CEN/TC 165/WG 50 - Use of treated wastewater
Standardisation of CEN deliverables for on site use of treated wastewater including rainwater and greywater regarding - Principles of design, construction, installation, operation and maintenance (different codes of practice for water reuse from rainwater, greywater and treated wastewater), - Quality (only parameters and test methods how to measure the quality, no threshold values) and quantity in respect of the type of end use, - Product standards (performance, test methods, structural behaviour, guide for installation) for different products, e.g. tanks, filters, controls, treatment units, infiltration units in cases where no specific material related TC or a CEN/TC 165/WG exists. Drinking water purposes are excluded from the scope.

General Information
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.

This document specifies the principles of design, sizing, installation, identification, commissioning and maintenance of greywater systems with the purpose of use of greywater on-site.
It applies preferably for the use of treated greywater for:
- WC flushing;
- garden watering;
- laundry;
- cleaning purposes.
This document also specifies the minimum requirements for greywater systems.
Excluded from the scope of this document are:
- the use as drinking water and for food preparation;
- the use for personal hygiene purposes;
- direct reuse systems without treatment;
- product design for specific system components;
- industrial effluents;
- heat recovery and cooling demands.
