In case of a hurricane event, the tower can be lowered down to the ground by 4 people in 30 minutes and stored in a safe place.
Warka Warka installed in Ethiopia is estimated to last from 6 to 10 years. The maintenance of the structure is very important to guaranty a long duration. It is important to check-up regularly the correct functioning and apply the maintenance needed to keep Warka operative such as replacement of filters, mesh reparation, ropes regular tightening and bamboo element substitution when damaged. After the first pilot test will be tested we will have a better understanding of its durability.
