Construction on the new Kwinana depot UAN liquid fertilizer storage facility reached another key milestone in late winter.
Summit Fertilizers Executive Manager Engineering and Mainten-ance, Phil Hargreaves, advised staff on August 31 that pumping of UAN across to the new storage facility had commenced.
“Hydrostatic testing and a range of other system checks meant we were able to start transferring liquid UAN over from our existing tank facility. This is another key milestone for us.
Completion of pipe work to connect the two facilities to full capacity, which allows UAN stored in the ponds to be used for dispatching, is next,” he said.
“The facility has heavy duty primary and secondary HDPE linings, UV stable top covers and a state-of-the-art leak detection system to safeguard UAN management.
Pipe work is progressing to fully interconnect the new storage facility with existing depot tanks and truck despatch. Milestone Services Managing Director/Project Manager Lee Benger (right) and Summit Fertilizers Executive Manager of Engineering, Phil Hargreaves, inspect the progress.
“Electrical work, pumps and instrumentations are now all in place which means we are well positioned for this UAN storage to be fully operational for next season” Phil said.
The Kwinana depot upgrade will expand Summit’s ability to store and supply liquid UAN (urea ammonium nitrate) by adding a further 50,000 tonnes of storage capacity.
