Wastewater treatment plants - Part 1: General design and construction principles

This document specifies the basic design and construction requirements for wastewater treatment plants for over 50 PT. NOTE 1 Requirements for structures which are not specific for wastewater treatment plants are not within the scope of this document. Other ENs can apply. NOTE 2 Equipment which is not solely used in wastewater treatment plants is subject to the applicable product standards. However, specific requirements for such equipment when used in wastewater treatment plants are included in this part. NOTE 3 Although this document specifies the basic design and construction requirements for wastewater treatment plants for over 50 PT, many requirements are only technically and economically feasible at significantly larger sizes.

Frequently Asked Questions about ÖNORM EN 12255-1

When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.

Standardization thrives on expertise and participation. Anyone interested can play an active role in its further development – for example, by joining the relevant committee or a working group. In this way, you can help shape the content and contribute to advancing the state of the art.
