The average American uses 80 -100 gallons of water per day. Less than half is used for cooking or drinking, all of it is most likely treated, potable water from the local municipality. Potable Water: water that is safe to drink or to use for food preparation, without risk of health problems. Alternatively, water can be ‘harvested’ or ‘caught’ from the sky and gathered or stored in cisterns. This ‘catch water’ is then filtered to make ready for human consumption and use through filters.

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.
