Résumé:
The availability of water does not occur uniformly in the state of Paraíba, has annual water availability below 1,500 m3 / inhabitant decreasing even more. With the current water shortage, drip irrigation systems allow the minimization of water consumption. The use of wastewater from urban activities has potential for use in irrigated of agriculture, provided that the water quality and its potential damages to the system are observed. This work aimed to make possible the reuse of water in the irrigation located by drip system, using the quality control tool. The experiment was carried out in a controlled environment (greenhouse) belonging to the Irrigation and Drainage Laboratory of the Academic Unit of Agricultural Engineering, Federal University of Campina Grande. Two types of lateral lines consisting of two specific dripper models, submitted to two different water sources, were evaluated. Performance indices obtained non-random behavior, with values that exceeded control limits, especially in the final study trials. The cistern-fueled system achieved considerable performance until approximately 648 hours of operation, while for systems supplied with wastewater, The performance was around 576 hours.
