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.

The organisation [http://ideorg.org ~~organisation~~ IDE] in Asia is developing several models of plastic-lined tanks.
