3-Water Balance
In order to understand NRW quantitatively and qualitatively is essential to know about Water balance as to how much water is supplied and where it ends up. This section highlights the various ways in water is consumed and invoiced. This understanding will enable the participant to distinguish between various types of consumption and losses.
One definition of Non-Revenue Water (NRW) is directed to identify the difference between the cubic meters of water that are distributed into the water distribution network and the cubic meters that are invoiced with the customer. This definition leads to see NRW as a water balance that takes real losses (physical losses, such as leakages), apparent losses (commercial losses, such as illegal water connections) and unbilled authorized consumption (such as water used by fire fighters, or for the watering of public parks) into account.
