The Nicholson Road oxygenation plant is the third of its kind on the Canning River. River water will be pumped to the plant positioned on the bank, where it will be supersaturated with oxygen to very high concentrations under pressure. Water is then pumped both up and downstream along a distribution line, where pressures are maintained in order to keep the dissolved oxygen in solution.

It includes the fabrication of all HDPE pipework and fittings from the plant to the suction well on the intake line and to the discharge nozzles on the distribution line, delivery of all components to site and installation in cooperation with a Commercial Dive company. Works will also be coordinated with the installation of an oxygenation plant, and associated civil works.

Installation of the pipework and weighting system is scheduled for late February and March 2014. Dates are subject to Development Approval (DA) from the Swan River Trust and coordination with other contractors. The successful Tenderer must be able to undertake work within this timeframe.
