Strawberry grower Van Aert provides temporary accommodation for his seasonal workers and six mobile homes. The domestic waste water from this is collected and purified by a Phytoair of 8m x 5m for 50IE. The effluent from the aerated helophyte filter is discharged into the stream.
Below you will find 3 samples of the Phytoair confirming the good results: 5, 6 and 18 months after delivery, carried out by a certified laboratory on behalf of the Brabantse Delta Water Board.
