Billion dollar stormwater control

Walking back down Broadway today I checked the stormwater pond on the north western corner of the billion dollar Frasers’ Broadway project.  The photo shows world best practice stormwater control which is directing muddy water off site to Blackwattle Bay.  A pit in the centre of the muddy pond has some fabric pinned into the mud by four star pickets and the water in the pond fills and enters through the fabric to the stormwater pipes and thence to the harbour.   Last night’s rain and mud is visible in the stormwater pits today as the billion dollar project continues to allow excavation mud to wash off.  It appears as tho’ the shopping trolley won’t fit into the pit’s drain.
