Ending long-term drinking water advisories

Everyone in Canada should have access to safe, clean drinking water. The Government of Canada is working with First Nations communities to:
- improve water infrastructure on reserves
- end long-term drinking water advisories on public systems on reserves
- prevent short-term advisories from becoming long-term

Recently added long-term drinking water advisories
Ministikwan Lake Cree Nation (SK) as of March 9, 2021
A drinking water advisory in Ministikwan Lake Cree Nation (Sasktachewan) on the Ministikwan Lake Cree Nation Public Water System became long-term on March 9, 2021, after being in place for more than 12 months. The advisory was initially recommended due to a water line break and loss of pressure to the distribution system. The First Nation has maintained the advisory due to occasional disruptions caused by construction shutdowns, power outages, and seasonal high chlorine demand, and has indicated the advisory will remain in place until the new water treatment system has been completed. ISC is currently working with the First Nation to construct a new water treatment plant. The project is nearing substantial completion, but it has been delayed as a result of COVID-19-related issues.

Ensuring essential infrastructure
The Government of Canada works with First Nations to address health and safety needs, ensure proper facility operation and maintenance, and to prevent short-term advisories from becoming long-term.
Ending a drinking water advisory is often complex, spanning multiple phases. Actions to resolve a water or wastewater issue can include:
- feasibility studies
- new system design work
- interim repairs on existing systems
- permanent repairs to existing infrastructure
- construction of new infrastructure
- improved training and monitoring
Completion of a new water treatment system can take 3 to 4 years on average to complete. See the Life-cycle of a First Nations community infrastructure project.

The Government of Canada is working with First Nations to end long-term drinking water advisories (LT-DWAs). In the table below, "LT-DWA" refers to long-term drinking water advisories which have been in effect for more than 12 months. ISC provides funding for public water systems that serve five or more household service connections for residences that are occupied year round. ISC also provides funding for public water systems serving public facilities funded through ISC. These water systems are managed and operated by the band, a band-owned utility or qualified third party under contract.
