Monitoring Programmes
• Variety of Monitoring Programmes
– Rand Water
• Plant
• Point of Purchase
• Point of Sale
– Magalies Water
• Plant
• Point of Sale
– RWST (Kloof & Bospoort Plants)
• Plant
• Command Reservoir (Point of Sale)
– RLM (Service Provider)
• Storage & Distribution
• Point of Use
Incident Management
• Well managed by individual service providers
– To point of sale to RLM only.
– Service Provider reported failures but was unable
to follow up actively.
– Lag time often too great
– Source of the failure not easily able to be
determined
– Blended water can produce some surprising
anomalies
System Review
• Systems needed to be broken down into
smaller units so that DWQ failures could be
traceable.
• Marikana and Borehole Systems Ok
• Royal Bafokeng System
• Rustenburg Town System
• Vaalkop System

Conclusions
• Monitoring Programme must be risk informed
• Systems need to be a manageable size so that
the source of failures can be traced.
• Plants treated separately on the BDS
• Sample points need to be carefully selected
• Co-operation required between all role players
– Incident Management
– Avoid duplication of monitoring
– TAPS programme
