A water distribution system acts as a conduit to reliably transport adequate quantities of safe drinking water to consumers. To achieve this, the system needs to work as intended and maintain a physical barrier between the water inside the network and the external environment.

The Status and Use of Drinking Water
This report is the result of a project carried out to explore the status of water efficient devices in the domestic and commercial environments in South Africa.
Introduction to Integrated Water Meter Management
Water metering is particularly important for municipalities since it forms the basis for much of their income through the sale of water to their consumers.
The State of Non-Revenue Water in South Africa
The Non-Revenue Water for municipal water use in South Africa is estimated to be 36.8%. While it is clear that there is significant room for improvement, it is also important to recognize that the South African figure is in line with the World average value of 36.6%.
Municipal Water Demand Management Balanced Scorecard Model
Balanced Scorecards have been used for many years to assess and monitor complex situations which involve a wide range of functions, many of which cannot be assessed or quantified in a normal manner. It is ideally suited to multi-disciplinary activities such as the operation and management of a water utility.
Apparent Water Losses Related to Municipal Metering in SA
Apparent losses consist of water that is delivered to consumers but look like losses to a municipality. It consists of two main components: water meter under-registration and unauthorized consumption. Meter reading and data errors may also contribute to apparent losses.
A Guide to the Control of Water Losses in Pipe Networks
Water lost from a water supply distribution network can account for a considerable percentage of the total volume of water supplied. As this loss is paid for by consumers, a reduction in the amount of water lost could lead to a decrease in water tariffs, smaller pipe sizes and reduced water purification capacity and a delay in the need for increased storage.

Guidelines for Water Balance
The IWA developed the standard water balance to benchmark and evaluate the performance of water distribution systems and is being promoted across the world as best practice.
