Ekurhuleni Metropolitan Municipality (EMM) is the industrial heartland of South Africa and supplies approximately 314 000 000m3 /year to 800 000 households. Metering of the top consumers in EMM had not been a high priority for many years with the result that many of the supply meters to existing consumers were either broken or unreliable with non revenue water estimated to be around 50% of the water being used.

Reducing water losses in Municipalities: Key issues and pointers to implementation
Saving water and water demand management (WDM) in general can be quite confusing to a municipality wishing to embark on some form of water loss reduction activities. A lot of work has taken place in South African and internationally to support water loss reduction in order to save money.

Experiences with advanced water metering in South Africa
Advanced water metering is part of a larger movement towards smart networks and intelligent infrastructure. In high-income countries, advanced metering technology is generally focused on the need to obtain meter readings without human intervention. However, in South Africa and other developing countries, advanced water metering is driven by the need to provide services to previously unserved communities and deal with the problems caused by rapid urbanisation.
Assessment of apparent losses due to meter inaccuracy – a comparative approach
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.
Economic Model for Leakage Management for Water Suppliers in South Africa (ECONOLEAK)
The ECONOLEAK mode is aimed specifically at determining when a water supplier should invest in active leakage control for a specific zone metered area.
The State of Water Metering in South Africa
High levels of Non-Revenue Water (NRW) are a major challenge for municipalities and utilities worldwide
Meter Management
Water metering is an excellent application of the principle to measure, is to know, and knowledge of what is happening with the water in a distribution system is the key to properly managing this resource.
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.
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.
