Counting the cost Essential Infrastructure Water Emergency road and water supply restoration works were completed on 30 March 2022, with a damage repair cost estimated to be in the order of $3.5M. Immediately following the February flood event, the Lismore reticulated water network experienced substantial water loss in the High Street Reservoir catchment which serves the Lismore Base Hospital, resulting in significant consumption of our bulk water supply. Council staff worked to isolate sections of the reticulated water supply network to arrest the loss of water within 24 hours, which was largely attributable to damaged hot water systems in flood affected properties. In Nimbin, a 4km length of water main from the chlorination and balance tank was destroyed because of flooding and debris along Mulgum Creek. This section of Gungas Road was effectively destroyed, and the river path was re-directed.
