Nimbin Water Supply - Pipeline Replacement Project

The water supply to Nimbin town was sourced from Mulgum Creek, where water was drawn from a weir at the top of Gungas Road. This water was chlorinated and delivered by gravity to the DE Williams Dam. The water was stored in the dam, re-chlorinated and pumped to the Nimbin Reservoir to provide water for the residents of Nimbin town as required.

The supply pipeline from the weir had been severely damaged during the 2022 natural disaster. This resulted in approximately 4km of pipeline and road being destroyed, negatively impacting the supply to DE Williams Dam. The damaged pipeline had directly supplied approximately 80 properties in Nimbin town.

The immediate works were put in place as a temporary measure to quicken constructability and secure water supply post-flood event. They have now replaced with a permanent solution, that being a 200mm diameter pipe to ensure hydraulic capacity was maintained.
