Best Practice Sewer Charging

Introduction of Best – Practice Sewer Charging

With increasing demands on the limited water resources of NSW, it is vital that these resources are managed in an efficient and sustainable manner.

Best-practice management is essential for efficient and sustainable management of water resources and the environment. It enables a Local Water Utility (LWU) like Wagga Wagga City Council to achieve sustainable water supply and sewerage businesses and comply with the Australian Government's National Competition Policy (NCP) and National Water Initiative (NWI).

LWUs that achieve the outcomes required by these guidelines will have demonstrated best-practice management of these businesses. Best-practice management involves a triple bottom line focus that provides a balanced view of the long-term sustainability of NSW water utilities. Triple bottom line accounting (social, environmental and economic) involves consideration of a LWU's business plan together with its social and environmental management practices.

Best-practice management of water supply and sewerage involves the following 6 criteria:

  • Strategic Business Planning
  • Pricing (including Developer Charges, Liquid Trade Waste Policy and Approvals)
  • Water Conservation
  • Drought Management
  • Performance Reporting
  • Integrated Water Cycle Management

Best-practice sewerage pricing involves a uniform annual sewerage bill for residential customers. For non-residential customers an appropriate sewer usage charge is required for the estimated volume discharged to the sewerage system, together with an access charge/s based on the capacity requirements that their loads place on the system relative to residential customers.

The volume based charge and access charges are detailed below:
