||Comprised of largely coarse-grained alluvial sands and gravels, which can reach up to 120 m thick. Recharge is high, coming both from direct rainfall infiltration and indirectly from river infiltration. Areas which are known to have particularly good potential include Libenge and the alluvial plain between the N’Djili River and Ngaliema Bay in Kinshasa (Partow 2011). Transmissivity values from borehole test pumping are often 10 to 200 m<sup>2</sup>/day, with borehole yields of 0.2 to 0.6 l/s (15 to 50 m<sup>3</sup>day).

||Variable - Low to High
 
 
||Away from the Cuvette Centrale and Oubangui areas, outcrops of unconsolidated sediments - including alluvium, laterite gravels, aeolian sands and other deposits - have variable aquifer properties, depending on their lithology, depositional history, thickness and lateral extent. Thick sediments dominated by sand and gravel can form highly productive aquifers, but finer grained and/or thinner sediments tend to form low to moderate productivity aquifers.
