Environmental Appraisal of Drainage System in Minna, Niger State, Nigeria

Abstract

Available records indicated that erosion and flood problems in Minna have assumed such frightening magnitude in terms of loss of lives and properties. This study is in response to the need to find solutions to major waste disposal methods in Minna. Various methods were used for the appraisal, among which were reconnaissance of the town, effect of rainfall on the erosion and flood of the town. Rainfall data were collected and street pictures showing blocked drainage paths and indiscriminate dumping of refuse to illustrate study areas. It was found that, drainage system of the town is grossly inadequate, with poor sanitary culture, improper layout of houses and moderately high rainfall depth, all contributing to the high rate of erosion and flood problems of the town. It is thus recommended that adequate measures be taken to reduce the problems of erosion, and the improper lying out of town be revisited.
