Liquid Waste Water Treatment

The liquid waste water treatment system is a containment, treatment and distribution system for liquid waste water. This system is similar to the wetlands concept which has long been used in exterior applications for thousands of years by humans and nature. This system differs from the wetlands approach in that it treats and processes the ‘untreated greywater’ inside the building.

Catching Water from the Sky

Water is caught from a roof with a potable surface. From the roof, the water is channeled through silt catches into cisterns. Cisterns are sized to the local climate and are best buried and completely protected from the sun. The water from the cistern is gravity-fed into a Water Organizing Module with a pump and filter. The pump pushes the water into a pressure tank to supply code required water pressure. The filters clean the water for consumption and cleaning.
