Understanding of the local geology is the starting point for the understanding of groundwater occurrence because it’s the presence of permeable and impermeable layers in the subsurface that control how and where groundwater will flow. Knowledge of meteorology and hydrology is necessary to investigate groundwater, rainfall and surface water relationship. Chemical knowledge is used to investigate groundwater quality. Drilling boreholes and pumping water out of aquifers require appropriate skills.

WAD provides the following services:

• Desktop study of site geology and hydrogeology.
• Groundwater investigations for Environmental Impact Assessment (EIA), Environmental Management Program (EMP).
• Sitting of water supply borehole, drilling supervision and quality control and borehole logs.
• Hydrogeological census for baseline information.
• Geological and hydrogeological site characterisation as part of mine dewatering system design.
• Groundwater monitoring and management.
• Aquifer testing to determine aquifer parameters, borehole efficiency, borehole sustainable yield and its abstraction schedules.
• Selection of a appropriate pump size to be installed in the borehole based on pumping tests results and water reticulation design.
• Supervision of borehole pump installation (electrical and solar pumps).
• Development of numerical groundwater flow model for mine dewatering and for groundwater management including water balance.

**** WAD, we provide cost effective and sustainable services to our clients, and are responsible for making sure that we have located the groundwater and that its quantity and quality are assessed ****
