Salt HarveSting OperatiOn The salt harvesting operation consists of 240 Ha of ponds located on a 400 Ha site. All ponds are lined with polyethylene to minimise leakage for the ponds back to the groundwater. There is a buffer zone around the perimeter of these ponds that have been revegetated. Pyramid Salt Pty Ltd is expecting to harvest upwards of 36,000 tonnes of salt annually from this site that will be used in the production of a range of salt products that include premium and specialty table salt products, swimming pool salt, and other industrial salt products. pyramid Creek Salt tHe BaSin Salinity ManageMent Strategy 2001–2015 interception Scheme The Basin Salinity Management Strategy 2001–2015 is the Photo of Commercial Salt Harvesting.
