consistent and high-volume water supply. Always refer to the manufacturer’s guidelines to ensure compatibility with your requirements.

Choosing the Best Watermaker

Selecting the right watermaker involves understanding your specific water production needs, considering the energy it consumes, and assessing the acceptable noise level during operation. 

Capacity

Your watermaker’s capacity should align with your daily usage requirements. Evaluate the litres per day each system can produce:

  • Small Vessels: up to 120 litres per day
  • Medium Vessels: 120–760 litres per day
  • Large Vessels: above 760 litres per day

Choose a watermaker with a capacity 20% greater than your estimated daily use to ensure a reliable freshwater supply.

Energy Consumption

The efficiency of a watermaker depends on its energy consumption:

  • Manual Systems: low energy but labour-intensive
  • Electric Systems: higher energy use; check the wattage
  • Engine-driven Systems: tied to engine use; no separate power supply needed

Look for an energy-efficient system that balances power use with water output.

Noise Level

Noise levels can significantly affect comfort on board, particularly in smaller vessels:

  1. Low-noise Systems: below 60 decibels; suitable for smaller crafts
  2. Standard Systems: between 60–70 decibels
  3. Industrial Systems: above 70 decibels; for larger vessels where noise is less of a concern

Consider your tolerance for noise when selecting a system, keeping in mind that quieter units often result in higher costs. Prioritising maintenance ease can prolong the reliable operation of your watermaker while controlling long-term costs.
