| dc.description.abstract | Groundwater is a rich resource that contributes significantly to Uganda's entire annual water
supply. Local governments in Uganda, particularly in Mukono, seek to harness the substantial
groundwater resources in the district to attain the needed Safe Water Coverage in various
sections of the district. This initiative primarily entails the construction of Deep Boreholes at
diverse locations in the different sub-counties appropriate for groundwater abstraction.
However, this initiative is not a sustainable solution for proper utilisation of the groundwater
resources in the district. This is because having numerous deep boreholes in the same aquifer
creates considerable drawdowns in the water table, reducing borehole yield. Furthermore, the
expense of creating these deep bore holes is significant and will continue to increase as the
depth of the water table drops. Therefore, the study aimed at developing an integrated map that
can be used in the development of a Gravity Flow System in Kyampisi, Nama and Goma
division sub-counties in Mukono district that can be used in substitute of the construction of
numerous Deep Borehole. This involved hydrogeological mapping of the aquifers in the subcounties
of Kyampisi, Nama and Goma Division using suitable criteria such as soil types, land
use, elevation, geology, rainfall density, drainage and borehole yield. These criteria were
analysed in ArcGIS due to its high ability to manage and analyse various data. In addition, the
AHP (Analytical Hierarchy Process) method was used to derive the weightings of criteria,
through a matrix of pairwise comparison to integrate the different criteria. This enabled the
development of an integrated map using the weighted overlay in ArcGIS that can be studied to
determine the potential groundwater zones with maximum yield and identify production wells
that can be aggregated to be used in developing a Gravity flow scheme for the sub-counties . | en_US |
