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

National Water Act

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

Elements of Pricing Strategy

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).
