This study was conducted to evaluate the performance of an air tight local drip irrigation system. It evaluates the water distribution efficiency, considering the water quality and the duration of usage. The water distribution efficiency, water physicochemical analysis, soil analysis were determined for the drip irrigation system. All parameters were found to be below the level of concern. The procedures were based on taking measurement of emitter discharge along selected drip lines on a sub-main. Twenty water discharge were collected using sample containers results recorded. Results indicated that the uniformity of water application was 80% indicating that the emitter is good. The average discharge rates were 0.14 l/h, 0.16 l/h, 0.19 l/h, 0.20 l/h, 0.22 l/h, 0.24 l/h, 0.26l/h and 0.31 l/h respectively. The water distribution efficiencies at different air intakes are: 79.5%, 79.5%, 80%, 80% 79.5%, 79.5%, 79.5% and 79.5% respectively indicating good water application and was quite significant for the evaluation of the uniform distribution of water. The constructed drip irrigation system in this has shown that drip pipe network can be used for different plant with similar water requirement and spacing, this will save the cost of changing pipe network each time there is changes in crop with similar water requirement and spacing. In this research work the rate of discharge depends on the volume of air entering the system water tank. All the materials used in this construction are locally sourced materials.
