What are the major sources of water loss?

the amount of water lost due to e.g. ruptures and leaks in the pipeline grid and reservoir overflows (also known as physical losses) unauthorised consumption, such as illegal tapping and meter inaccuracies (also known as apparent losses)

People also ask, how can water loss be controlled?

Some arid-climate plants are able to conserve water because of their reduced leaf size. Less leaf surface area results in reduced water loss through the epidermis. Small leaves have fewer stomata than larger leaves, and that adaptation also reduces water loss.

How are water loss distributions calculated?

Total water loss is calculated by subtracting the amount of water billed or consumed from the amount of water produced. It is important to differentiate between total water loss and leakage. Real losses comprise leakage from pipes, joints and fittings, from leaking reservoir walls, and from reservoir overflows.

Why leakages must be controlled?

All piped networks are subject to leaks and should be controlled. Due to the large time span between occurrence of underground leakage on such pipelines and the repair, water lost due to the underground leak-flows exceeds by far the water lost due to bursts from larger pipelines.

What is unaccounted for water?

Definition. Unaccounted-for water (UFW) represents the difference between "net production" (the volume of water delivered into a network) and "consumption" (the volume of water that can be accounted for by legitimate consumption, whether metered or not).
