Adverse effects to human health and environment safety are the most significant concerns that have to be considered in the re-use of treated wastewater and thermal treated sludge in agriculture and irrigation purposes. These concerns are attributed to the presence of pollutants, such as organic matter, toxic chemicals impact once the wastewater and sludge are released to the environment. This guideline is prepared consistent with the provisions of local ordee no. 61 of 1991(Protection of the Environment in the Emirate of Dubai), which lay down the foundation of regulating the reuse and land disposal of treated wastewater and sludge within the Emirate of Dubai. Also, this guideline provides minimum standards and common approach for the reuse of treated wastewater and sludge as well as minimum requirements for the design of distribution systems of treated wastewater to ensure reuse and eventual release to the environment will not in any way compromise public health.

- Restricted Irrigation - The use of treated wastewater to grow crops that are not eaten raw by humans
