SAPS College is located on a large, campus-like facility in Pretoria comprising offices, housing, hostels, flats, a hospital and various sports facilities. It is the only police college in South Africa with an influx of new recruits arriving in January of each year to commence with their police training.
Water is supplied to the facility from the City Of Tshwane and is routed via internal reservoirs to the various facilities within this sprawling property.
Due to the geographical layout and location of the property, large variations in pressure occur at various points. These pressure variations can create pipe bursts particularly at weak points in the aging water infrastructure.
In order to limit these incidents, Reonet developed optimum and discrete pressure zones and discrete metering zones to facilitate regular step testing and minimum night flow analysis. As a result a priority list of zones where large scale leaks and losses occurred could be prepared and technical teams were able to systematically work through each of these zones, conducting specialised leak detection and repair, pressure management, and identifying waste and opportunities to make use of alternative water sources such as boreholes, grey-water recycling and rain water harvesting.
Another important aspect of this project was the comprehensive valve audit and valve replacement programme. Poorly maintained valves were no longer operational and needed to be replaced before infrastructure maintenance and repairs could take place.
Digital modelling of the water network also enabled Reonet to do critical analysis and effectively manage the water supply system throughout this site.
Reonet has achieved an approximate 9% saving on water costs. Management on site have become more aware of water losses and water wastage and have been instrumental in achieving behavioural change on site.
