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.

Water Loss Management Summary Sheets: 1. Importance of Logging
Flow and pressure logging is an essential element of any comprehensive water loss reduction programme for all municipalities.
Reducing water losses in a large distribution network City of Johannesburg South Africa
Reducing water losses is a priority for Johannesburg Water. These are made up of leakages on transmission and distribution mains, reservoir and storage overflows and leakages on service connections.
Pressure management in municipalities: Sebokeng and Evaton, South Africa
Maintenance of water supply networks in many low income urban areas in South Africa has been neglected over the last 30 years and has resulted in serious service delivery problems and wastage of water.
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.

Sanflow
The SANFLOW program represents the first of several programs that are being developed through the WRC in order to assist water suppliers to manage and reduce their levels of unaccounted-for water.
Pressure Management Program (PRESMAC)
The PRESMAC model represents one of several models that are being developed through the WRC in order to assist water suppliers to manage and reduce their levels of unaccounted-for water.
Hour-Day
The Hour-Day Factor is simply a factor that can be applied to a reduction (or increase) in the pressure dependent flow occurring at the hour of Minimum Night Flow to provide an indication of the total daily saving (or increase) in pressure dependent flow that can be expected over the whole 24-hour period.
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.
