In November 2017 the City of Manningham in Victoria Australia installed 36 TREENET inlets in a problematic area subject to flooding to improve the recovery time after rain events .
Each inlet was connected to a 300 mm perforated pipe surrounded by aggregate in a 450 diam hole excavatedby hydrovac around existing infrastructure to the maximum depth permitted by bed rock.
The installation of the inlet component by Enviro Eng Civil is the best first effort by any contractor, particularly as no onsite instruction was available . This demonstrates that provided the simple process is followed , particularly the sequence of steps from formwork set up to removal and final finish before fitting the face plate, the result will be to specification.
At the Uni SA City West campus SPACE was installed to protect the root systems of semi mature trees which were previously growing in open ground and were now about to be paved over.Read More
In 2006 this site was allocated for training purposes for the CFS at the rear of Sims Refrigeration Main Rd Blackwood. Originally designed with impermeable paving and extensive stormwater infrastructure to cope with excessive volumes of runoff resulting from fire drill exercises, it did not receive development approval by the City of Mitcham without modification.

In 2006 the City of Adelaide upgraded the footpaths on each side of Pulteney Street in Hindmarsh Square. London Plane trees were planted directly into SPACE filled trenches which were then covered with impermeable paving. All trees are growing well.Read More
In 2007 a new Adelaide Interstate bus depot was built on the site of the old one in Franklin Street in the CBD.
As the site was heavily contaminated with material such as oil, diesel fuel, and heavy metals, a deep excavation was made in the north-west corner of the site and the contaminated soil was buried under a one metre cap of compacted clay.Read More
The Adelaide Entertainment Centre car park is very uneven due to tree roots being unable to penetrate the thick compacted x6 subgrade. Instead they only survive in the thin layer of relatively uncompacted ground immediately beneath the bitumen where condensation provides some moisture.
In 2001 an early SPACE trial was established where several lemon scented gums were removed and Pistachio trees were planted into a 2m square 600 deep hole filled with SPACE which connected the new trees to the natural soil below. Clay pavers were then laid directly over the SPACE and the site was monitored to detect any upheaval caused by the new trees.
After 17 years none has been detected and the trees have developed wellRead More
