The Chove Chuva system is the only one that treats rainwater for domestic use. The equipment separates the water from the waste, leaves and particulate material of greater proportion and passes it through limestone for pH adjustment. In the third stage, the water comes into contact with chlorine tablets to eliminate harmful microorganisms and ends in a finer filtration system to clean any impurity that still exists in the water. After passing through the Chove Chuva phases, water can be stored in underground or surface cisterns to be used in various parts of the house or company.
