Several researchers have estimated the demand for water for basic living within Aboriginal communities. For those whose needs are only drinking, cooking and washing, demand is estimated to be 10-50 L/p/d (Gillies 1977, Walker 1980); for those communities with septic tanks or some sort of water carriage system forwaste disposal, the demand rises to 30-300L/p/d (Collin 1985, White 1977); and for those communities who, in addition to the previous requirements, make provision for water for gardening, the demand is 580-760 L/p/d (Collin 1985, WAWA 1986).
Table 8 Water Supply Level Guidelines A Minimum Supply Level (where water resources are very limited)
C Desirable Supply Level (where increased supply can be provided at reasonable cost) It is important to note that the three supply levels shown are essentially only convenient reference levels on a continuum.
