TRT worked closely with Watercare to provide a transport solution to haul treated biosolids from the adjacent Mangere Wastewater Treatment Plant backfilling an old quarry to create a new regional park. The ultimate solution was two trains of 3 sidetipping wagons pulled by Fendt tractors. The drivers are able to operate all 3 trailers from their tractor cabs, including tarpaulin covers and tipping, which can be individual or multiple. Each wagon is able to be hitched up in any formation simplifying maintenance and reducing down time.
