Water Loss Management Summary Sheets: 3. Sectorising and Step Testing

Sectorising is the process of splitting a large water reticulation system into smaller zones which can be individually monitored to help in the identification of water losses and other water related problems. The process of sectorising is well known as a critical element of any water loss reduction programme and has long been regarded as the starting point of any comprehensive water demand management strategy.

Water Loss Management Summary Sheets: 2. Pressure Management

While managing water pressures in a supply area is not simple and there are a great many issues to consider, the common factor in every system is the fact that leakage is driven by pressure and if the pressure is increased, the leakage will also increase. If the water pressure in a system can be reduced, even for a short period during times of low demand, the water leakage from the system will be reduced. Pressure has been recognised as the single most important issue to be considered when trying to reduce leakage from a water reticulation system.

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.

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.

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.
