The Watch Tower Society is a religious organisation. One of their site in Indonesia had a septic tank for treating black and greywater from the housing facilities.
The project included the supply of an Aerofloat 13, with process design and installation guidance for a project in Indonesia. The Watch Tower Society needed a greywater treatment system to reduce the load on their septic tank. The Aerofloat 13 treats shower and laundry water before discharging to sewer.
