Climate Change Impacts on Northern Water and Wastewater

The provision of clean drinking water and the effective management of wastewater (including solid waste leachate) are fundamentally important to maintaining environmental, social, and economic health.

In 2010, Ecology North worked collaboratively with Wekweètì, Déline, and Tsiigehtchic to to assess the vulnerability of their water and wastewater systems to climate change and to create a protocol that may be used by other NWT communities to do the same.

The protocol and individual community assessments can be found below.


Protocol to assess the vulnerability of northern water and wastewater systems to climate change impacts

This protocol is designed to guide communities in an initial assessment of the current and
potential impacts of climate change on their water and wastewater systems. This protocol
presents some background information on the potential impacts of climate change on
water and wastewater systems and guides communities through the process of:

  • Identifying the potential impacts of climate change on their water and wastewater systems;
  • Evaluating the likelihood of an impact occurring (the sensitivity of water and wastewater systems to climate change); and
  • Determining the severity of the impact (the consequences of an impact occurring).

Assessment of the vulnerability of Wekweètì’s water and wastewater systems to climate change impacts 

This report present a general discussion of climate change impacts and then examines the
specific impacts that may affect Wekweètì’s water and wastewater systems.


Assessment of the vulnerability of Deline’s water and wastewater systems to climate change impacts 

This report present a general discussion of climate change impacts and then examines the
specific impacts that may affect Déline’s water and wastewater systems.


Assessment of the vulnerability of Tsiigehtchic’s water and wastewater systems to climate change impacts (NOTE: link to this assessment will be added shortly. June 2020)

Ecology North worked with Tsiigehtchic to create a community climate change adaptation plan. This report is in addition to the community climate change adaptation plan.

Navigating the Waters of Change

The purpose of this paper is to provide a preliminary assessment of the potential impacts of climate change on water and wastewater systems in the NWT and recommend actions to increase the capacity of communities to respond and adapt to changes.

This paper explores the current and predicted climactic changes in the NWT, looking specifically at the impact of increasing precipitation and temperature. The paper considers effects such as permafrost thaw, increased water turbidity, and increase in wastewater levels and the impact they may have on drinking water quality and wastewater treatment in communities across the NWT
