Test No. 2 is a reproduction of the conditions of a tank placed in the ground. The tanks are insulated outside the water surface.

After 88 days at an average temperature of 27 degrees Celsius, from 1.2 square meters of evaporation surface we saved 250 liters of water (23 cm.).
Looking at the forecasts for the coming years of temperature increase and lack of rainfall, every liter of water retained at the point of demand will be priceless. Droughts that have been occurring in recent years force us to look for ways to retain as much water as possible, even for watering crops (a 500 square meter retention tank with an installed ECO DYSK coating by KLIMEK-PLAST would save 104,166 liters of water in the same period. Looking at it on an annual basis, it gives us savings of 432,000 liters
