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.

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.

Monitoring and Evaluation Manual
Effective Monitoring and Evaluation is useful to the extent that it provides information to an effective management system and should ideally be part of a performance management system.
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.
Water demand management scheme: Drakenstein, South Africa
Over a period of approximately 12 years, Drakenstein Municipality lowered the non revenue water from over 33% to just under 11% and currently ranks amongst the best municipalities in South Africa with regards to water use efficiency.
Water Demand Management
This guide concentrates on highlighting the key issues in simple and straightforward terms in an attempt to explain what interventions can be undertaken in order to reduce water losses from municipal water supply networks and how best to implement them.

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.
