An effect of groundwater quality on wells design in south Khartoum

الملخص EN

This study has been carried out in the area located in the south of Khartoum city and some parts of Gezira state, which is situated between latitudes 15.251 N, 15.567 N, and 32.502 E, 32.922 E.

The main objective of this research is to detect the effect of water quality on wells design, productivity, and sustainability.

The groundwater in the study area occurs mainly in the Nubian sandstone and Gezira formations, in the porous parts, and can be separated into two aquifers: the upper aquifer zone and the lower aquifer zone, which are separated by thick layers of mudstone of different thicknesses, especially in the industry area (soba).

For the purpose of this study, samples were collected from nine water wells and analyzed chemically and through a sieve analysis te&.

The testing results revealed that the south Khartoum basin has been polluted and has salinity in the upper zones with fit groundwater in the lower aquifer.

As for the results of the sieve analysis, it was shown that the lower part of the aquifer has a very good gradient.

The result of the study achieved the proper water well design for the basin and will be of good assistance to designers and decisionmakers for future water projects.

This &udy was conducted in the period between (12/05/2021 to 05.09.2022).
