Energy Efficiency in the Water Supply and Sanitation

Energy efficiency improvements can benefit the WS&S sector in numerous ways. One of the promising public sector areas for energy efficiency improvement in Brazil is the water supply and sanitation (WS&S) sector. Energy consumption (mainly electricity for pumping) is typically the largest variable cost item for a water utility after personnel.
