Important notice

Effective April 4, 2022, Water Act applications for temporary diversion licences (TDL) and amendments must be submitted through the Digital Regulatory Assurance System (DRAS).

The Water Act Temporary Diversion Licence Electronic Review System (WATERS) will no longer accept new TDL applications from Alberta Environment and Parks (AEP) applicants.

Active TDL holders will continue to review and manage their previously issued authorizations in WATERS. This also applies to any pending TDL applications submitted on or before March 30, 2022, in WATERS.

Any TDLs that were issued via WATERS will continue to require reporting in the Water User Reporting System (WURS). Any TDLs that are issued via DRAS will report directly in DRAS.

WATERS will still be active for Alberta Energy Regulator applicants.


On June 21, 2021, Alberta Environment and Parks took a significant step towards streamlining its regulatory system with the new Digital Regulatory Assurance System (DRAS).

For more information on DRAS see: Digital Regulatory Assurance System.
