How to minimise water loss with sensors

Water utilities in the USA lose on average 16% of their water through leaking pipelines, thus never reaching their customers. Imagine Coca Cola or PepsiCo losing 16% of their product between leaving the factory and reaching their customers. And not just over one year, but many years in a row! Do you think they would still exist today?

Water loss is a waste of valuable resources and negatively impacts cost recovery of water services. Such water loss is unacceptable.

Sensor technologies which enable rapid detection of leaks help toimprove insight into the state of underground water infrastructure and support the prioritisation of pipe renewal and replacement. Sensors help to define a viable business case, so that investments result in maximum benefits for both the utility and its customers.

Showcase

Event detection in the distribution network and stakeholder involvement in action programmes

Drinking Water Utility A in the USA uses its online sensors for a wide variety of reasons, including the understanding of hydrodynamics and water quality and trouble shooting. Online sensors for e.g. conductivity are very effective at understanding water movements and mixing in a distribution system. When issues arise, online water quality data is useful in diagnosing the problems and in developing options for resolution.

The combination of grab samples and online monitoring helped identify areas of low usage/flow and oversized mains in the distribution system. DW-A was able to demonstrate significant detection of water quality issues with online sensor data.
