For the modernization of a wastewater treatment plant near Auckland, innovative Direct Pipe® technology is in use to install a sea outfall pipeline. Over 1,930 meters, the machine is tunnelling its way through the New Zealand subsoil into the sea. That's a world record. The new sea outfall not only increases the plant's capacity, but also sets a new distance world record with Direct Pipe® technology.
Watercare's Army Bay Wastewater Treatment Plant project, on the Hibiscus Coast near Auckland, will create an additional 2.9 kilometre long sea outfall. The pipeline connects the pump station with the discharge point, about one kilometre off the coast. This will increase the capacity of the wastewater treatment plant.
The pipe string is attached to it and simultaneously inserted during the tunnelling process. This is done with the help of the "Pipe Thruster". With pushing power of up to 750 tonnes, it thrusts the pipeline under the ground. Pipeline installation takes place in one step. In this way, the environmental impact is kept low and the landscape remains intact.
The AVN machine was lifted out of the sea at the outfall and towed ashore. The new discharge at Watercare’s Army Bay Wastewater Treatment Plant is scheduled to go into operation early next year and will equip the facility for future population growth.
