Draft Scope/Description:

1.1 Scope

This standard specifically addresses the planning, design, operation and maintenance of intermittent/seasonal discharge lagoon and wetland systems that are most appropriate for use in Northern regions, where effluent discharge is either difficult, or not possible in colder months.

1.2 Application

In this standard, the North is considered above the 54th parallel. It can also apply in communities where the same challenges appear, such as extreme climatic conditions and remoteness.

This standard applies across Northern Canada to all municipal wastewater lagoons and wetlands used for the treatment of municipal wastewater from:

Cities, towns, villages, hamlets, settlements, community governments and unorganized communities; and

Any site deemed in the public’s interest by a regulatory authority.

Wetland Treatment Areas should only be considered in remote northern environments where costs and feasibility are prohibitive for the use of constructed wetlands.

1.3 Exclusions

This standard does not address mechanical aeration of lagoon systems.
