Water reuse, sometimes referred to as 'toilet to tap', is gaining ground in thirsty states. There are two methods by which this is done: the first, called direct potable reuse, entails treating wastewater to drinking water quality and redistributing it directly into the drinking water distribution system; the second, called indirect potable reuse, is when wastewater is treated to drinking water standards but returned to some water source, such as groundwater, for eventual reuse.
