Dewatering for Deep Excavation – Byron Bay, NSW

Location: Byron Bay

Client: Coastal Works

Duration: 4 weeks

Project Overview: 

The installation of large underground tank required an open excavation approximately 6m deep in an area with shallow water table and sandy soils. Three dewatering pumps were producing a combined flow rate of approximately 30L/sec which required pH correction prior to release into the stormwater system. Two Clearpro DSR In-line dosing systems were used to increase the pH prior to discharge, avoiding any negative environmental and compliance outcomes. The project involved dealing with multiple contractors and a government client.
