Water security for South East Queensland

South East Queensland's (SEQ) long term water security is underpinned by desired level of service (LOS) objectives and a water security program for the region.

On 6 July 2015 Seqwater, the bulk water provider for SEQ, released the Water Security Program for SEQ which outlines the long term planning arrangements and measures in place to facilitate the desired level of service objectives for SEQ over the next 30 years.

The Water Security Program replaces the South East Queensland Water Strategy that was released in 2010 by the former Queensland Water Commission. It includes information about operating the bulk water supply system, future bulk water infrastructure options and drought response. Seqwater will release a second version of the Water Security Program in 2017 following consultation with stakeholders on its content. 

You can participate in Seqwater's community consultation process and have your say on the Water Security Program.

Seqwater also published the Water outlook for South East Queensland which outlines key information on the current water supply security situation in SEQ.

Desired level of service objectives for SEQ

In SEQ the state government has established desired level of service objectives which sets the long- term minimum water security requirements for Seqwater to undertake their water supply planning.

LOS objectives specify the level of performance SEQ residents can expect from their bulk water supply system. The LOS approach aims to ensure:

  • water supplies are adequate in the long term for SEQ
  • customers are aware of what water restrictions may be imposed during droughts
  • the community's basic water needs can be met under foreseeable circumstances, including during drought periods.

A review of the LOS objectives in SEQ was completed in 2014 and the objectives are now outlined in the Water Regulation 2002. Broadly, the desired LOS objectives for SEQ require that the bulk water supply network be able to supply enough water:

  • to meet the projected regional average urban demand
  • so that medium level water restrictions on residential water use will, on average, not occur more than once every ten years, be more severe than 140 litres per person per day or last more than one 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).

The desired level of service objectives also require that the bulk water supply network should be operated such that three key storages (Baroon Pocket, Wivenhoe and Hinze Dams) do not reach their minimum operating level more than 1 every 10,000 years on average.
