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 reserve
- end long-term drinking water advisories of a year or more on public systems on reserve
- prevent short-term advisories from becoming long-term
Latest news
Recently lifted long-term drinking water advisories

Ensuring essential infrastructure
The Government of Canada works with First Nations to address health and safety needs, ensure proper facility operation and maintenance, 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.
