Wastewater in First Nations communities

Learn about wastewater in First Nations communities.

Disposing of wastewater and sewage

Wastewater is also known as sewage. It can harm humans, as it can:

  • spread diseases
  • pollute surface and groundwater sources

Indigenous Services Environmental Public Health (EPHP) program's focus is on:

  • on-site sewage disposal systems
  • community sewage treatment systems

To reduce and prevent public health risks, we:

  • detect current and potential hazards related to sewage disposal
  • help First Nations plan and site their single sewage septic systems
  • review plans and provide advice for new and upgraded wastewater treatment systems

For sewage systems on federal and Aboriginal lands as defined under the Canadian Environmental Protection Act, 1999, Environment Canada:

  • develops standards, guidelines and/or protocols
  • provides advice and technical expertise on federal legislation requirements
