However, for every five litres of purified water the system consumes around four litres of water. Instead of pumping all of this water back into the wetlands, the waste water is used to fill up giant tanks for fish farming. The fish, normally eaten only at special occasions, is distributed amongst our employees every month. We already produced more than 7500 kg fish. Thanks to these projects the number of cases of contagious diseases at the farm decreased by 50%!
