Clearmake has been contracted by the JV to design, manufacture, install and commission the groundwater treatment plant for the Clem Jones Tunnel (CLEM7).A spokesperson for Clearmake told CIN the value of the contract would not be made public.The system will remove heavy metals and other contaminants from groundwater extracted from the tunnel, so the water is safe to discharge into the local stormwater system.The 6.8-kilometre tunnel, formerly known as the North-South Bypass Tunnel, is being delivered on behalf of Brisbane City Council by Queensland toll road company RiverCity Motorway Group.The tunnel is scheduled to be opened in 2010 and will link five existing major motorways and arterial roads on the north and south sides of the Brisbane River, which combined carry 400,000 vehicles every day.Clearmake said the CLEM7 tunnel was one of the largest infrastructure projects ever to be undertaken in Queensland, and when finished would bypass up to 23 existing sets of traffic lights and provide an additional Brisbane River crossing.It will provide two lanes of traffic in each direction and when completed, will be the longest road tunnel in Australia.
