What on Earth is NRW?

Saturday, April 26th, 2008

Trust me, I never heard any kind of phrase such of that. NRW is stand for Non-revenue water, generally can be applied in water works industries. I was akin of knowing this when my client is NRW department of A Malaysian company, Syarikat Bekalan Air Selangor Berhad (SYABAS). I was a bit ashamed when I found out that I don’t really know what is NRW means. That means, I don’t know my client. LOL.

Non revenue water (NRW) is water that has been produced and is “lost” before it reaches the customer. Losses can be real losses (through leaks, sometimes also referred to as physical losses) or apparent losses (for example through theft or metering inaccuracies). High levels of NRW are detrimental to the financial viability of water utilities, as well to the quality of water itself. NRW is typically measured as the volume of water “lost” as a share of net water produced. However, it is sometimes also expressed as the volume of water “lost” per km of water distribution network per day.
