A detailed Water Conservation & Demand Management Plan is a powerful tool in the effort to reduce the daily water demand and consumption. See Figure 11. In practice, however, the demand is often monitored at supply points where the measurements include leakage, as well as the quantities used to refill the balancing tanks that may exist in the system. It can also be attributed to low levels of investment in water resources services and the inability to cope with the growing demand for water in response to population growth and economic development (Mwanza 2003). OUTH AFRICA IS CONSIDERED TO BE A WATER SCARCE COUNTRY and, if the current rate of water usage continues, demand is likely to exceed supply at some point in the not-too-distant future. If water use results in evaporation, incorporation into a product, or diversion out of a water basin, it is considered consumptive use. The deficit/surplus analysis creates three values, Water Allocation Monthly Average Daily Demand (MADD), Water Allocation Annual Average Daily Demand (AADD), and Firm Capacity (FC). Worthington * Griffith University September 2010 ABSTRACT Unlike the modelling of residential water demand, very little recent empirical work has concerned the estimation of commercial and industrial water demand.
