Background• 2001: Regulations under Section 9 promulgated.• 2003: SFWS included DWQ as one of the
performance areas the sector would monitor.• 2004/2005: The 1st DWQ Framework is drafted.• 2005: DELMAS• 2006/2007: DWQ Framework Revised to improve
content. And to ensure that the document remains applicable to the South African DWQ Challenge.

DWQ Regulatory ObjectivesDWQ Regulatory Objectives• To facilitate the improvement in DWQM by ensuring that:
– All Water Services Authorities (WSA’s) are fulfilling their obligatory DWQ monitoring and info management functions;
– Process Control is improved by means of sustainable and continued training of treatment plant Process Controllers and Operators;
– Water Safety & Security Plans are in place and implemented;• The public have meaningful access to DWQ info at reasonable
frequencies;• by implementation of measures/mechanisms that will ensure
consumers trust the quality of drinking water in their respective areas of supply by 2009, and
• Ensure that all DWQ failures are dealt with according to legislative requirements.
• Mission Statement:• We are committed to enhancing the quality of life of all South Africans
by continuously improving the quality of drinking water to ensure that its safety is not compromised.

DWQM Self-Assessment for WSA Management
1. Are we giving sufficient attention to DWQM at our WSA/WSI?
2. Are we complying with all legislation in this regard?3. Are we confident that infants, elderly,& other immuno-
compromised in our constituency are not at risk when consuming tap water from our reticulation system?
4. Are we confident that our monitoring programmes are yielding credible data on the quality of our tap water.
5. Are those responsible for the treatment and reticulation of drinking water sufficiently capacitated?
6. Do you prefer tap water to bottled water & filtered water?

Additional DWQ Regulatory Aspects
• Ensuring credibility of samples analysis results:– Register all Laboratories used by WSIs for sample analysis.– Facilitate the accreditation process between laboratory and
SANAS where required or introduce proficiency testing scheme.
– Ensure the optimisation of analysis methodologies through scientific assessments.
• Usage of safe treatment chemicals:– Ensure that treatment chemicals used comply with the
appropriate SANS standard.– Ensure that all treatment chemicals are registered with
Department of Health.
