Heathcote WTP has a nominal inflow capacity of 5.5 ML/d and treats water from the Lake Eppalock or Caledonia Reservoir for the supply of drinking water to the towns of Heathcote and Tooboorac.

- Disinfection upgrades to meet the new proposed Health-Based Targets to be incorporated in the Australian Drinking Water Guidelines including:
- Power Supply and Main Switchboard Upgrade
- Ultraviolet (UV) disinfection.
- Modifications to the existing plant to achieve free chlorine contact time.
- New powdered activated carbon (PAC) system to remove taste and odour compounds from the water
- New wash water handling system to treat wash water and recover supernatant onsite, requiring geobags and laydown areas, thickeners, supernatant handling, and polymer dosing equipment.
- All testing and commissioning, O&M Manuals, WAE Drawings and Operator Training
