More biosolids from M'boro to be used after $800,000 project

WORK is about to start on an $800,000 project to process more biosolids from the Aubinville plant in Maryborough ready for use as an agricultural soil conditioner.

Wide Bay Water Corporation executive manager operations Denis Heron said there was a lot of work being undertaken around the world to reuse biosolids in agriculture rather than dumping them in landfill.

"For years biosolids from Maryborough and Hervey Bay have been used in agriculture and this work will allow us to use more material from Maryborough which until recently has gone into landfill," he said.

Mr Heron said the biosolids helped improve the condition of the soil by adding organic material and beneficial bacteria.

He said the project involved building a storage facility on land next to the corporation's St Helen's effluent storage facility where the biosolids would be processed.

"The design for the storage area and access roads was prepared by local engineering consultants Engineers Plus," Mr Heron said.

"It will be built by Maryborough company JAC Civil and includes construction of the earth-wall storage area - access roads and rainfall run-off collection systems.

"The works are scheduled to start in May and will be finished in June, weather permitting.

"The stabilised material stored at the site will periodically be applied to nearby sugarcane land."

Treated effluent from the Aubinville Waste Water Treatment Plant is already being used to irrigate crops.
