2. Contents of a presentation
Overview of water development and planning
Usage of statistics in water business
Implications of census 2011 for water and sanitation in Free State
Areas of water and sanitation coverage for usage of statistics in water sector

3. NATIONAL WATER RESOURCE STRATEGY 2
Overview of NWRS2
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

4. NATIONAL WATER RESOURCE STRATEGY 2
Alignment with NDP
“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

5. Objectives Execution Vision of NWRS2
Sustainable, equitable and secure water for a better life and environment for all
Goal
Water is efficiently and effectively managed for equitable and sustainable growth and development
Objectives
Water supports development and elimination of poverty and inequality
Water contributes to the economy and job creation
Water is protected, used, developed, conserved, managed and controlled sustainably and equitably
Execution
Institutional arrangements
Monitoring & information management
Financing the water sector
Research and innovation
Water sector skills & capacity

6. Usage of statistics in water business
Development of water resources
Water resources protection
Water resources allocation
Water use efficiency
Water services delivery improvements

7. 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 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

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

9. Limited Water Resources
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.
Free State is surrounded by 2 major rivers the Vaal and Orange river
However, the interior is experiencing severe water shortages

10. Water availability
Diagram shows yield available, at 1:50 year assurance of supply, which is only the practically and economically usable portion of the MAR at current development levels and with water infrastructure (dams) as existed in year 2000.
Requirements for the ecological Reserve (which needs to remain in the rivers) already allowed for. Thus "water available" after providing for Reserve.
OBSERVATIONS
Dominance of surface water (± 80 %).
Re-use of return flows greater than groundwater use.
(Return flows to ocean not included).
80 % of water from 20 % of land area in south east of country.
Large transfers into drier areas.
"Transfers" to Lower Vaal, Lower Orange are releases along river from upstream.
NOTE: Yields given at standardised 98% assurance of supply (or 1 in 50 year risk of failure).

11. Water requirements

12. Water reconciliation – Local river catchments
ON NATIONAL SCALE: Still a small surplus for the country. However, national total alone can be misleading because average does not show regional and local surpluses and/or deficits.
Note: Reserve quantity is included in the requirements.
Some WMAs in surplus (e.g. Upper Orange, Mzimvubu to Keiskamma)
Some WMAs in deficits (e.g. Mvoti to Umzimkulu, Berg).
Total RSA in surplus, however:
11 WMAs in deficits in 2000
8 WMAs in surplus in 2000
Important to note that the balances include the Reserve.
Further imbalances within WMAs, also within sub-areas.
BACKGROUND ONLY, SHOULD THE QUESTION BE ASKED:
Upper Vaal shows surplus, based on assuming maximum transfer capacity
In practice, however, only transfer water as needed.
TO PRESENTER: Do not spend too much time on this diagram, rather focus on "The Future“.

Non-Revenue Water
Other Water Use Efficiency Focus Areas
% NRW
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
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
Free State cannot afford this loss !!
