“Safe drinking water for all” has been a prime goal for responsible government since Man first formed social groupings. As a State ambition this aspiration should override other infrastructural considerations, for a Nation without safe drinking water will be a debilitated people plagued by disease. It is an unfortunate truism that conventional concrete water storage reservoirs are expensive and the cost of building them is a restricting factor in a developing society’s efforts to provide potable water for its people. Geosynthetics, represented by geomembranes, can provide water storage structures whose low cost in comparison to conventional concrete containments enable a greater number of reservoirs to be built for a given capital outlay. Membrane-Lined and Covered Reservoirs (MLCR), the subject of this paper, provide safe drinking water storage without compromising “First-World” requirements for durability, sanitary – requirements and ease of operation.
