In this study, urethalate floating cover is designed using soft drinks bottles and foam polyurethane in order to prevent evaporation losses of water reservoirs of Sarcheshme Copper Complex. Designed urethalate is including four square coatings with two layers of bottles that foam polyurethane is injected into these coatings to maintain and shaping and liners of anti-acid concrete has been created on its surface to protect of the upper layer. For evaluating the performance of two layer urethalate cover to reduce evaporation, two ponds with an area of nine m2 in the vicinity of Sarcheshmeh tailing dam were constructed and then the evaporation losses was measured for two month in each pond. The obtained results using designed cover showed performance of two layers urethalate in evaporation reduction. More than 92. 5% of the expected evaporation was reduced. Due to the durability and performance of urethalate, this project can be considered as a worthwhile project to be used elsewhere. It would also be a useful application of environmental waste material to save water in the region with water scarcity in Iran.
