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.

Benchmarking leakage from water reticulation systems in South Africa 2004
The BENCHLEAK software was developed through the Water Research Commission to provide a simple yet pragmatic approach to the evaluation of leakage from potable water distribution systems. The model is used to assist water utilities to evaluate the levels of leakage and non-revenue water in their water distribution system.
Municipal Water Demand Management Balanced Scorecard Model
Balanced Scorecards have been used for many years to assess and monitor complex situations which involve a wide range of functions, many of which cannot be assessed or quantified in a normal manner. It is ideally suited to multi-disciplinary activities such as the operation and management of a water utility.
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.
Aqualite Water Balance User Guide
AquaLite has been designed to provide a pragmatic and straight-forward approach to a relatively complex issue and its design is based on the experience of many specialists dealing with such issues on a daily basis in many parts of the world.
Benchmarking of Leakage from Water Reticulation Systems in South Africa 2005
The BENCHLEAK model was developed to evaluate levels of leakage and non-revenue water in potable water distribution systems. The first study involved developing the model with a limited budget for checking the various data sets used to test the model. The main objective of the follow-on study was therefore to use the model to evaluate the levels of leakage in approximately 30 water utilities throughout South Africa.
Non-Revenue Water in South Africa
Municipal water use in South Africa has been under investigation for many years and the Department of Water Affairs and Forestry has been trying to establish the levels of wastage from all water supply systems countrywide.
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.
Presmac: Pressure Management Program
The PRESMAC pressure management model is used to assess the likely savings (in monetary terms) of various pressure reduction options (fixed-outlet and time –modulated PRV’s) in a selected zone metered area.
Sanflow User Guide
The SANFLOW model is designed to help water suppliers to determine the level of leakage in a particular zone metered area (ZMA) from the analysis of recorded minimum night flows.
