Home Glasson Partners envisaged the phased introduction of three
levels of service (up to the year 2025), with respect to black formal
and informal township dwellings in the old Umgeni Water supply area
(including Clermont). The relevant data (allowing for up to 20%
losses within the supply system) are presented below:
Service Black formal dwellings with Black informal dwellings with
level waterborne sanitation in situ sanitation
1 Full service 75 t capita- 1 day·1 25 t capita· 1 day·1
(standpipes at 200 m intervals)
2 Full service 120 t capita· 1 day" 50 t capita·, day"
(one standpipe per plotl
3 Full service 75 - 235 t capita· 1 50 t capita" day"
day" (dependingon rising income) (one standpipe per plot)

Water, Pietermaritzburg, various pages. (The authors observed that under
certain scenario conditions - see (iv) below - a design consumption of 120 f
capita- 1 day-1 (full service level 2) might constitute an overestimate, where
a more realistic figure would be of the order of 80·95 t capita· 1 day·1 with
regard to expected standards of living. However, if high economic
prosperity is evident in the future (after 2005), then a design consumption
of 120 t capita- 1 day·1 would not meet the actual demand resulting from
a considerable increase in living standards. A minimum service of 50 t
capita· 1 day·1 for formal dwellings and 25 t capita- 1 day·1 for informal
dwellings was suggested for the old Umgeni Water supply area. This was
regarded as the most basic requirement which should be maintained, for
example, during drought periods).
(iv) A few water demand projections for NatallKwaZulu (published prior
to the 1994 general elections) made reference to political and socioeconomic
scenarios, as primary planning factors. Home Glasson
Partners of Durban, for instance, referred to a "status quo" scenario,
an "emergent trends" scenario and a "high road" scenario'. Both
industrial and domestic water requirements are important in scenario
planning. In the latter case, special emphasis was placed on the
domestic water needs of the rapidly urbanizing black population,
mainly in the Durban-Pietermaritzburg Metropolitan Area. Despite
obvious changes following the general elections, scenario planning
(as a technique) is still relevant.
