CBH introduced an innovative design for its storage and handling network when it unveiled a raised grid facility at the new Dowerin receival point last week.
The bin's opening was part of more than $30 million worth of upgrades to CBH storage and handling network this month.
CBH Kwinana zone director Mick McGinniss officially opened the Dowerin site last Tuesday.
He was there to cut the ribbon when upgrades at Moora and Brookton were revealed later.
The three upgrades represented an investment of $23m in the CBH storage and handling network.
CBH chairman Neil Wandel said they formed part of a total capital expenditure program of more than $56m to be spent this year on improving the grain network.
He said the spending reflected CBH's commitment to growing value for growers despite the difficult cost environment.
Mr Wandel opened an $8m expansion of the Chadwick receival point near Esperance two weeks ago.
Mr Wandel said CBH was focused on providing the very best storage and handling network for WA growers while keeping charges as low as possible.
Mr Wandel said greater efficiencies have also been created at the Dowerin and Moora receival points with the installation of four new 30,000t open bulkhead storages at each site, with loading capabilities of 500t/hour.
