CSA S900.2:21

This is the first edition of CSA S900.2, Structural design of wastewater treatment plants.
This Standard was prepared by the Subcommittee on Structural Design of Wastewater Treatment Plants, under the jurisdiction of the Technical Committee on Wastewater Treatment Plants and the Strategic Steering Committee on Construction and Civil Infrastructure, and has been formally approved by the Technical Committee.
This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

There are currently gaps in guidance for structural engineering, construction, commissioning, and maintenance of wastewater treatment facilities. The present structural engineering methodology requires interpretation of non-Canadian standards in a Canadian setting, which might lead to unsafe assumptions in compatibility of design and analysis factors.
The objective of the CSA Wastewater Treatment Plant Program is to develop consistency in engineering and construction methodology. This would achieve benefits enabling more cost-effective design and construction, minimizing jurisdiction-specific regulation development, and reducing overall risk to owners.
