​​​​​​​​​Water decisions for reference

A list of previously issued decisions narrowed by application category to find out how the AUC considered and addressed certain issues and concerns.

The Alberta Utilities Commission has listed water decisions below to assist anyone who is researching issues that are frequently raised in water proceedings. These water decisions are intended to help you to find information on particular issues and should not be exclusively relied on in the preparation of material to be filed with the AUC​.   

To find additional water decisions and proceedings that involved water issues, please log in to the eFiling System and use the "find" and "search" functions to locate AUC decisions and proceeding material. 

The list below includes decisions issued since 2010 and is not a complete list of water decisions. It will be updated periodically with new decisions. Specific water decision categories can be viewed by clicking the "Water decision categories" drop down arrow on the far right side of the table below. Water decisions are organized into the following categories:

  • investor-owned water utility matters
  • enforcement of safe and adequate water supply
  • franchise agreements - right to provide utility service granted by a municipality
  • long-term water supply agreements
  • appeals by customers of municipal utility charges
  • disputes between municipalities
  • miscellaneous - granting rights to provide utility service 
This list is intended only as a starting point to further aid you in more easily identifying AUC water decisions.
