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

15National 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
16Elements 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).
