Over deze norm
NEN-ISO 16075-1 contains guidelines for the development and the execution of projects intending to use treated wastewater (TWW) for irrigation and considers the parameters of climate and soil. The purpose of these guidelines is to provide specifications for all elements of a project using TWW for irrigation, including design, materials, construction, and performance, when used for the following: - unrestricted irrigation of agricultural crops; - restricted irrigation of agricultural crops; - irrigation of public and private gardens and landscape areas, including parks, sport fields, golf courses, cemeteries, etc; - irrigation of private individual gardens. These guidelines are intended to provide assistance for the benefit of users of TWW for irrigation. The guidelines relate to the widespread and common ranges of water quality rather than exceptional or unique ones and are intended for the use by professionals, such as irrigation companies (designers and operators), agricultural extension officers or advisors, water companies (designers and operators), and local authorities. The use of these guidelines by farmers might require additional specifications. None of the parts of this International Standard are intended to be used for certification purposes. These guidelines suggest the parameters of TWW quality. These parameters include the following: - agronomic parameters: nutrients (nitrogen, phosphorus and potassium) and salinity factors (total salt content, chloride, boron, and sodium concentration); - other chemical element parameters (heavy metals); - microbial parameters. Each of these parameters can have possible impacts on the crops, soil, and public health. The guidelines discuss the possibility of preventing the contaminants’ presence during wastewater production and the ability to remove them during the course of treatment. Emerging pollutants (pharmaceuticals and personal care product residuals) are outside the scope of this part of ISO 16075 since at this time, they are not included in any national standard. The project should be designed in accordance with the sanitary quality of the TWW in order to avoid disease transmission by the pathogens in the water. The use of these guidelines is encouraged to ensure consistency within any organization engaged in the use of treated wastewater.
