We have equipped half of the rain water tanks with immerged or on the ground pump, with a 230 µ floating extraction, a 25 µ filter and an active carbon filter for colour and odour treatment. For installations with intensive rain water use, we installed a high capacity active carbon filter with automatic or manual backwash.
