Construction has begun on the Dial Blythe Irrigation Scheme in north-west Tasmania.
Shaw Contracting Australia, was awarded the two construction contracts for the scheme; for the 4000ML South Riana Dam and the distribution network, which consists of two pump stations, 40km of pipeline and over 40 outlets. Local Wynyard manufacturer Zezt Pty Ltd was awarded the pipe supply contract.
The Dial Blythe Irrigation Scheme commenced construction after securing $9.06M in Federal Government funding under the Tasmanian Jobs and Growth Plan and $1.96M in State Government funding from the Water Infrastructure Fund. A further $3.4M in private capital was raised by farmers purchasing water rights.
The project is scheduled to be completed by February 2015 to deliver water in the latter part of the 2014/15 irrigation season.
Water for DBIS will be extracted from the Blythe River above the South Riana Road bridge during winter. It will be stored in a storage dam at South Riana of up to 4,000ML.
Water will be distributed to the scheme over a 120-day summer irrigation period from December through March each year using 42km of pipelines and boost pumps.
Two pump stations will be required, one at the dam site and one at the Blythe River. The pipes will traverse 92 private properties and various crown land holdings.
