Life depends on water. Water is also a limited resource. In many densely populated countries up to 30-40 % of the distributed water is lost. Leakages and inadequately maintained distribution systems are in the long term costly. Water is increasingly becoming a commodity. This makes non-revenue water even more important.
Water is not just about quantities it is also about quality. Knowledge is the key to improve the performance of a water supply system and it is available. The demand for more and cleaner water increase as urbanisation develops. To meet these demands modern technology and methods are required especially as the effects of climate changes become more pronounced.
Modelling and mapping of the systems is instrumental in providing the basis for planning ahead and implementing the right decisions. Analysing and mapping the system is the first important step. The next is to understand, how it functions and where to set it.
Combing on-line measurements of water quality and discharging with dynamic models which address all the relevant issues provides the understanding of how the system functions. It is this understanding which helps demands to be accommodated.
DHI technology and methods enable authorities, designers and operators to address entire distribution systems, pinpoint leakages and operate more efficiently in order to meet demands.
