SLOW IT DOWN, CLEAN IT UP | A NEW BIO-RETENTION INSTALLATION
27 Jun 2019
The installation of two bio-retention basins in Bardon Ridge required a powerful machine to complete the job quickly and efficiently. Find out why the Scapeworks Australia's Rockslinger was the ideal solution.
Scapeworks Australia installed two bio-retention basins for Western Earth Moving in Bardon Ridge, a suburb in the Sutherland Shire NSW. The material installed included blue metal and other filtration media at specified amounts.
The work was completed in one and a half days with a total of 900 cubic metres of material placed through the powerful machine. A 15T excavator loaded the Rockslinger onsite to create an efficient and exact system, enabling the job to be done quickly without compromising the basin’s structural integrity.
ONE TONNE A MINUTE
The Rockslinger can install material one tonne per minute directly into place via a line of site slinger system. It has been used for filling trenches, planter boxes, drainage systems and even pool refits. The speed and accuracy of the truck is useful where time and money is tight or where machinery can’t travel.
The technology was recognised as a cost-effective and quick labour-saving device. The Rockslinger trucks complement Scapeworks' blower system where logistics are challenging or where time is important. 
WHAT IS A BIO RETENTION BASIN?
Bio-retention basins slow the flow of stormwater and facilitate filtration for eventual flow into the broader stormwater system. These basins are often installed around new development and other manmade hard surfaces that may result in increased volumes of water runoff.
A well-designed bio-retention basin can enhance the natural and visual amenity of an area, where water, plants and wildlife gather to enjoy an ecosystem carrying out a functional stormwater job.
These installations are made up of layers of material with different permeability characteristics. The water flows into and through the profile of the basin in a controlled manner, filtering and directing both the liquid and debris. In a good design, the FAWB (Facility for Advancing Biofiltration) guidelines are referred to for best results.
