Dewatering Highrise Basement

Location – Tweed Heads, New South Wales

Client – Heran Group

Duration – August – December 2017

Project Overview:

Clearpro was engaged as the dewatering contractor on a high-rise building project in Tweed Heads NSW. The basement was dewatered using sumps and surface water pumping when required. Although groundwater inflows into the basement were relatively low, rainfall events resulted in considerable flooding of the excavation. The project was challenging due to indurated sands on the excavation floor resulting in dark brown/black water with extremely high turbidity and suspended solids. A smaller footprint treatment system was able to be utilised on this project due to the low intermittent flows.
