The Water Corporation will start work next week on a $20.6 million project to construct two 37.5 million litre water tanks west of Cunderdin.
Water Minister Mia Davies said the new tanks would improve water quality and provide increased storage for the Water Corporation's Goldfields and Agricultural Region Water Supply Scheme.
"The two new tanks will be about 64 metres in diameter and 13 metres high, and will store enough water to fill more than 33 Olympic swimming pools of water," Ms Davies said.
"People driving along Great Eastern Highway will spot the new tanks about five kilometres west of Cunderdin, near Mussared Road.
"The Water Corporation will also install about two kilometres of pipe to connect the tanks to the Goldfields and Agricultural Region Water Supply Scheme. Trenchless technology will be used to tunnel under the Great Eastern Highway to minimise impacts on road users."
The Minister said the Water Corporation had worked with the Cunderdin community to determine the location of the new tanks.
"Thank you to the community members who provided input into the location of these tanks to ensure impacts are minimised," she said.
Work on the project is expected to be complete by September 2017.
Ms Davies said the new tanks were in addition to the three-year $32 million farmlands water supply improvement program that began in December 2015.
"The farmlands program will improve the performance of the water supply network across the Wheatbelt," she said.
"More than 64 kilometres of pipeline will be replaced, 7,500 pipeline joints will be repaired and smart water meters will be installed across the farmlands scheme to help save water."
The new tanks will form part of the Goldfields and Agricultural Region Water Supply Scheme, which provides water to Water Corporation customers through more than 9,600 kilometres of mains
The scheme forms part of the Integrated Water Supply Scheme, which sources water from desalination, groundwater and surface water
