Stinky wheelie bins, noisy garbage trucks and scavenging rodents will never plague Maroochydore’s new city centre on the Sunshine Coast.
Rather than employing a fleet of wheelie bins and rubbish trucks, Sunshine Coast Council will suck rubbish from waste inlets in the walls of apartments and commercial buildings at speeds of up to 70kmh through a 6.5 kilometre system of underground vacuum pipes, lurking beneath Australia’s newest, 53-hectare city.
Three colour-coded waste inlets will deal with general waste, recyclables and organics and each will be compartmentalised and sealed underground until the vacuum pump gets switched on to suck it into the central waste facility, probably twice daily. There will also be waste inlets above ground in public areas which will look a bit like daleks.
The waste is then put into sealed compactors and once or twice a week the council receives a message indicating the compactor is full and the waste needs to be collected.
The council’s Director of Infrastructure Services Andrew Ryan said the Swedish system, pioneered in 1965, was already popular in the Northern Hemisphere and would be the first one installed in Australia.
He said the process functioned similarly to sewerage and water systems.
The system will cost $21 million to install but Mr Ryan said costs would be recouped from CBD occupants over the life of the project, around 25 to 30 years.
The council will build the central waste collection centre and charge per property to cover operational and collection costs.
“One of the things we really liked about this system is they work really well in large-scale, medium density masterplan communities [like Maroochydore], particularly where the developer has a long-term interest in the precinct,” Mr Ryan said.
“The most obvious advantages are you have a public realm that doesn’t have garbage trucks trundling up and down the street in the early morning or at night. There’s no noise, no smell and no vermin.
“Buildings can have active frontages because you’re just dealing with a pipe [not bins] and you save on labour costs.”
Mr Ryan said Sydney and Melbourne had a good look at the system but it was difficult for the business case to stack up because of the cost of sinking pipes underground in an already established city centre, although he said Barcelona and Singapore had both done retrofits.
The system was most suited to medium to high density masterplan communities of between 3000 to 5000 people or a resort-style development where five or six buildings were located together.
But it is not just about waste collection. At the same time, the council will install a high-speed fibre optic network as part of its smart cities’ project. This will provide free Wi-Fi hotspots, movement sensors, smart signs and lighting.
The council is not hanging about. The pipes should be in the ground within three months and the central collection centre should be operational by December 2018.
