Successes & Challenges

3. RANDWATER Footprint
Rand Water is a public utility wholly owned by government (DWS)
Abiding by the Water Services Act (Act 108 of 1997)
KEY Figures
Bulk Water supplier Mℓ/d Consumers - Over 11 million Total Pipeline Length km Total Number of Reservoirs - 58
Supply Area km2
Additional km2 area of service
Equals significant reach
RW vision: To be a provider of sustainable, universally competitive water and sanitation solutions for Africa

4. BULK SANITATION department
Bulk Sanitation dept. formed to address:
impact pollution will have on the quality and treatment cost of potable water – as main polluters in RW catchment identified as waste water treatment works (WwTW’s) discharge (as per RW Catchment Management Programme - CMP)
The primary focus of Bulk Sanitation therefore is to:
Extend Rand Water’s CMP;
Conduct assessments of the WwTW’s  in the catchment,
Report on these findings &
Provide site-specific recommendations to the respective municipalities to guarantee effluent compliance – as well as provide technical support

5. BULK SANITATION value chain
Management, Operation &
Maintenance of Wastewater Treatment Plants
Industrial Effluent Monitoring Programme
Refurbishment of Wastewater Treatment Plants
Effluent
Re-use
Capacity building through on-job training
BULK SANITATION VALUE CHAIN

7. Bulk Sanitation - BEST practice
Often adopted as a standard way of conducting certain activities
“…method/technique which is viewed as the most efficient means of undertaking an activity…”
Can evolve & improve in similar future activities
Best Practice

8. Bulk Sanitation - BEST practice
Improving the life & health of the people by ensuring that the final effluent is of good quality and is free of micro-organisms posing threat to human health
Preserving water resources and protecting the environment by ensuring compliance of effluent with legislation (WUL)
Monitoring and reporting the WwTW’s performance to the owner & the DWS
To provide specific recommendations to the respective municipalities that guarantees system improvement
Continuous improvement and refinement
GUIDING PRINCIPLES
