Sustainability of Groundwater for Domestic Uses in Rural Communities of Kogi State, Nigeria
Journal Title: Saudi Journal of Engineering and Technology - Year 2017, Vol 2, Issue 9
Abstract
Abstract:Groundwater is a natural resource that is of immense importance to life and its characteristics are greatly determined by the properties of the immediate geologic formations. Generally, the development of groundwater resource involves three main stages: exploration, evaluation and exploitation. This study focuses on the evaluation stage, which generally encompasses measurement of hydrologic parameters, and estimation of aquifer yield. The analysis of pumping test data collected for 17 wells spread across Kogi state was used to determine the hydraulic parameters of the aquifers within the study area. Transmissivity values ranged from 0.751 – 8.92 m2/day, hydraulic conductivity ranged from 0.0867–1.33 m/day, pumping rates ranged from 1.13 – 8 l/s, while the borehole depths ranged from 11.3 – 202 m. Groundwater maps of the hydraulic parameters were also developed for the study area. These results show that the aquifers within the study area can provide between 5000 to 40,000 litres of water per day. The aquifers can therefore serve as sustainable and dependable sources of water all year round with sufficient water to meet the domestic needs in many small rural communities of Kogi state.
