Energy-Cost Optimisation in Water-Supply System

Households as well as community water-supply systems for utilisation of underground aquifers are massive consumers of energy. Prevailing energy crisis and focus of the government on demand-side energy policies (i.e., energy conservation) in Pakistan raises need of using energy efficient techniques in almost every aspect of life. This paper analyses performance of community relative to household water-supply system in connection with efficient energy utilisation. Results suggest that total operational energy cost in case of community (centralised) water supply system is lower than the cost incurred under the household (individual) water pumping units. Besides, average fixed cost under community water supply system is three times less than that incurred under household water supply system
