Blue icon with graphic of water glass with arrow to represent UNSDG Goal 6: Clean Water and Sanitation.

In 2022, 2.2 billion people still lacked safely-managed drinking water

The demands that contemporary society places on water resources are immense: water safe to drink; water for agriculture and industrial processes; water for recreation. And when water has been consumed, used or processed, the wastewater must be treated, and runoff must be managed to prevent contaminating the environment and endangering the water supply.

Centre for Water Resource Studies work in the community

  • From Research to Policy: In 2007, Halifax Water entered a research partnership with Graham Gagnon and the Centre for Water Resource Studies (CWRS) at Dalhousie University. The Natural Sciences and Engineering Research Council of Canada/Halifax Water Industrial Research Chair in Water Quality and Treatment is an integral part of conducting the research that informs Halifax Water's internal policies, operational changes, and treatment optimization opportunities.
  • Dr. Gagnon et al. have worked for over a decade to understand and advocate for the role of water safety planning and sanitation safety planning in First Nations water governance and risk mitigation. The team published an article summarizing the role of sanitation safety planning as a guiding framework for First Nations.
  • During 2020/2021 Dr. Gagnon et al. prepared a manuscript (reviewed/revised in 2021, accepted Jan 7 2022) which described a risk-management system created with First Nation water operators to help improve water security and water quality in First Nations in the Atlantic region. The conclusion of this paper highlights the need for data and knowledge management tools for First Nations water operators to ensure safe and clean drinking water. The matrix developed by Dr. Kaycie Lane, a recent PhD graduate of the CWRS is a user-friendly way of conducting multiparameter risk assessments of a water system from source to tap. This work has been extended and applied to the Atlantic First Nations Water Authority (AFNWA).
  • Dr. Gagnon et al. have been instrumental in guiding the formation of the Atlantic First Nation Water Authority, the first Indigenous owned and operated water and wastewater utility in Canada. The 2021 Transitional Implementation plan (page 17) highlights the role of Dalhousie University, through the CWRS, in developing water safety planning for the utility, as well as benchmark standards and interim regulations. This work has national significance, as a new Safe Drinking Water for First Nations Act is currently being drafted.
  • Dr. Gagnon was invited as a key note speaker at the National Environmental Public Health Officer Annual Training for Indigenous Services Canada’s (ISC) First Nation and Inuit Heath Branch (FNIHB) 2022 training conference. The planning and development of the key note address was done in late 2021 and delivered in February 2022.
  • CWRS staff (Dr. Megan Fuller) is a member of the CWWA’s subcommittee on Drinking Water Quality Management and a member of the steering committee that hosted the CWWA’s March 2022 Symposium: Global Lessons for Safe Drinking Water through Quality Management. The activities of the subcommittee bring together water experts across Canada to provide policy and strategy advice for water utilities regarding safe and sustainable drinking water. 

Foundation for inclusion and distinction

Reducing water consumption
Dalhousie measures the total volume of water used in the university against a 2010 baseline with plans to acheive a 70% reduction by 2030. The university has completed many water efficiency projects such as adding sensors to older urinal tanks, installing low flow fixtures and toilets for new and existing buildings, adding rain water cisterns in new buildings, and retrofitting large research water units to recycle water (Aquatron).

Did you know? Using rainwater to flush toilets reduces water use.
The Richard Murray Design Building provides study spaces, design labs,  and an auditorium. 96% of the water used in the building was provided by reusing rain water for toilet flushing at 125 cubic metres in 2022.

Dalhousie is slowing down stormwater using the natural environment and innovative building practices
Developing ways to retain, filter, infiltrate, and re-use stormwater is something Dalhousie University has been implementing as part of new development and renovation projects. Plant material plays a large role in filtering pollutants, slowing the flow of water, and removing water through the process of evaporation.

Sustainable water extraction on campus
Two wells are used at the Agricultural campus to serve aquaculture research. They are managed in accordance to provincial regulations and do not exceed allowances. Water withdrawal is reported annually [PDF-69.9 KB].

Promoting water fountains for drinking water
What began with a taste test in 2008, has resulted in virtually eliminating bottled water on campus in favour of water fountains. The university has well over 100 free to use water fountain/bottle refill stations, many that also keep track of how many plastic bottles have been diverted from entering the landfill.
