South East Queensland water security

The Department of Natural Resources, Mines and Energy provides a framework to provide long-term water security for South East Queensland (SEQ), as prescribed in the Water Act 2000. The aim is to ensure the delivery of a sustainable and secure water supply.

The framework:

  • provides for the desired level of service (LOS) objectives for water security in the SEQ region
  • requires the bulk water supply authority to have a water security program to facilitate the achievement of the desired LOS objectives.

Water security program

The department's Water security program for South East Queensland: Guidelines for development (PDF, 355KB) provides Seqwater with information and guidance on the content of the program.

This program outlines the long-term planning arrangements for the desired LOS objectives for SEQ over the next 30 years. It includes information about operating the bulk water supply system, future bulk water infrastructure options and drought response.

Desired level of service objectives for SEQ

The desired LOS objectives are set in the Water Regulation 2016.

These objectives for SEQ require that the bulk water supply network be able to supply enough water:

  • to meet the projected regional average urban demand estimated by Seqwater, so that medium level water restrictions on residential water use will (on average) not occur more than once every 10 years, be more severe than 140 litres per person per day, or last more than 1 year
  • to provide an essential minimum supply volume of 100 litres per person per day in an extreme drought event (i.e. a 1 in a 10,000 year event), so that key storages (i.e. Baroon Pocket, Wivenhoe and Hinze dams) will not reach their minimum operating level more than once in every 10,000 years on average.

Review of desired LOS objectives

We are currently working with Seqwater on a review of the LOS objectives. This review should be completed in 2019.
