“Construction of the transfer pipeline will begin in mid-2009, with an aim to ensure the infrastructure is ready, tested and commissioned prior to first water delivery in December 2010,” said Minister for Water Security Karlene Maywald.
Desalinated water will be pumped through the pipeline to Happy Valley, where it will be combined with water from the treatment plant before entering the existing water supply network.
SA Water has identified a preferred corridor for the transfer pipeline between Port Stanvac and the Happy Valley Water Treatment Plant. The 12-15 km corridor has been chosen to minimise environmental and social impacts.
The contractors will tunnel under major road and rail crossings and will also build a pipe-bridge across the Field River to avoid disruption to traffic and environmental impacts. A range of surveys, geotechnical, heritage and flora and fauna studies are underway to determine a more specific pipeline route.
