Improving Tubewell Irrigation System Performance
Publication: Journal of Irrigation and Drainage Engineering
Volume 113, Issue 3
Abstract
Results of a field investigation on 10 selected deep tubewell irrigation systems in Bangladesh are presented. Development and application of a service area model to predict the impact of various improvement options are also discussed. The majority of the deep tubewells in the study are found to be severely underused in both the duration and efficiency of pump operation. The impact of each improvement alternative on service area expansion, as predicted by the model, varies among the tubewell systems. Increasing the pump operating hours is found to be the most effective measure for expanding the service areas of most study systems. Data used in the model application and economic analysis were obtained from field studies, technical papers, previous study reports, and judicious assumptions. Further verification of the model and updating of the conclusions may be needed. However, the model can be a useful tool in formulating successful service area development programs.
