This significant project involved procurement and construction of an 84km x 1930NB water transfer pipeline from the Wonthaggi Desalination Plant to the Cardinia Reservoir. Nacap held the majority share in a joint venture who were contracted to construct the Transfer Pipeline, HV power supply and associated works. Several innovations were developed on the project including the optimisation of the vertical design to minimise the number of air valve installations required, as well as the development of internal and external welding systems to provide a safe access capability for the workforce, whilst maintaining productivity requirements.
This project remains one of the largest water pipelines ever constructed in Australia to date. The transfer pipeline and power supply cable were constructed over a 24 month period, safely and to the highest quality standards during the wettest two years on record.
Self-performed in excess of 90% of the works
Self-performed all land owner and third party negotiations, involving in excess of 100 parties
A large number of pipe and power crossings were constructed through some 85 watercourses including 5 constructed by micro-tunnelling at depths of up to 14m and a large number of road crossings including 6 highway or major arterials. An estimated 18 million vehicle km were travelled by project vehicles during the construction period
Fast tracked project where construction was almost parallel with the design which was on the critical path. The project occurred during two of the three wettest years on record. The project was highly politicised with substantial public antipathy, creating significant liaison activities and community awareness programs.
