Deloraine WTP automated filter to waste

Deloraine WTP is a Dissolved Air Flotation and Filtration (DAFF) plant and does not have a filter to waste system.

Filter to waste capability allows high turbidity filtrate to be diverted to waste. High turbidity filtrate can lead to reduced drinking water safety outcomes. The lack of an automated filter to waste system contributed to a Deloraine BWA incident in 2018. This project will install an automated filter to waste system.

The Deloraine incident investigation identified this project as high priority for delivery.

The objective of this project is to develop a design for automated filter to waste system, including:

  • Mechanical and piping design
  • Electrical design
  • Civil design to bury existing manual filter to waste piping (or decommission if necessary)
  • Control functional description to allow automation of filter to waste
  • Identify appropriate disposal location for filter to waste to discharge.
