Current and Recent Projects
On 6 December 2022, Gladstone Area Water Board appointed the McConnell Dowell / BMD Joint Venture as the preferred proponent for the Fitzroy Gladstone Pipeline with W3Plus Consulting as the Principal Pipeline Designer. The Fitzroy to Gladstone Pipeline Project broadly consists of 116 km of pipeline located in Central Queensland, running through the Gladstone and Rockhampton Regions. The Project connects the Lower Fitzroy River, upstream of the Fitzroy Barrage, to GAWB’s network at Yarwun. It allows the extraction of water from a new intake on the Fitzroy River to a new treatment plant near Rockhampton and then transfer via pipeline to Gladstone and then on to existing and new industrial customers. The Project transfers approximately 30,000 ML of water per annum from the Fitzroy River to GAWB’s existing water infrastructure at Yarwun.
W3Plus was responsible for the hydraulic and tranient analysis, optimisation and design of the Fitzroy to Gladstone Pipeline (FGP), involving the following design scope:
· Approximately 3 km of OD900 HDPE PE112 pipeline and FO cable to connect the FRIPS to the Alton Downs WTP
· Approximately 106 km of OD1067 MSCL pipeline and FO cable to connect the ADPS to Aldoga
· Approximately 8 km of OD1200 HDPE PE112 pipeline and FO cable to connect Aldoga to the MMP
· Mechanical design of the Fitzroy River Intake Pump Station
· Mechanical Design of the Alton Downs Pump Station
· Control methodology for the water transfer system
The facilities required to pump, store, and treat the water are being designed by Stantec, with input from W3Plus.
WNSW proposed replacement of existing dam and pipeline infrastructure to improve the security of water supply to Tamworth due to drought conditions and ageing infrastructure. The project involved design and construction supervision of a new 53 km pipeline from the new Dungowan Dam to Tamworth’s Calala WTP and tying-in to the recently completed Chaffey Pipeline. Hydraulic modelling, optimization and detailed design of the proposed project components were carried out. The project entailed detailed design of approximately 53 km of DN710-DN900 raw water pipeline serving Tamworth together with the detailed civil, mechanical, electrical and telemetry design and documentation of four major pressure control valve installations along the route. Scope also included Safety in Design workshops and the preparation of O&M manuals and as- constructed information.
WaterNSW proposed infrastructure to improve the security of water supply to Tamworth due to the current drought conditions. The project involves installing a temporary structure in the Peel River at Dungowan, together with pumping and pipeline infrastructure at Dungowan (Stage 1). This would be followed by a permanent pipeline and pump station to connect Chaffey Dam to the existing Dungowan Pipeline (DPL) at Dungowan (Stage 2). Hydraulic modelling, optimization and detailed design of the proposed project components was carried out. The project entailed detailed design of approximately 20km of DN750 potable water pipeline serving the Tamworth together with the detailed civil, mechanical, electrical and telemetry design and documentation of the major Chaffey Dam pump station.
