The course is in the shape of a massive 'U', 320 metres in length, between 0.8 and 1.2 metres deep and between eight and 12 metres wide. The overall drop from top to bottom is 5.5 metres. During events a conveyor belt is used to take boats, and their occupants, from the finishing pool back to the start. As the course has been built in a relatively flat area (flood plain), it has been built up and landscaped to create the sloping course necessary for the required rapids. By design only five of the six available 300-kilowatt pumps are needed to lift the water from the bottom to the start of the course, at the rate of 14 m³/s. This leaves one pump spare for maintenance. The channel is constructed from concrete with sloping sides. A special blend of concrete was developed to demonstrate sustainability of construction. Very high rates of replacement of cement by power station fly ash were used for the first time in Australia. Large granite boulders are used to shape the water course, as well as a system of movable obstacles which may be used for varying the difficulty of the course and for fine-tuning of the rapids. The total cost of construction was $AU6 million, of which $1.5 million was paid by
Penrith City Council, $1.5 million by the
International Canoe Federation (including $300,000 by
Australian Canoeing) and $3 million by the
Government of New South Wales. ==Facilities and uses==
