Treated wastewater reuse for irrigation -- Guidelines for the adaptation of irrigation systems and practices to treated wastewater

This document provides guidelines to planners and practitioners on how to adjust irrigation equipment so as to allow direct utilization of treated wastewater (TWW) for irrigation. It deals with the adjustment of all components of irrigation systems to TWW quality in respect to physical, chemical and biological parameters.

This document provides guidelines on how to protect irrigation equipment so as to guarantee water systems functionality at high levels of efficiency.

This document includes recommendations for

a) pumping stations,

b) filtration,

c) water network systems,

d) irrigation equipment: emitters (drippers, sprinklers, mini sprinklers, micro sprinklers, sprayers and irrigation machine (sprinklers and sprayers),

e) physical treatment of irrigation equipment, and

f) chemical treatment of irrigation equipment.

This document defines TWW parameters at the irrigation system inlet after a wastewater treatment plant, in order to allow optimal and continual functioning of the irrigation systems and to allow uniformity of emitters' discharge.
