Water Distribution Network to Address Uncertainty

Shrinking population in Japan and the associated attempt for amalgamation of small water supplies are two of the phenomena whose long-term impact to water service is still uncertain. To better prepare for these uncertainties, however, water utilities are now required to replace, downsize and even redesign distribution network for more efficient operation and energy use.
JWRC has been coordinating a program called "Rainbows" since 2014 in order to propose an effective method of redesigning existing water distribution network. Consisted of 18 water utilities, 19 private companies and 6 academics, the researchers have been working on various issues, including a systematic method of redesigning pipelines, putting together telling examples of efficient network renewal, how to downsize for demand reduction adjustment, and smart meter testing to examine their effectiveness.
JWRC will issue the final report in 2017.

Smart Water Metering

JWRC is studying benefits of smart metering and challenges for its wider adoption in Japan with a group of progressive water utilities that are engaged in intelligent metering or planning to do so.
