The NRW and the importance of more efficient water infrastructure management models
When achieving maximum sustainability in the water and sanitation sector has become a vital goal, it is interesting (and necessary) to investigate some concepts related to the management of the integral water cycle.

In this new DAGA blog post, we take a closer look at NRW.

What is the NRW?

NRW is the acronym for Non-Revenue Water and refers to the main indicator of the performance of a water supply system, within the framework of development in its areas of competence.

Conversely, the concept of Registered Water (RW) includes consumption by individuals (domestic, industrial, commercial and industrial), as well as by the public (irrigation of parks and gardens, supply to fire departments and supply to fountains).

Although, depending on the use to which the NRW is put, it can be expressed in different ways, it is mostly taken as a percentage of the total volume of water supplied. Of this total, the NRW represents the sum of water losses (apparent and real) and unauthorized consumption (measurement fraud, meter inaccuracies, etc.). 

Control of Unregistered Water

At the beginning of 2020, the National Commission of Markets and Competition (CNMC) published the "Study on urban water supply and sanitation services in Spain." Among many other interesting data, it reflected the percentage of NRW in the country's municipalities, which has fluctuated around 25% since 2007.

In addition, the CNMC pointed out that most of the NRW corresponded to actual losses recorded in the distribution network (leaks, breaks and breakdowns in the distribution network). The obvious solution - although complex in execution - is for the main players in the sector, the management companies, to focus their efforts on increasing the registration of recordable consumption and, consequently, to reduce non-recordable consumption.

As experts point out, reducing Non-Revenue Water by increasing Registered Water makes it possible to recover m3 of water at the sale price and, therefore, produces an increase in income. To achieve this, it is necessary to have meters at all water intakes, to detect the lack of meters to detect fraud. In addition, they add, there is a need to control the NRW directly through abatement. This increases the sustainability of the system and contributes to the fight against climate change.
