Energy Efficiency in the Water Distribution System

Qory Constantya

Abstract: PDAM is one of the drinking water providers that is responsible for providing water to the community. Electricity or energy costs that must be paid by PDAM are around 30 % of all operational costs, of which about 80 % are for electricity or costs for treatment plants and distribution, especially for pumping cost. Energy efficiency efforts can be done by first identifying the factors that influence energy consumption and then selecting the appropriate technology according to the site conditions. Water supply system, water demand profile and leakage rate are main factor that affect the energy consumption of the drinking water distribution system. Some things that are considered in determining the energy efficiency technology to be used are the water supply network, the service area topography, the energy efficiency technology that has been used and others. Asset management can also play a role in the analysis of technology requirements for energy efficiency. The technology in this paper implies pressure regulation for energy efficiency such as pump scheduling, tank, variable speed pump, pressure reducing valve, harmonic oscillator tank and pump as turbine.
