CSA - Exploring Potential for Construction of Water and Wastewater Treatment Structure

Print Print this Article | Send to Colleague

CSA Group is determining the feasibility of developing a suite of standards dealing with the design and construction of water and wastewater treatment structures.

We are seeking your feedback on the following assumptions:
  1. Standardization is necessary to develop consistency in design and construction due to the number of gaps and that require adaptation of National Building Code of Canada and US documents;
  2. Not having clear standards leads to higher costs of repairing and retrofitting problematic facilities;
  3. The intended audience for these standards should be engineers who are responsible for designing the infrastructure, material producers, contractors, provincial and municipal engineers responsible for reviewing and approving designs, regulatory inspectors, and the municipalities/owners of the infrastructure

The design and construction of water and wastewater treatment systems within the structure (facilities) would be outside of the intended scope.

Much appreciated if you could forward this communiqué to others so that we can get a broad range of opinions.

Based upon your feedback and that of other stakeholders, CSA may organize a workshop in the Fall with the purpose of obtaining initial buy-in to develop CSA standards on water and wastewater treatment structures. Workshop would set out to accomplish the following:
  • Highlight issues in design and construction using presentations that include case studies
  • Confirm need for standards (including possible reduction in design and repair costs if standards are developed)
  • Discuss program duration and funding models
  • Rough in scope of committee
  • Rank the possible standards, in order of importance
Stakeholders could include:
  • Construction firms
  • Department of Fisheries and Oceans (Federal)
  • Design consultants (including earthquake experts)
  • Local conservation authorities
  • Ministry of the Environment (Provincial)
  • Ontario Clean Water Agency
  • Regulators from municipalities, regions, and provinces
