Project Value
Jaydo was engaged by Greater Western Water (GWW) for the construction of a temporary cross connection pipeline to assist with the storage capacity of the GWW Treatment Plant, Eynesbury Dam & the Bacchus Marsh Recycled Water Plant.
With salvage works delaying completion of the Melton to Bacchus Marsh Interconnector Pipeline project, there was no means to relieve the storage structures at GWW Treatment Plant. Facing an incumbent spill, plans were fast tracked to utilise cross connection that allowed transfer of recycled water from Melton storage, over to Eynesbury storage & then into Jaydo’s recently commissioned 9km GRP pipeline.
key challenges
- Works were accelerated significantly due to inclement weather leading up to the Christmas break. A significant achievement for the Jaydo crew to safely and efficiently deliver the works in the narrow timeframe.
- Works were delivered around culturally sensitive areas with the drill site intersecting between Bunurong, Wurundjeri and Wadawurrung lands, thus requiring 3x separate inductions with different requirements for the 3x separate RAPs which were all audited weekly for compliance, and the inductions requiring detailed planning due to constant changeovers of the crew, subcontractors and staff.
- 5km of temporary fencing and 3km of crushed rock access (10,000 tonnes) was built in unfavourable weather conditions over 2 weeks.
- The accelerated program required multiple work fronts and project coordination from the management team. The collaboration of multiple departments involved in the project showcased the true capability of the Jaydo workforce.
key innovations
The above ground pipeline was an innovative design that reduced the complexity in CHMP approvals and allowed for the fast track build. The pumps were turned on prior to Christmas and avoided the need for any controlled spill.
