However, the gradual change in standards of life forced them to settle in permanent and isolated places. The need for water also enhanced issues of wastewater disposal. Currently, it is common to discard the raw wastewater to the close surroundings or to septic tanks. The shortage of water forces even the more permanent nomad tribes to have a new look and treatment of the domestic wastewater for possible reuse it for diverse purposes. The separation of the gray wastewater from the rest in the household system is even a better option to use water efficiently and in the future also to have an improved clean environment. The options of reclaiming the gray wastewater in an isolated Bedouin community in the desert area of Israel are presented.
