Contents of a presentation

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


Overview of nwrs2

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


Use of statistic south africa data in documenting water availability in the free state

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


Use of statistic south africa data in documenting water availability in the free state

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


Usage of statistics in water business

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

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 usage

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


Limited water resources

Limited Water Resources

Free State Challenges

National Surface Water Potential

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

Free State is surrounded by 2 major rivers the Vaal and Orange river

Water use efficiency

Water Use Efficiency

Non-Revenue Water

Other Water Use EfficiencyFocus Areas

  • 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

% NRW

  • 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 !!


Eradicate basic water supply backlog

Eradicate Basic Water Supply Backlog

Free State Total

Free State backlog reduced to 5% of households

  • Remaining challenges:

  • farm workers

  • informal settlements


Water treatment drinking water quality

Water treatment & Drinking water quality


Eradicate basic sanitation backlog

Eradicate Basic Sanitation Backlog

Free State Total

Free State backlog reduced to 24% of households

  • Remaining challenges:

  • informal settlements

  • farm workers


Wastewater management pollution risk

Wastewater management (pollution risk)

  • Map shows the Combined Risk Rating of:

  • capacity exceedance

  • effluent compliance

  • skills deficit

  • delivery & functionality

46% very poor / critical

6% good/excellent

  • Green Drop 2012

  • GD score = 27% avg.

  • CRR risk increased from 81% to 83%

  • non-compliant on >3 effluent const.

  • no WSA got a GD award

  • only 40 of 1384 WWTW got GD awards


Wastewater management green drop

Wastewater management (Green Drop)

No visible improvement in the low risk area

Medium to High Risk WWTW are declining and becoming critical

Critical WWTWare rapidly increasing

= serious problem !

Infrastructure Condition & Functionality

  • Based on Census 2011: water supply interruptions in formal scheme areas:

  • 90% of HH have access to formal schemes

  • 44% of HH experienced water interruptions

  • 75% waited more than 2 days for repairs

Background Legend


Thank you

Census data are critical nerve component for all development yesterday, today and tomorrow in sustaining our limited natural resources such as water in the universe.

THANK YOU
