Geotechnical Investigation for appropriate excreta disposal system in riverine areas was piloted in Uta Ewa in Ikot Abasi Local Government Area and Ibaka in Mbo Local Government Area of Akwa Ibom State. Soils in both communities were characterized by high water levels and poor drainage because of nearness to water bodies. Within the depths of 1.0m and 2.0m, the underlying soil material tested was classified as ML representing organic silt and very fine sandy clay. Construction of septic tank/soak away pit is therefore not possible in these areas but would require some improvement to enable it give satisfactory support to the appropriate latrine facility.
