Project Overview

Our project focuses on the reuse of community wastewater recovered from various sources, such as toilets (blackwater) and showers, sinks and washing machines (greywater), as well as the use of harvested stormwater and rainwater.

However, when considering water and resource recovery from an economic perspective, it is important to consider all infrastructure providing water services to a community so as to address human and environmental health, as well as the economy. In particular, wastewater contains embedded energy (heat and organics) that exceeds the total energy used to treat and pump our traditional drinking and wastewaters. Capturing energy (e.g., biogas and thermal heat) that can be used for district heating and nutrients (e.g. nitrogen and phosphorus) for use as fertilizer to sustain our food production are as important to consider as maintaining urban water within the built environment to preserve ecological services in our traditional source water. Most important for a project’s success, however, is acceptance within the community it serves.

Therefore, our project is designed to develop a national road map for water reuse and resource recovery in Canada by utilizing the experiences of various regions, including Australia, Scandinavia and the USA, where our team members have ongoing collaboration in developing guidelines and system analyses for water reuse. Our project also involves engagement with industry, government, academia, and local communities across Canada.

Our research is focused on five areas:

  • Engagement with stakeholders to understand what is socially acceptable for water reuse and resource recovery;
  • Understanding emerging science issues to address what is technically possible for water reuse and resource recovery;
  • Collaborations to improve upon recovering energy, nutrients and other resources from wastewater;
  • Establishing guidelines for safe water reuse through co-development of international best practices; and
  • Developing a framework for implementing water reuse and resource recovery in Canada.
