In the barren and half-barren regions, the water if became a limitant factor for the urban, industrial development and agricultural, thinking about this some research they are being developed in the direction to reuse the water in less demanding activities in the quality physicist chemistry of this substance. This work had as objective to evaluate residuary the water use treated in the development to aroeira (Myracrodruon urundeuva Allemão), plant found in the Brazilian northeast Caatinga. For this it was measured to each 15 days, after the emergency of 50% plus one plântula, until the 90 days of the dumb a height of the plant (cm) and the diameter of I collect it (mm) of changes irrigated with water of the local supplying, Campina Grande-PB, and residuary water. The results had shown that the residuary water of origin of domestic sanitary exhaustion can be used in fisheries for production of aroeira changes, therefore to all the plants if they had shown vigorous and with good development during the time of it analyzes, ninety days.
