A complex and challenging project that was conducted in accordance with all the needs and rules of the profession while staying environment-friendly and using sustainable sources of energy, as well as being eco-friendly also in the field of waste water management.

At the time of construction, the Korčula pool was the largest project of its kind in southern Dalmatia. Due to its complexity and regional importance, the interest of all citizens in the project was extremely high. As the chief engineer and site manager, the owner of the Prosolis company Željko Gajić had a great responsibility and challenge ahead of him. In 2.5 years of project work, he was able to contribute with all his knowledge and his wealth of experience. One of the successfully realized challenges was the installation of a 34 m long wooden structure resting on a prestressed concrete structure. In addition to the most modern filter and mechanical system, solar panels have also been installed on the east and west sides of the flat roof of the pool building..

Solar panels were also installed in the Žrnovska Banja project.
