Water re-use system for Milligan Street

A new stormwater drainage storage basin installed as part of the MRA’s Milligan Street precinct works, will play a key role in enhancing the sustainability of the precinct.

Being built below the public landscaped area along Wellington Street, the underground basin (or detention tank) is designed to receive and store stormwater run-off from the public landscape and new roads.

Not only will the basin provide storage capacity for run-off during severe rainfall events, it also has additional storage capacity (approximately 100,000 litres) for recycling stormwater that will be used for landscape irrigation and to feed the water feature that will form part of the future Bridge Plaza pedestrian link over the rail line.

The basin includes a pollutant trap that filters incoming stormwater to ensure it is suitable for use in the public realm.

“This is a great sustainability initiative which will help manage water demand for public spaces within the precinct,” MRA Acting CEO Veronica Jeffery said.

The concrete basin has an overall storage capacity of 348,400 litres, is approximately 1.5m deep and at its widest point measures 24m x 12m.
