Integrated Sorption Technologies for Recovery of Nitrogen and Phosphorous from Anaerobic Membrane Bioreactor Permeates

admin2018-10-25T19:55:16-04:00July 25th, 2016|

Municipal utilities spend considerable time, energy and chemicals to remove phosphorous and nitrogen compounds like ammonia and ammonium from municipal wastewaters. Removing these nutrients is expensive and often not commercially feasible; however, even in low concentrations phosphorous and nitrogen can degrade water quality. This 2013-2015 project created an effluent of specific, elevated, concentrated feedstock amenable [...]

Treatment of Vegetable Wash-Water to Permit Water Recycling

admin2018-07-18T20:18:18-04:00June 22nd, 2016|

The processing of fruit and vegetables requires high volumes of potable water and standards for wastewater being released into the municipal system have become more stringent. Little is known about the physical and chemical characteristics of wastewater derived from different processing operations, and subsequently which technologies are most effective for each crop type.

Managing Uncertainty in the Provision of Safe Drinking Water

admin2018-10-30T13:13:05-04:00April 27th, 2016|

This project deals with clarifying a common framework and approach to management options, one that can be used by providers and regulators to approach management choices and underpin their commitment to the central task of maintaining a vigilant focus on the following: How best can drinking water providers and their regulators address risk and uncertainty [...]

Assessing Pathogens in a Drinking Water Source: Investigations in the Grand River Watershed

admin2020-10-09T17:33:36-04:00April 21st, 2016|

Source water characterization is an important component in the multi-barrier protection of drinking water, and accurate data on pathogens is critical for treatment design, monitoring and risk assessment. This study determined pathogen loadings from the Grand River watershed and measured pathogen occurrence and concentrations in river water.

Creating a pipeline for emerging water testing technologies

admin2016-10-13T16:11:36-04:00April 15th, 2016|

Fecal contamination of water is currently assessed by culturing fecal indicator bacterial such as Escherichia coli (E. coli), because indicator organisms are simpler to detect than pathogens. However, these methods do not provide information about source contamination or the presence of microbial pathogens. The goal of this project was to narrow the gap in the [...]

Understanding and optimizing the performance of municipal waste stabilization ponds in the far North

admin2016-10-18T15:04:01-04:00April 15th, 2016|

Wastewater management in Canada’s Far North is challenging for many reasons: extreme cold climate, permafrost, short summers, remote locations, smaller populations and a shortage of skilled operators. Because of this, many communities use passive technologies like waste stabilization ponds — exclusively, or in combination with a wetland treatment area. This research examines existing treatment performance [...]

Pathogens in Bedrock Aquifers: A detailed study of the presence and transport of pathogens in urbanized settings with private bedrock wells

admin2016-10-14T12:42:32-04:00April 11th, 2016|

This study evaluated the occurrence of pathogens such as bacteria and human enteric viruses in bedrock aquifers across the country and explored the transport mechanisms that might have led to their presence. The results from this research are relevant for homeowners, public health authorities and provincial regulators.

Extending Municipal Water Demand Forecasting Capacities

admin2016-10-13T17:46:02-04:00March 14th, 2016|

Water suppliers run the risk of overestimating future demands unless they account for households' responsiveness to price changes and conservation measures. With the BROCKWATER program, planners working for small and medium size municipal water agencies have the capacity to account for households' behaviour when making water demand projections.

Building Capacity for Success: Towards watershed governance in British Columbia and beyond

admin2016-10-12T18:32:45-04:00March 14th, 2016|

With increasing pressures of population growth, pollution, and a changing climate, freshwater must be governed in new ways. This project focused on both identifying and beginning to address the key needs of government, rights holders, and stakeholders to help support the implementation of watershed-based decision-making across the country.

Tapping Into Consumers’ Perceptions of Health Risks in Municipal Water Supplies

admin2016-10-18T14:58:38-04:00February 25th, 2016|

Municipal drinking water systems in Canada undergo rigorous and frequent water quality testing and deliver high quality tap water to consumers. However, experts estimate that Canadians spend approximately $590 million a year on bottled water. This project tracked consumer perceptions of water quality and consumption choices in the Canadian context and examined trends over time [...]
