The Greenbank Sewer Rising Main project was undertaken by Diona in November 2019, for the Logan Water Infrastructure Alliance and involved the installation of 5.6 kilometres of sewer rising main pipeline. They hired a JMS-20-MDT (Diesel, Track) dust collector from Grydale Rental to manage the silica dust created as a result of trenching through sandstone rock. Any excavation works that involves sandstone rock always poses a significant dust and health issue for workers regardless of the excavation method used.
In this project the trencher removed the sandstone rock and the JMS-20-MDT dust collection unit extracted dust and exhausted clean air back into the environment. Diona agreed that conventional methods of dust suppression can be effective but typically involve a lot of water which can cause additional problems and agreed that combining a Grydale dust collector with a trencher provided a much more effective solution and they were able to minimise the risks to workers and also to the greater community.
