Concept & Technology

State of the Art Sustainable Technology

Crystal Lagoons has developed a pioneering, innovative, and environmentally sustainable technology that has been patented worldwide, which allows crystalline lagoons of unlimited sizes to be built and maintained at very low costs anywhere in the world, using minimal amount of chemicals and energy.

This state-of- the-art technology is environmentally friendly and enables the use of any type of water. Some of the advantages of Crystal Lagoons technology are:

  • It uses up to 100 times less chemicals than conventional swimming pool or drinking water treatment technologies.
  • It consumes only 2% of the energy needed by conventional swimming pool filtration systems.
  • It fully complies with the most stringent international physicochemical and microbiological water quality standards.
  • It enables low water consumption, using up to 30 times less water than a golf course and 50% less water than is required by a park of the same size.
  • By using the Crystal Lagoons evaporation control film technology, water consumption can be reduced even further.
  • Our lagoons can use any type of water: sea, fresh or brackish water, based on availability. This is very relevant, as sea and brackish water sources are found in abundance in the world.
  • Our crystal clear lagoons can capture direct rainwater, thereby reducing the need for make-up water to compensate for evaporation.
  • It gives value to, and enables the development of, previously unusable land.

Today, there are more than 50 million man-made water bodies around the world, such as golf course ponds, retention ponds, man-made lakes and lagoons, reservoirs, dams, and many others. None of them have the high transparency and clear water of swimming pools or tropical seas, but instead have murky water with a dark greenish color, due to algae proliferation and the accumulation of sediments on the bottom. For many years, different water treatment technologies have been applied in large water bodies to try to achieve high quality, such as the use of ozone, aeration and water jets, enzymes, biological equilibrium, fishes, and others. However, none of these methods created crystalline water bodies with high transparency and safe bacteriological conditions.

Therefore, Fernando Fischmann, founder of Crystal Lagoons and a biochemist by profession, sought to re-invent swimming pool technology in order to provide low cost methods and systems to implement and maintain large crystalline lagoons with excellent water quality at very low costs.

Creating Real Estate Value

Crystal Lagoons concept and technology, patented worldwide, have changed the real estate paradigm of ‘location, location, location’, becoming the World’s Top Amenity and adding enormous value to real estate projects.

Crystal Lagoons World's Best Amenity has managed to change the real estate paradigm of ‘location, location, location’ by creating idyllic beachfronts with crystalline lagoons of the highest water quality, in places that were previously unthinkable. Crystal Lagoons technology changes the landscape, generating a magical turquoise water environment that can be enjoyed year-round. This technology has brought about extraordinary, never before seen results, adding value principally in the following ways:

  • Creating an idyllic beach lifestyle waterfront, anywhere in the world, even in places nobody thought possible.
  • Making otherwise unviable projects feasible, making the impossible possible.
  • Generating considerably greater sales and property value.
  • Increasing the density of projects.
  • Increasing prices and occupancy rates in hotels.
  • Adding more value than any other known amenity.
  • Generating a competitive edge that eliminates nearby real estate development competition.

Competitive Advantage

The greatest advantages offered by Crystal Lagoons technology are its very low construction and maintenance costs, the use of any type of water source, and very low water consumption.

The sustainable technology developed and patented by Crystal Lagoons has become the World’s Top Amenity, and has improved people’s lives around the world.

One of the greatest advantages this technology offers are its very low construction and maintenance costs and its sustainable properties of low energy, water and chemical consumption, which have resulted in Crystal Lagoons today having a portfolio of more than 600 projects in different stages of planning, design, construction or operation in more than 60 countries worldwide.

The construction costs of a lagoon using Crystal Lagoons technology are very low, even less than that of a park of the same size. Furthermore, maintenance costs are very low due to the efficient use of chemicals and energy. This revolutionary technology also stands out because of its low water consumption, because it operates on a closed circuit, and only needs to compensate for water loss caused by evaporation. In comparison, one hectare of a crystalline lagoon consumes only 50% of the water needed by a park of the same size, and an average sized lagoon consumes around 30 times less water than a golf course.

Furthermore, the new Crystal Lagoons evaporation control film technology can be used in the lagoons, providing even lower evaporation rates and water consumption. For example, when using the Crystal Lagoons evaporation control technology, water consumption of an average sized lagoon may be reduced by up to 40 times less than for a golf course.

As an additional advantage, our lagoons can capture direct rainwater, thereby reducing the need for make-up water to compensate for evaporation. In some locations with high rainfall, it has been estimated that the lagoons can be refilled with just rainwater, practically not needing water to compensate for evaporation.

Additionally, Crystal Lagoons technology can use seawater, freshwater or brackish water, depending on availability.

Another important point is that these crystalline lagoons provide a safe environment that can be enjoyed by the entire family. This has even attracted people that do not normally practice water sports, as their idyllic beaches and paradise-like views provide pleasant, safe surroundings.

Water Treatment

Crystal Lagoons technology applies a pulse-based disinfection system that allows up to 100 times less chemicals to be used than are applied in swimming pools.

Conventional swimming pool technology requires high and permanent levels of residual chlorine or other disinfectants to be maintained in the water to keep the pool permanently disinfected and avoid contamination of the water brought by external agents such as bathers. Maintaining such high and permanent levels of chemicals in large water bodies imposes very high costs, making it non-viable economically. Also, it generates a high amount of DBPs (Disinfection- By-Products), which can be harmful to the environment. Therefore, it is not feasible to apply this disinfection technology in large water bodies.

The Crystal Lagoons patented solution is to apply controlled pulses of very small quantities of oxidants/micro-biocides to the water in the lagoon, according to the growth cycles of algae and bacteria, in very specific patterns based on algorithms. In so doing, it is not necessary to maintain a high and permanent level of disinfection. The results of this efficient system are that it enables up to 100 times less additives to be used than are used in conventional swimming pool and drinking water treatment, all of which reduces excessive expense on chemicals and further environmental damage.

The application of additives is coordinated by strategically located injectors and sensors. This operation is managed by the Crystal Lagoons Control Center through the internet, so it is not necessary to have skilled people on site to apply additives and monitor the water quality of the lagoon.

Also, Crystal Lagoons has developed and patented a new technology that enables the creation of different zones within large water bodies, whereby these zones can meet different water quality standards in order to comply with specific regulatory requirements.


Crystal Lagoons technology applies an efficient filtration system that uses only 2% of the energy consumed by conventional swimming pool centralized filtration systems.

Conventional swimming pool technology requires a pool's entire volume of water to be filtered between 1 to 6 times per day (generally 4 times per day depending on local regulations). For this, a centralized filtration system is used, which constantly captures water from the pool and filters this flow to recirculate the entire volume of water between 1 to 6 times per day in order to remove particles that produce turbidity. If this technology were applied to large water bodies, the filtration systems would be extremely big due to the large water volumes that would have to be filtered daily, resulting in a high impact on costs and physical space needed for its installation, which would make it impossible to use. Furthermore, the consumption of energy for the operation of filters and pumps would be enormous and at great cost. Therefore, the use of swimming pool filtration systems in large lakes and lagoons is neither economically feasible nor technically viable, as it would cause problems that are difficult to solve, such as the homogenous filtration of the water.

The Crystal Lagoons patented solution is to apply natural compounds and different ultrasonic waves to the water in the lagoon, which enable the contaminant particles to be agglomerated into larger particles that are later removed from the lagoon. This means that only a small portion of the total water volume needs to be filtered.

Therefore, the efficient Crystal Lagoons filtration system consumes only 2% of the energy used by conventional swimming pool filtration systems. Also, as the filtered flow is up to 300 times lower than conventional systems, the whole filtration system is smaller, decreasing installation requirements in terms of pumps and filter sizes.

Telemetric Monitoring And Operation

All of the lagoons using Crystal Lagoons technology around the world are monitored, controlled and operated remotely through the Crystal Lagoons Control Center (CLCC) via internet.

Specially designed systems and sensors continually report specific physicochemical and other water quality parameters through a proprietary telemetry platform, managed and operated through the cloud by the CLCC. All the different mechanical and hydraulic systems operating in the lagoons around the world are also activated and controlled from the CLCC, allowing for a constant monitoring and operation of the lagoons, to ensure excellent water quality all year round.

Floating Lagoons

Our patented technology allows floating crystalline lagoons to be constructed without using land, located in natural or man-made lakes with low water quality. Thanks to these floating lagoons, an idyllic beach paradise can be created and water sports can be practiced in a safe way, giving new value to spaces that could not be used for recreational purposes.

There are more than 50 million water bodies in the world that are not used for recreational purposes due to poor water quality or poor aesthetics. In the U.S. alone, there are more than 140,000 water bodies of this type. Our patented technology, floating crystalline lagoons, is changing this reality and generating a breakthrough worldwide by creating an idyllic beach life, where you can also practice water sports. This concept provides endless possibilities for use in lakes, dams, lagoons, rivers, bays and the sea with an attraction never seen before, in either private or public projects.

Imagine a city with bodies of water that are currently unused, which can become a unique attraction by including a crystalline floating lagoon. This can change and revitalize city life, providing a new and refreshing look.

Our floating crystalline lagoons apply our proven and patented water treatment technology to proprietary floating structures that are installed within larger water bodies, connected to land via floating decks and bridges. Different projects are currently being developed around the world.

Another relevant aspect is that these floating lagoons can also serve industrial purposes, creating floating cooling systems to provide high quality cooling water to power plants and other industrial processes.
