Revolutionising Water Storage Construction
A remarkable achievement in engineering and construction efficiency with an unprecedented 75% reduction in construction time for the Port Lincoln 10ML water storage project.
Project Overview
In a remarkable feat of engineering and construction efficiency, together with SA Water, MDJV a joint venture between Diona and McConnell Dowell, achieved an unprecedented 75% reduction in construction time for the Port Lincoln Summit 10ML water storage in 202-2021. This project is part of SA Water’s Water North Framework investment strategy and aimed to improve future water services for the Eyre Peninsula.
Project Need
The need to ensure a continued reliable supply of water to the Eyre Peninsula necessitated the fast-tracked construction of the 10ML water tank. The project aimed to increase the water storage capacity at Port Lincoln Summit from 9ML to 19ML, ensuring adequate water supply to meet the region’s emerging needs.
Project Solution
MDJV innovated the construction process by fabricating 78 pre-cast concrete panels off-site and using a crane for installation, significantly reducing labour intensity and safety risks. This innovative method led to a remarkable construction period of just six months, compared to the traditional two-year timeframe. Additionally, MDJV’s approach included comprehensive earthworks, installation of a dual-layer liner system, leak detection and pipework, further enhancing the tank’s functionality and longevity.
