10. The program presented in the scope of work aims at completing the works for the construction of:
• 12 water wells tapping the Shallow Sand Aquifer (SSA) in the Greater Banjul area, at an estimated depth of 130 m to 150 m. Each well is designed to reach at least a rate of 100 m3/h with a minimum drilling diameter of 14 “¾.
• 4 water wells tapping the Deep Sand Aquifer (DSA) (Maastrichtian) including reconnaissance phase (1 pilot borehole) in the Greater Banjul area at an estimated depth of 450 m to 600 m. Each well is designed to reach a productivity ranging from 150 to 250 m3/h with a drilling diameter range between 11 “and 12 “¼.
A reconnaissance step will have to be implemented, since the geometry and nature of the aquifers are subject to uncertainties. The final depths of the boreholes and equipment will depend on the results of these reconnaissance steps. The drillings will be followed by the development of the well and a sequence of pumping tests.
