The organisation IDE in Asia is developing several models of plastic-lined tanks. One model consists of a 1500-litre reinforced plastic bag that fits inside a cylinder of sheet metal. Another model is a plastic liner reinforced with a 10 m3 plastic bag and installed in a hole in the ground.
Open storage tanks can be made of earth. If clay is not available, a plastic lining is needed to stop water from leaking away. Linings can be made of standard plastic sheet glued together with the tar normally used to repair roofs. The plastic must be covered with earth to prevent it from being exposed to the sun.
