What We Do

The OWWA Treatment Committee is a volunteer group consisting of representatives from Ontario utilities, consultants, academia and our regulatory authority MECP with a technical focus on drinking water treatment. The Treatment Committee meet virtually once per month to discuss and further our two main objectives in support of our OWWA membership and the general public which are: the support of knowledge transfer between industry partners; and the provision of technical feedback in treatment-related regulatory and guidance documents. 

The committee supports knowledge transfer through several activities including: organizing an annual Treatment Spring Seminar; supporting abstract review and session organziation for treatment sessions at the OWWA Annual Conference; organizing plant tours, often in collaboration with our Young Professional liaison; and through authoring and submitting articles to industry journals. Technical feedback consists of participating in public review of draft documents for Ontario regulatory updates and Health Canada guidance documents, in which committee members provide both direct technical feedback and encourage and collate feedback from within our broader technical networks.

Our Activities

The Treatment Committee achieves these goals through four main annual activities: Seminars, Tours, Technical Reviews, and Publication of Articles.

Annual Seminars

Every year the Treatment Committee organizes a Spring Seminar, normally in late March, on subjects relating to drinking water treatment.

Technical Reviews

The Treatment Committee routinely reviews:

  • Provincial and federal proposed drinking water regulations and guidelines
  • Abstracts for the treatment sessions at the annual conference
  • Abstracts for the Treatment Spring Seminar

The Treatment Committee also offers comments through the Environmental Bill of Rights public consultation process.


The Treatment Committee typically co-hosts a WTP plant tour each year with the Young Professionals Committee. 

Publication of Articles

The Treatment Committee prepares articles on treatment-related issues for publication in the OWWA Pipeline. Click on the recent articles below.
