Water Energy Efficiencyimprovementin Eastern Province Of Sri Lanka

Abstract

Energy efficiency improvements at water facilities can significantly reduce the cost since the energy costs typically constitute about 25% to30% of the operations and maintenance cost. Thus this analysis is based on a collection of information from the water facilities of NWSDB Eastern province. This provides the information from January, 2013 to December, 2013 for the four regions namely Ampara, Akkaraipaththu, Batticaloa andTrincomalee in the Eastern Province. Bench mark analysis and Project Appraisal Committee reports were considered in planning, designing and implementation stages to minimize energy Usage. This will ensure the proper capital investment and future operational and maintenance cost. Also, this analysis will help NWSDB to investigate the energy saving techniques and to develop bench mark for each pump for the energy consumption per cubic meter of water. It can contribute to cost reduction and saving could be utilized for the development of the country in investing other development works and improve infrastructures.
