It takes a lot of energy to pump and treat water for urban residents and industry – between 2 to 3 percent of the world’s energy consumption, to be exact. As a result, clean water is often inaccessible in energy-poor countries. Our Watergy program has helped improve water sanitation and delivery services in more than 100 cities worldwide.
Watergy efficiency measures reap many rewards, such as immediate improvements in water service, increased water delivery, reduced water and energy consumption, greater revenue for system upgrades and new customer connections. Moreover, the improvements have rapid rates of return spanning from a few months to three years.
While opportunities for energy efficiency improvements abound throughout all stages of a water supply system, the most promising areas for intervention are improving the pumping system, managing leaks, automating system operations, and regular monitoring (preferably including metering of end use).
