NATIONAL WATER RESOURCE STRATEGY 2
• South Africa’s Vision for 2030 demands sufficient water resources
• Water must provide for growth & development
• Our water resource is already stressed
• Water scarcity threatens energy production, food security, economic growth & quality of life
• This strategy addresses current & future water demands for 2030 vision and simultaneously ensure the sustainability of our water resource
Overview of NWRS2
Alignment with NDP
NATIONAL WATER RESOURCE STRATEGY 2
• “Equity, Growth and Development”
• Strategic objectives are aligned to NDP and National Water Act
• Developmental & elimination of poverty and inequality
• Water contributes to economy & job creation
• Water is protected, used, developed, conserved & managed
• Water is controlled sustainably and equitably
Vision of NWRS2
Sustainable, equitable and secure water for a better life and environment for all

Usage of statistics in water business
• Development of water resources• Water resources protection• Water resources allocation• Water use efficiency• Water services delivery improvements
Implication of Census 2011 for Water and Sanitation in Free State
• The Free State has done well in eradicating most of the water supply backlogs.
– Census 2011 indicates that 2% of the 823 316 households still do not have access to water supply services
– A further 5% have supply levels below the basic standard
– And about 6% use communal street taps within 200m
• Sanitation remains a major challenge with 24% of households not having access to basic sanitation facilities
– 5% have no facilities
– 5% still use buckets
– 14% use un-improved / unsafe pit latrines
• In total the Free State requires a further investment of about R9,6 billion to address the remaining water supply and sanitation needs

Key Areas of Data Usage1. Limited water resources (“stretch” existing water sources)
2. Water losses (improve water use efficiency across all sectors)
3. Support economic growth (expanding bulk water infrastructure)
4. Water pollution (manage WWTWs /NPS pollution, protect the
WR)
5. Eradicate the basic services backlogs & manage service levels
6. Infrastructure condition & functionality (refurbish+ improve
IAM)
7. Institutional capacity & service quality
8. Affordable water services & financial viability of WSA / WSP
(future focus)
Status of the above is discussed in the following slides

Limited Water Resources
Free State is surrounded by 2 major rivers the Vaal and Orange river
9
National Surface Water Potential Free State Challenges
Local water resources are inadequate and are starting to fail due to over-commitments
Regional bulk infrastructure is required to bring surplus water from the Orange and Vaal rivers into the interior
Capital and operating costs of RBIG schemes is high and all towns must first introduce strict Water Conservation and Water Demand Management practices
Increased costs, imply higher cost recovery which will affect the affordability of water. Many municipalities are financially constrained and cannot afford the investment required for improved water supply and sanitation services.
However, the interior is experiencing severe water shortages

Industrial water use• water efficient water processes• re-use of water• reduce pollution (treat return
flows)
Mining water use• mining activity & water demand
fluctuates with mineral prices• major risk of heavy metal
pollution and process related chemicals
• promote re-use of water• prevent ground water pollution
Agriculture water use• reduce water losses in canal
systems• promote efficient application
systems• select water efficient crops
Water Use Efficiency

Free State Non-Revenue Water 2012• Water losses = 51% of water supplied• 70% of WSAs need intervention• Loss of revenue = R87m/mth or R1.1b/a • Target 50% reduction in NRW by 2014
