For a newly built greenhouse complex in Indonesia, two 2,29 meter high water tanks were installed. The tanks store water for the irrigation of strawberries. Pumped up water from a nearby well keep the water tanks filled.
The tanks were installed on a base of leveled concrete. The most sturdy and enduring type of foundation. The pitch is covered by a layer of sand, preventing sharp objects in the soil coming through. The sand layer also gives the liner some extra space to settle.
