Water Act Temporary Diversion Licence


Water Act Temporary Diversion Licence

Water Act temporary diversion licences are issued for diversion of water (surface water and groundwater) for a maximum period of one year. Normally these are issued when there is a need for a short-term diversion and use of water for emergency water supply; for dust control and bridge washing; for drilling oil and gas wells (drilling fluid); and for other short-term uses except those exempted under schedules 3 and 4 of the Water (Ministerial) Regulation and the Water Act.

Application Submission

Proponents/clients use the Water Act temporary diversion licence electronic review system (WATERS) to apply for temporary diversion licences (TDLs). On receipt of an online TDL application, the information is summarized as a document and stored electronically, and a copy is e-mailed back to the client. A public notice of application is then prepared for posting to the AER website at the end of the business day. AER staff and decision-makers use WATERS to review and make decisions on TDL applications. The WATERS system handles the administrative functions of generating the required documents, storing them electronically, and sending results back to the client by e-mail.

Review Process Summary for Water Act Temporary Diversion Licence

  • First Nation consultation adequacy from the Aboriginal Consultation Unit is not needed for TDLs.
  • The system has criteria set that might trigger a technical review by staff. If a technical review is triggered, there might be referrals to specialists or even supplementary information requests (SIRs). Once the technical review is complete, the system generates a template of conditions. Staff can add or change the template conditions based on the technical review. Recommendation for a decision is sent to the delegated decision-maker. Once the decision is made, the system will generate the documents, send an e-mail to the client, and upload onto ERKS.
  • If a technical review is not triggered, the WATERS system automatically issues the licence based on the standard conditions and sends an approval back to the client.
  • The TDL is under an expedited decision-making process.
