Water Demand Management (WDM) is a fundamental part of an integrated approach to sustainable management of the water sector, particularly important in an arid country such as Namibia. "WDM involves measures that improve efficiency by reducing water use or altering patterns of water use after abstraction" (Beecher, 1995). Within the Namibian context the WDM strategy attempts to improve cost recovery, the management and maintenance of infrastructure and the reduction of inefficient consumer demand to reduce the pressure and reliance on conventional water resources and infrastructure. By reducing demand, through a variety of approaches, Water Demand Management (WDM) provides an equivalent outcome to supply augmentation. This, in turn, results in a net financial benefit to the supplier as well as its customers and benefits to the environment.
