Queensland Water Commission Securing our water together

Technical issues paper

Purified recycled water will be added to South East Queensland’s drinking water supplies as part of an emergency drought response when SEQ's combined dam levels reach 40%.  The Western Corridor Recycled Water Project will be one of the largest indirect potable reuse schemes in the world and will have the capacity to deliver up to 232 megalitres a year.

A series of papers have been written by technical experts to provide a detailed technical explanation of the science and engineering underpinning indirect potable reuse schemes. The paper was commissioned by the Department of Natural Resources and Water and the Queensland Water Commission.

Topics covered include:
  • technologies available for water treatment
  • the chemicals and pathogens in wastewater and their removal through the treatment process
  • health risks
  • the risk assessment and monitoring protocols for quality control
  • review of indirect potable reuse schemes worldwide, including their treatment processes, production statistics and motivation for their construction.
