WestConnex M4 East WTP

Water Treatment

February 2019

About this Project

Gradiant Australia was engaged by CPB Samsung John Holland Joint Venture to design, construct and commission a Ground Water Treatment Plant to provide treatment to the process discharge from the M4 East Motorway Tunnel Project.

The ground water feed delivered to the plant required suspended solid removal, heavy metals removal, and pH correction. The treatment goals were achieved by using a range of treatment processes including basket strainer pre-treatment, chemical dosing, aeration, clarification, media filtration, and sludge dewatering.

The completed WTP is fully automated with control system seamlessly integrated into the client’s existing M4E control scheme.
