New device taking out the trash on Winding Creek

A pioneering new ‘trash rack’ in Lake Macquarie is trapping plastic bottles and bags, aluminium cans and other waste before it hits our waterways.

Th device – one of the largest in Australian – has been installed on Winding Creek at Glendale, following the discovery of large amounts of waste trapped within mangroves downstream.

Symon Walpole, Lake Macquarie City Council ecosystem enhancement coordinator, said the newly commissioned trash rack was one of a number of Stormwater Quality Improvement Devices (SQIDs) installed throughout the City.

“This updated version employs a new catchment method, where waste and pollutants are diverted and stored in a dry cell onsite. The dry cell makes maintenance and disposal of waste significantly more efficient,” Walpole said.

According to environmental assessment and compliance officer John Parsons, the device used specially designed ‘varies’ to divert debris into a containment cell, while not affecting water flow. In rain events, that cell fills with water, but at other times the water level subsides, allowing for easier rubbish removal.

“The former trash was 25 years old and didn’t effectively capture gross pollutants or sediment,” Parsons said.

The Winding Creek catchment includes the suburbs of Glendale, Macquarie Hills, Cardiff, Cardiff South, Cardiff Heights and Hillsborough, with water draining into Winding Creek and eventually flowing into Lake Macquarie.

“The installation and upgrading of SQIDs across the City are an important component of our water quality improvement program,” Walpole said.

“This program has seen significant improvements in water quality and the health of Lake Macquarie over the past 20 years.”
