A new standard has been released to help agricultural irrigation projects that use treated wastewater.
The ISO 16075 series contains guidelines for the development and execution of treated wastewater projects, including design, materials, construction and performance.
It covers issues such as water quality, types of crops that can be irrigated, associated risks and main components (e.g. pipeline networks and reservoirs).
ISO, the independent, non-governmental organisation behind the series, said the standards will “reduce any related risks for their agricultural irrigation system”.
The standards include:
ISO 16075-1:2015, Guidelines for treated wastewater use for irrigation projects – Part 1: The basis of a reuse project for irrigation, which contains guidelines for all elements of a project using treated wastewater for irrigation
ISO 16075-2:2015, Guidelines for treated wastewater use for irrigation projects – Part 2: Development of the project, which covers such issues as criteria for the design and specifications for quality
ISO 16075-3: 2015, Guidelines for treated wastewater use for irrigation projects – Part 3: Components of a reuse project for irrigation, which covers the system's components needed for the use of treated wastewater for irrigation.
Dr. Jorge Tarchitzky, Chair of ISO/TC 282/SC 1, the technical committee that developed the standards, said: “Water scarcity already affects every continent. Aquifer water quality is decreasing, and streams, rivers, seas, lands and plants are polluted by wastewater, or affected by lack of its use or improper treatment.
“Properly treated wastewater is an ideal resource to replace freshwater use in agriculture. Treated wastewater can be used for land reclamation, improving agricultural growth and reducing fertilization costs. An environmentally productive use of treated wastewater can also prevent ecological damage to water sources. Other than agriculture, treated wastewater can be used for purposes such urban and industry reuse.”
The new standards are available from national ISO members, a network of national standard bodies.
