Welcome to Farley Water Consulting

More than 30% of the world's drinking water is lost from urban water systems before it reaches consumers.

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.

Farley Water Consulting offers international water utilities and organisations specialist services for Non-Revenue Water Management - consulting, advisory, project monitoring and training services, tailored to each utility’s specific needs:
