Reclaimed water working group

A Reclaimed Water Working Group was established to develop a framework to facilitate the safe use of reclaimed water for domestic applications, such as toilet flushing and landscape irrigation, in Alberta. This framework will include new standards and guidelines to mitigate potential health risks associated with using reclaimed water for domestic applications.

Alberta Reclaimed Water Working Group

Four government ministries are participating in the development of the reclaimed water management framework and each is responsible for a particular component of the provincial water system:

  • Alberta Environment – responsible for regulating water treatment and distribution systems, wastewater collection, treatment and disposal systems outside of private properties in Alberta.
  • Alberta Health and Wellness and the Alberta Health Services Board – responsible for monitoring the quality of water and addressing public health issues.
  • Alberta Municipal Affairs – responsible for the building, plumbing and on-site private sewage public safety disciplines in Alberta.
  • Alberta Transportation – responsible for funding municipal water and wastewater treatment infrastructure in Alberta.

The framework being developed by the working group will establish:

  • approved uses for reclaimed water;
  • water quality and technical standards or guidelines; and
  • a management system (e.g. approvals, monitoring and reporting requirements).

Other Initiatives

Work to establish water quality standards, treatment technology standards and best practices is also underway elsewhere in Canada. Nationally, a working group comprised of government officials and invited experts was established by the Federal-Provincial-Territorial Committee on Health and the Environment (CHE) to develop guidelines for using household reclaimed water for toilet and urinal flushing.

Working group members are also participating in development of technical guidelines for reclaimed water systems. The working group is represented on a Canadian Standards Association committee that is developing a testing protocol for the certification of residential non-potable water treatment systems. The working group has also partnered with Canada Mortgage and Housing Corporation, Ontario Municipal Affairs and a number of municipalities to help the University of Guelph develop guidelines for design, construction and maintenance of residential rain water harvesting.
