Worldwide, demand for water is rising and resources are diminishing. Water lost from distribution networks, or used to excess, for whatever reason, is a loss of a valuable resource. Controlling and managing such losses is therefore an integral part of water supply operations - to increase company efficiency, to maximise income, and to reduce the need for further resource development.  

Although there is technology and equipment available for addressing the ‘real’ losses, such as bursts and leakage from the pipe network, there are many other causes of losses. These are the ‘apparent’ losses, which can be influenced by the policies and practices under which a company operates, and which, in some cases, are as significant in terms of volume of lost water, as ‘real’ losses. However, these losses can be more difficult to quantify and control.

Utilities and customers are often unaware that they are using excessive or wasteful quantities of water. Here the problem is a lack of awareness of the policies, the water conservation programmes, and the water-restricting devices which can be introduced to help reduce customer demand.  

One of the major challenges facing a water utility is the high level of water losses both through physical or infra-structural losses and commercial losses. The losses calculated as the difference between the amount of water put into the network and the billed volume, known as NRW (Non-Revenue Water), needs to be kept at an optimal minimum for the utility to be efficient and sustainable
