For actually more of 18,160 small rural indigenous communities (SRIC) in Chiapas there is not drinking water. In order to contribute a given solution to scarcity of drinking water in the SRIC, The Autonomous University of Chiapas (UNACH in its Spanish acronym) and Mexican Institute of Water Technology (IMTA in its Spanish acronym) designed and constructed in 1999 the Rain Water Harvesting (RWH) in Yalentay municipality of Zinacantan in Chiapas, Mexico. The scientific and technical contributions of RWH are: The design guarantee the water quality for a prolonged time of storage avoiding the photosynthesis inside the system;Not emitted greenhouse gasses because it doesn’t need any kind of fossil fuels;Not produces anything kind of damage to the environment;It has to be inexpensive, using in its construction manpower and materials from de region;Store the maximum quantity of water in the minimum space. The RWH has increased the standard of living of the habitants from Yalentay and improving their health conditions.展开更多
