Treating wastewater to make it available for other uses such as irrigation is a powerful solution to water scarcity, yet it can pose risks to health and the environment if water quality and methods of treatment are not appropriate. Two of ISO’s standards in this area have just been updated to be even more useful in today’s environment.
ISO 16075-1, Guidelines for treated wastewater use for irrigation projects – Part 1: The basis of a reuse project for irrigation, and ISO 16075-2, Guidelines for treated wastewater use for irrigation projects – Part 2: Development of the project, can help maximize the benefits and reduce any related risks incurred in agricultural irrigation systems.
These guidelines outline the factors to be considered in such projects, including how soil and climate can impact water quality. Updates to these standards include additional information related to public and private garden irrigation and further examples of how to improve water quality.
