Applying for Temporary Diversion Licences

(229.05 KB)

Release Date: March 30, 2022


On March 30, 2022, Alberta Environment and Parks (AEP) will stop using the Water Act Temporary Diversion Licence Electronic Review System (WATERS) to receive temporary diversion licence (TDL) applications. Starting April 4, 2022, TDL applications processed by AEP must be submitted to its new Digital Regulatory Assurance System (DRAS). 

This change does not affect TDL applications regulated by the Alberta Energy Regulator (AER). Applications for TDLs related to energy resource activities must continue to be submitted through WATERS. 

A TDL can be issued under the Water Act to allow someone to divert and use surface and groundwater for up to a year. TDLs related to energy resource activities are issued by the AER. All others are issued by AEP.

For further information about AER-regulated applications under the Water Act, see our website, > Regulating Development > Project Application > Application Legislation > Water Act.
