The new storm storage includes two large circular tanks, which will each be about 25m in diameter and 18m deep. The tanks are being installed in open ground adjacent to Elmvale Row to provide storage in the combined sewer network to avoid surcharging in storm conditions. The project will also includes the upsizing of 400m of wastewater pipes in the area. A significant amount of rock will have to be extracted during the project.
