Water Audits


The challenge in any water utility is to define where the water losses are occurring (leakage, commercial losses and NRW) and then to address ways of reducing them. 

There are always improvements that can be made – and there are always solutions that can be put in place. Some of these are low-cost or no-cost (for example, policy and operational changes). However, most come at a cost (additional technology, extra manpower) but are usually cost-effective.

A water audit gives a utility the knowledge to address these solutions – by providing a thorough review of management policies and practices, the network operational practices, and the current utility infrastructure condition, network records and status of active leakage control.  

The information gained allows the utility to begin developing a strategy to reduce NRW management, to recommend management and staffing changes as necessary, and other institutional strengthening such as skills development and training.


A Water Audit lets a water utility understand where water is being taken in each part of the network and to prioritise remedial actions - 'to minimise leakage and maximise income'.  The audit is a stepwise process - one of the first steps is to conduct a 'Water Balance' to understand where water is going in each part of the network.
