Water, the most valuable resource
Loss of water is something that an arid country such as South Africa can ill afford.
Municipalities are increasingly urged to find ways and methodologies to counter
the effects of the climate and usage, and to enhance water recycling and water
treatment technologies. In the May/June edition of Water, Sewage and Effluent,
Part 1 of the Report to the Water Research Commission addressed the aims,
methodology, and outcome and findings.

reserves of water in some of
Africa’s driest areas — including
the Sahara Desert — and scientists’
assurances that these huge reserves
could provide a buffer against the
effects of climate change for years to
come, the continent is, in most parts, a
desert by definition. We can no longer

resource. The second extract from the
Water Research Commission Report

Guidelines
Monitoring systems are proposed
for the three key components of a
potable reuse plant, namely raw

water monitoring, operational and
control monitoring, and compliance
monitoring. The monitoring makes
provision for early detection of
deteriorating incoming raw water
quality, rapid changes in the raw water
quality, maintenance of treatment

of operational alert levels for the
