The empirical method for the determination of apparent water losses, using the assessment of consumption patterns and the laboratory testing of water meters, is compared against alternative methods of comparative billing and meter change analyses for one of the largest water utilities in South Africa.

Optimal meter selection
The accuracy curve and envelope of a new water meter is governed by the type of water meter and relevant standards. Water demand patterns vary with time, period, seasons, consumers and combinations of these factors.
National Pricing Strategy for water use Charges
This strategy seeks to facilitate reform in the sector as well to provide transparency and predictability to water users on how water will be priced.
In Situ Calibration of Large Water Meters
The Water Research Commission (WRC) appointed Stewart Scott (CE) Inc. to undertake research to establish a flow reference standard for the cost effective in situ calibration of large water meters required for water audits and other test purposes.
Assessing Non-Revenue Water and its Components: A Practical Approach
IWA Task Forces recently produced an international ‘best practice’ standard approach for Water Balance calculations, with definitions of all terms involved, as the essential first step in practical management of water losses.
Introduction to Operation and Maintenance of Water Distribution Systems
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.
Guideline for reducing water losses
Many municipalities struggle to appreciate the necessity and benefits of dealing with water losses in their reticulation systems. Council officials will often debate at length over a budget allocation of a few thousand Rand when a road leak will run unattended for weeks if not months which can easily run up a bill of hundreds of thousands of Rand.
Municipal-Invoices in South Africa
The tax invoices or bills that municipalities send out to consumers on a monthly basis are a key interface between local government and citizens.
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.
