This document specifies the requirements and gives recommendations for the design, sizing, installation, identification, commissioning and maintenance of rainwater harvesting systems for the use of rainwater on-site as non-potable water. This document also specifies the minimum requirements for these systems. Excluded from the scope of this document are – the use as drinking water and for food preparation, – the use for personal hygiene purposes, – attenuation and – infiltration. NOTE Conformity with the document does not exempt from compliance with the obligations arising from local or national regulations.<\/p>\n
