Design of rain water harvesting system from a rock catchment : a case study of Nyasigala Village-Tororo District.

Abstract

Water is life and agricultural production, unfortunately water is unevenly distributed across the globe as some areas receive-it in abundance while others get less than inadequate. In the arid and semi-arid regions of the world, rainwater harvesting was necessitated to buffer the acute shortages and scarcity. Uganda Government's commitment to providing clean water to its population, it faces severe constraints due to shortage of funds for development and the cost of maintaining existing water supply projects Clean water prevents the occurrence of certain diseases and therefore helps in keeping man healthy and enables him to perform his, day to day activities. However, this can only be realized if the clean water is available and conveniently reached by man. The potential benefits of rainwater harvesting include the availability of relatively clean water close at hand and the reduction in time arid labor far fetching it This project is aimed at designing a rock catchment rainwater harvesting, system that would help in supplementing the water demand for the locals Tororo, Nyasigala village were the rock catchment is located. The project is also focused on minimizing the cost through appropriate planning and designing of a rock catchment run-off water harvesting system coupled with the use of available storage technologies and local materials within the reach of the local communities The field data will be collected through observations, physical measurements, sample acquisition and use of existing records on the. study area, the project will analyse rainfall data and population data for humans. The analysis involved population projection, calculation of the catchment area, sizing of the conveyance system as well as sizing and design of the tank in accordance with the available run off and the demand
