Non-Revenue Water (NRW)
In water distribution networks, non-revenue water (NRW) is water that is produced but lost or becomes unaccounted for before it reaches the consumer. The losses are mainly associated with leakages identified as real losses or physical losses. Still, it can also be caused by commercial losses (apparent losses) associated with water theft or metering inaccuracies. NRW typically represented with a water balance table, as shown below, which described each contributing factor of NRW.
Any effort to tackle NRW problems looks into each of these factors in detail and solves them one by one. However, identifying the priority actions in tackling NRW is a common challenge for water operators. That is why Ocned, in partnership with Niras, is a strong advocate of a holistic approach to tackling NRW problems. By adopting the LEAKman guide for a holistic approach to NRW reduction, Ocned is committed to delivering NRW solutions to help water operators bring down the NRW level and consistently manage it in the long term.
The LEAKman approach has carefully identified priority actions which are strategized in 4 phases. Each action was thoughtfully placed in the specific phase based on the worldwide experiences of each members of LEAKman's consortium which comprises of equipment specialists, water operators, academician, and water consultants.
As part of our service, Ocned offer a full NRW consultancy service to guide water operators in their NRW reduction journey as well as specific service such as the following:
