Our REWAT technologies currently recycle 1,000,000 litres of water every day in the Czech Republic!

That is one million litres of water every day that would otherwise be discharged into the sewer system and replaced with drinking water in public swimming pools. This is not a plan, a study or a distant vision. It is a real, measurable result delivered by technologies already operating every single day. For us, this is a major milestone. At the same time, it is also a commitment to keep moving forward and demonstrate that water recycling has an essential role to play in modern water management.

As part of the reconstruction of the Vlašim swimming pool, the installation of the 18th REWAT recycling line is currently underway. The operator of the public sports facility will save 10,000 liters of drinking water every day, which would otherwise be consumed as part of the mandatory water replacement in pool operations. During the recycling process, no thermal losses occur, and therefore the technology not only saves water but also delivers significant energy savings for heating, along with a reduction in the carbon footprint.

Rewat Energy s.r.o. will take part in the MediWellness Congress 2026, taking place on April 27–28, 2026 in Geneva. This prestigious international congress will bring together the best of the wellness, spa, and health-oriented hospitality industry – from current trends and innovative technologies to new approaches to sustainable operations. The program will also include an expert presentation focused on sustainability and efficient water and energy management in wellness operations. If you are interested in attending, please do not hesitate to contact us – we will be happy to provide you with a discounted registration. We look forward to meeting partners and professionals from across the industry. More info www.mwcongress.com

In these days, Rewat Energy s.r.o. is initiating the installation of pool water recycling technology at the municipal public pool in city of Kravaře.The REWAT system will enable the operator to save up to 40 m³ of water per day, significantly reducing the consumption of drinking water as well as the costs associated with its heating and treatment.In addition to the economic benefits, the technology also contributes to improved pool water quality, thanks to its unique AOP (Advanced Oxidation Process) system.This project confirms a growing trend: modern aquatic facilities are increasingly combining visitor comfort with a responsible approach to environmental sustainability.

In August 2026, a new indoor swimming pool will open to the public on the Sports Island in Blansko. This modern sports complex will feature a stainless steel swimming pool with six 25-meter lanes, a training and relaxation pool, a whirlpool, and a pool designed for children from as young as six months.The technological solution will also include the REWAT pool water recycling system. With a recycling capacity of 50 m³ per day, the system will enable the city to save up to 18 million liters of drinking water annually, while also reducing the costs of water heating and chemical treatment. Another significant benefit is the reduced burden on public infrastructure, particularly the sewer system and the municipal wastewater treatment plant.This project demonstrates that modern sports infrastructure can go hand in hand with sustainable water and energy management principles.

At the end of February, we started the instalation at one of the most important sports facilities in the capital of the Czech Republic – the Slavia Praha Swimming Stadium.

This swimming complex welcomes children and adults from across Prague every day for swimming lessons and professional training. It is now taking a significant step toward sustainability thanks to REWAT technology. Within just a few weeks, young athletes can look forward to a more sustainable, more efficient, and safer environment for their training.

Thank you for your trust!

On January 31, 2026, Resort MELORI Aqua & Spa will welcome its first visitors and immediately rank among the most sustainable wellness resorts in Europe. From the very beginning, the project has been designed with a strong focus on reducing water and energy consumption while maintaining the highest level of comfort for visitors.

 REWAT has been involved in the project from its early stages, delivering advanced technologies for swimming pool water recycling, automation of pool operations, and energy-efficient solutions including heat recovery across the entire facility. Thanks to this integrated approach, MELORI Aqua & Spa sets a new benchmark for sustainable and responsible wellness operations in Europe.

We didn’t slow down at the end of the year. Just before Christmas, the city of Zábřeh received a new pool water recycling project.
The REWAT technology will recycle backwash water from both the indoor year-round pool and the outdoor pool during the summer season.

The result? Lower drinking water consumption, reduced energy costs, and a more efficient and sustainable pool operation—creating space for further development and modernization of the facility.

We will be at Piscina & Wellness Barcelona 2025!

Join us in Barcelona from November 17–20 to talk about sustainable pool and wellness solutions and water recycling technologies.

You can also meet us during these networking events:

November 17 – Andalusia Day

November 18 – Hospitality Design & Wellness Business

November 18 – Mexico Day

Let’s meet in the Business Lounge and explore how we can work together.

We’re excited to announce the upcoming installation of the REWAT OT20 technology, capable of recycling up to 20 m³ of pool wastewater per day.
The Třinec City Swimming Pool is joining the growing group of facilities who have chosen to embrace sustainability and operational savings with our REWAT technology.

We are heading to a congress and sports hotel in Prague, where our solution will support operations towards sustainability and responsible water management.

Thanks to continuous development, the REWAT technology now makes it possible to efficiently recycle even smaller volumes of water, making it an ideal choice for hotel and wellness facilities.

Within this project, we will significantly reduce drinking water consumption, energy costs, and the chemical load of pool water – which is more than desirable in a top-class relaxation and sports facility.

We have started the installation of our recycling technology in the newly built luxury wellness area of the Dolní Morava Mountain Resort. In this unique mountain environment, where resource conservation is of paramount importance, we save up to 80 m³ of water per day (more than 29 million liters per year). By recycling, we significantly reduce the consumption of drinking water, reduce the burden on sewage and wastewater treatment plants, and save energy by ensuring that water does not lose heat.

Mikulov has 7,630 inhabitants who consume approximately 687,000 liters of drinking water per day. The same amount is saved daily by public swimming pool operators who have installed REWAT pool water recycling technology. With an efficiency of more than 90%, REWAT recycles all the waste water from the washing of pool filters and returns it to the pool circuits without heat loss or the use of chemicals.

Did you know that producing 1 m³ of pool water and heating it to 26°C can produce up to 7.83 kg of CO₂ if you use electricity to heat it? If we use gas, it is still 4.57 kg CO₂/m³. A public swimming pool uses tens of cubic meters of water and thousands of kilograms of CO₂ every day just to ensure clean and warm water for visitors. With REWAT technology, we can not only recycle up to 90% of pool water, but also reduce emissions to a minimum. Recycling eliminates the need for new water production as well as unnecessary heating to higher temperatures. Every liter of recycled water not only saves precious natural resources but also our planet. This is a future worth fighting for!

Another recycling line has been in operation for several months in Tabor. The technology was installed as part of the reconstruction of the swimming pool. We save up to 65 000 liters of drinking water per day, which would otherwise be needed to refill our customers' pools due to hygiene regulations. 

After the successfully completed implementation in Ostrava, we moved straight to Františkovy Lázně, where the implementation of another REWAT recycling line was started. This time we will not only recycle wash water from pool filters. Thanks to innovative technology, our equipment will also contribute to a significant improvement in pool water quality and comfort.

One of the most important sports facilities in the Czech Republic has embarked on a journey of sustainability with us. At the beginning of April 2024, the installation of the REWAT OT 100 recycling line was completed, which will enable the city of Ostrava to save 35,000,000 liters of filling water for the 50m pool annually, along with the energy needed to heat it.

More than 1,000 engineers, students and other professionals from civil, structural, water and aerospace engineering gathered at the 7th World Engineers Conference in Prague. We are honoured that Rewat Energy s.r.o. represented the Czech Republic, not only with its exhibition, but also with a lecture in the programme on New Technologies to Combat the Consequences of Climate Change. We were awarded the honorary medal of the CSVTS for our fundamental contribution to the development of technical sciences. Rewat has thus become an important part of the technological fight for sustainability.

Want to learn more about our technology? Visit us at one of the trade fairs that our company regularly participates in. Invitations to trade fairs can be found in this section.

A few days ago we completed the implementation of the largest pool water recycling line in the Czech Republic. Aqualand Moravia saves 250 m³ of filling water every day by recycling the wash water from the sand filters using REWAT technology. Excluding heat losses, Aqualand Moravia recycles almost 90,000,000 liters of water per year, which corresponds to the consumption of drinking water in the Czech Republic in 5 days. We thank the most modern Aquapark in the Czech Republic for their trust and cooperation.
