STUDY TO. IMPROVE OPERATION AND MAINTENANCE OF NAM HUAM IRRIGATION SYSTEM IN LAO PDR

Abstract

The Namhuam irrigation system is proposed be used to meet out the rising food demand for continuing increasing population growth. Namhuam irrigation area with 1500 ha, located at Nasaythong District may be developed with basic principle "Low cost and simple technology concept". In agricultural area, proper water management is a key factor for optimal crop production. The success of water management depends on the efficient operation of the infrastructure and also the economical maintenance of the system in order to maintain the capabilities in a good order. Operation activity should beplos 4y- well coordinated in order that the available water may be properly utilised to meet the needs of the water users. Maintenance objective are: 1. To keep the system in top operating condition at all times through proper maintenance. 2. To obtain the longest life and greater use of the system's facilities by providing adequate maintenance and replacements and also to ensure safety of the works. 3. To achieve the above two objectives at the lowest possible cost. In this dissertation, the study would cover both operation and maintenance of the infrastructure created for Namhuam irrigation system. It is hoped that this dissertation study will help in achieving better understanding of Namhuam irrigation system- and may suggest some appropriate measures and guide lines for adaptable strategies for optimal operation and maintenance. This would ensure better equity in distribution of water and also achieve high production levels.
