In this paper is showed the design of a system of drinking water supply for small rural communities trough rainfall collection-treatment plant. The design of the developed treatment plant considers a consumption of 60 1/h/d. In this work the following characteristics have been retained as the representatives for a rural comunity: £ 200 inhabitants; lack of potable water and electrical energy; to count on the possibility of supplying themselves of surface water under specific topographical conditions that they diminish the requirements of energy in the purification process. The rainwater harvesting represents a frequent scene in Latin America, and the proposed process of purification considers devices of low cost and easily operation.In this paper is showed the design of a system of drinking water supply for small rural communities trough rainfall collection-treatment plant.
