For many cities, reducing NRW should be the first option to pursue when
addressing low service coverage levels and increased demand for piped water
supply. Expanding water networks without addressing water losses will only
lead to a cycle of waste and inefficiency. Also, a high rate of NRW is closely
related to poor energy efficiency, since water transported in networks is “loaded”
with energy through the distribution and treatment processes. Thus, energy
is lost along with the water. Therefore, reducing NRW is important to overall
efficiency and financial sustainability, since it provides additional revenues and
reduces costs.
