LCE were appointed, by NamWater, to carry out a detailed assessment of their water supply infrastructure in the north central part of Namibia. This study commenced with a physical condition assessment of the infrastructure components which included 1,359 km of pipelines, 37 pump stations, 139.6 km of canals, 4 dams and forebays, 48 reservoirs and 5 water treatment plants. Water consumption patterns for the project area were analysed and scheme water balances and loss estimations carried out. Following the preparation of water demand forecasts, a capacity assessment was conducted for each infrastructure component of each scheme in order to determine its sufficiency lifespan. Computerised modelling, using Bentley’s WaterCAD software package, of the water demands and the capacity of the various infrastructure components was also carried out as part of this sufficiency analysis. Proposals were then prepared to replace / upgrade all scheme components found to have insufficient capacity, with cost estimates attached to each proposal, and the project activities and results were detailed in report format for submission to NamWater.
