are in agreement with consumption figures for the Valley Trust area.<br />

An (overallJ bimodal daily water demand pattern is generally evident<br />

at water sources in rural and peri-urban KwaZulu, with peaks in the<br />

early morning and early-mid afternoon (where water is available some<br />

distance from the household). An average <strong>of</strong> three water collecting<br />

trips per day is undertaken by rural and peri-urban households, which<br />

may involve up to three hours (or more) in total. Longer periods <strong>of</strong><br />

daylight result in withdrawals beginning earlier and ending later inthe<br />

day. Water is not fetched at night. Of the per capita consumption<br />

<strong>of</strong> 15,6 i day-1, probably up to 5 i day-1 is used for cooking and<br />

food preparation, with up to 8 i day-1 being used for all washing<br />

purposes (bearing in mind the reuse <strong>of</strong> water). The balance is used<br />

for drinking needs. In terms <strong>of</strong> drought planning, a minimum supply<br />

<strong>of</strong> 15 i capita- 1 day-1 at a 100% assurance level (for all<br />

requirements) has been suggested for rural households (Maaren,<br />

1993)*. The World Health Organization recommended a design<br />

minimum <strong>of</strong> 50 i capita- 1 day-1 with a (reasonable access) distance<br />

to a standpipe <strong>of</strong> 200 m in urban areas. In the Transkei, a design<br />

criterion <strong>of</strong> 35 - 50 i capita- 1 day-1 was adopted for reticulated<br />

supplies in rural villages (Kruger, 1982 - above). Feachem et al<br />

(1978 - above) recommended a design supply <strong>of</strong> 30 i capita- 1 day-1<br />

for rural areas in Lesotho, which would apply for a decade. Alcock<br />

(1984)** suggested a design consumption <strong>of</strong> 25 i capita- 1 day-1<br />

for the Inadi Ward, for the period 1982 - 1992.<br />

Few data are available on the number <strong>of</strong> households or individuals<br />

usually dependent on a given external water source in rural and periurban<br />

KwaZulu. Alcock (1987 and 1989 - above) recorded the<br />

following dependency ratios (including standpipes and kiosks in the<br />

Durban Functional Region);<br />
