  1. Towards a WDCS 1 TOWARDS A WASTE DISCHARGE CHARGE SYSTEM forSOUTH AFRICA PRESENTERS: Pieter Viljoen (DWAF) Dr. Judex Oberholzer (Urban-Econ) Assisted by: Robyn Arnold (Communication) Martin Grosskopf (Modeling)

  2. Organisation 2 ORGANISATION OF THE WORKSHOP Programme Handout & supporting document Questions on cards Information posters

  3. Aims of the workshop 3 AIMS OF THE WORKSHOP Present proposed Waste Discharge Charge System Obtain feedback from stakeholders: possible adjustments Identify limitations

  4. CONTENTS 4 CONTENTS OF PRESENTATION

  5. Why address water quality? Introduce system (1964): 30 fish species Some rivers in RSA same condition 5 WHY ADDRESS WATER QUALITY ? Seine river in Paris: one fish species (1961)

  6. What is the WDCS Note: Not a pollution charge 6 WHAT IS THE WDCS ? The WDCS is a framework for charging for the discharge of waste into water resources. It aims to use economic instruments to encourage impactors to: Internalise the social, economic and ecological costs of discharges Reduce the amount of waste discharged into water resources

  7. Water problems in RSA • Country is semi-arid • Rainfall patterns erratic • Regions of high runoff away from areas of maximum demand • Groundwater limited and poor quality • Catchments infested by invader vegetation (Working for Water) • Water quality deterioration impact on availability 7 WATER PROBLEMS IN RSA Factors that influence the supply of water in South Africa • Assimilative capacity of the water resource is reduced • Opportunity to use resource diminished

  8. Demand on water resources 1. The high population growth rate 2. Rapid urbanisation 3. Economic development 4. Demands for higher levels of service 5. Aquatic eco-system is negatively impacted and requires rehabilitation 8 DEMAND ON WATER RESOURCES IS GROWING

  9. Extent of water resource pollution Main pollutants (national approximation) tons per year TDS 650 000 TP 19 000 NH3/NH4 3 400 NO2/NO3 9 700 Suspended solids 26 000 9 EXTENT OF WASTE CONSTITUENTS IN WATER RESOURCES

  10. Catchment System CATCHMENT SYSTEM: CORE MESSAGE “EVERYBODY LIVES DOWNSTREAM” • 11 Water uses • 5 Water users 13

  11. 14 USERS Dictating the water quality requirements Users & Uses S21(a) Taking water from a resource S21(b) Storing water S21(c) Impending or diverting the flow of water in a watercourse S21(d) Engaging in a streamflow reduction activity S21(e) Engaging in a controlled activity S21(f) Discharging waste or water containing waste into a water resource S21(g) Disposing of waste in a manner which may detrimentally impact on a water resource S21(h) Disposing in any manner of water which contains waste from, or heated in, any power generation process S21(i) Altering the bed, banks course or characteristics of a watercourse S21(j) Removing, discharging or disposing of water found underground S21(k) Using water for recreational purposes Agriculture USES Potentially impacting on water resource Industry Recreation Domestic Aquatic ecosystem Refer to Poster on DWAF website

  12. 21(e) 15 • 21 (e) / S37(1a) Engaging in a controlled activity • Irrigation industrial/ mining • Oxidation pond overflow • Sewerage sludge

  13. 21 (f) 16 • S 21 (f) Discharging waste or water containing waste into a water resource • Domestic waste • Industrial waste • Mining waste • Stormwater • Irrigation return-flow channels

  14. 21 (g) 17 • 21 (g) Disposing of waste in a manner which may detrimentally impact on a water source. • Oxidation ponds • Slimes dams (industrial/ mining) • Evaporation dams (industrial/ mining) • Stormwater

  15. National Water Act 18 NATIONAL WATER ACT (NWA) The Minister may, with the concurrence of the Ministry of Finance, from time to time by notice in the Gazette, establish a pricing strategy for charges for any water use within the framework of existing relevant government policy. Section 56 of the NWA instructs the Minister to establish a Pricing Strategy: • For funding water resource management • For funding water resource development and use of waterworks • For achieving the equitable and efficient allocation of water

  16. Elements of Pricing Strategy 19 ELEMENTS OF PRICING STRATEGY • Only applied to water management areas or schemes where annual water use has been registered or licensed. • End user for which unit sectoral charges will be calculated are: • water services authorities • industrial, mining and energy • irrigation • stream-flow reduction activities • Funding Water Resource Management: regulate, manage and maintain the water resource / catchment. • The budget allocated to the following: • Functional support (from regional offices) • Planning and implementation of catchment management strategies • Dam safety control • Water quality management • Water utilisation • Water conservation (including the Working for Water programme).

  17. Point source discharges 20 POINT SOURCE DISCHARGES S 21(f) Groundwater S21(e) Water use sectors Controlled activity (Irrigation) Section 21(e) Evaporation Pond Section 21(g) River • Notes • Point sources • Diffuse sources

  18. Overview of charges OVERVIEW OF CHARGES (NWA) AND WATER SERVICES ACT TARIFFS Recreation charge (NWA) Abstraction charge (NWA) Water supply tariff (WSA) Trade effluent tariff (WSA) Sewerage tariff (WSA) Waste discharge charge (NWA) 1 2 3 4 5 6 21 Resource: Dam 1 Mining 2 Treatment Plant 2 2 6 6 3 3 Industry Domestic users 5 6 4 Resource: River Waste Water Treatment

  19. Marine outfall 22 MARINE OUTFALL: DWAF RESPONSIBILITY Fresh water resource Domestic Water use sectors River Pump station Section 21(h) Section 21(f) • Note: • Legal mandate • Resource definition (exclude marine environment) • Water containing waste • Water is used to transport waste Estuary Ocean

  20. WDCS and the Policy Environment Important conclusion…. The WDCS will become a subcomponent of the Pricing Strategy. This research process is to determine how to incorporate a Waste Discharge Charge System into the Pricing Strategy 23 WDCS and the Policy Environment
