Regina Research Alliance

From 2011 to 2023, the University of Regina carried out biennial random-dialed phone surveys to better understand the public’s perceptions of the Regina Police Service. The main areas of interest are: Public Information and Social Media, Visibility and Presence, Trust and Confidence, Crime and Fear of Crime, and Quality of Service. The survey represents one assessment tool as well as an opportunity for the public to provide feedback anonymously on a range of topics. Read more.

The lengthy purification process required to produce drinking-quality water also produces a large amount of sludge waste that is difficult and expensive to dispose of. Working with the Buffalo Pound Water Treatment Corporation – where both Regina and Moose Jaw get their water – Dr Xue’s team is creating useful products out of the sludge waste, saving money and helping the planet at the same time. One of those products is a lightweight, porous and highly absorptive ceramics-type material called ceramsite that can be used to remove pollutants from water. If that pollutant is phosphorous, for example, the ceramsite can then be sold as a landscape mulch where it will act as a slow-release fertilizer. Read more.

By integrating membrane filtration and biodegradation into one system, membrane bioreactors (MBRs) can achieve excellent treatment performance with very small footprint and reduced sludge production. Due to the high costs and complexity of MBRs using traditional membranes, dynamic membrane bioreactors (DMBR) have gained increasingly more attention from the research community.

Dynamic membranes (DMs) can be made with inexpensive materials, such as nylon and stainless-steel mesh. The deposition of solids and growth of microorganisms on the DMs will eventually form a dynamic cake-layer that can be equivalent to microfiltration (MF) or even ultrafiltration (UF) membranes. In our ongoing NSERC Alliance project, a granular sludge-DMBR (GS-DMBR) is being developed for sustainable wastewater treatment and reuse in the Canadian Prairie climate, in which we found that DMs are very promising but traditional DMs are challenging to be made in the laboratory with high quality, flexibility in design, and consistency.

In this application, we aim at fabricating inexpensive yet robust membranes by 3D-printing. The localized and global configuration of the membrane module will be designed to optimize the hydrodynamic conditions in the reactor and minimize fouling propensity. The outcomes of this project will not only benefit the partners but also be applicable to wastewaters in other sectors, such as food processing wastewater, and landfill leachate.

A research team led by professors at the University of Regina is drafting a roadmap that can inform and guide decisions about the EV infrastructure that will be required to support a net-zero transportation sector. A diverse group of researchers from the U of R’s Faculties of Engineering and Applied Science, and Business Administration – with expertise in transportation, smart grids, operations research, and renewable energy – will be working alongside specialists from SaskPower, the City of Regina, and Acuere Consulting Inc, an engineering consultancy.

With data provided by SaskPower and the City of Regina, the team will be investigating current traffic volumes and patterns to forecast demand for charging and how battery power will be consumed. They’ll be working to develop tools to help determine where charging stations should be located to support long-distance, east-west travel across Canada – by not only passenger vehicles but also commercial cargo trucks.

The team also wants to provide guidance on where to locate chargers in urban settings to prevent long lineups and congestion. Their aim is to create models that planners in government, municipalities, and utilities can use to anticipate charging needs down the road. Read more.

The University of Regina conducted a comprehensive fact- and evidence-based literature and research review covering both the technical aspect and the policy aspect of the issue. Within the technical review, topics included current regulatory environment related to non-agricultural uses; review of the status quo and potential alternative approaches; and, the technical impact of maintaining the status quo or adopting alternatives with respect to benefits and risks. From a policy perspective, the University conducted a jurisdictional review and examined the implications of maintaining the status quo, taking action to ban or restrict, and adopting an alternative, integrated pest management approach.

Novel wastewater treatment technologies are needed to address the weaknesses of current techniques, and ensure the sustainability of wastewater treatment in the future. In the context of circular economy, conventional wastewater treatment technologies are no longer adequate because of high energy demand, large sludge production, green-house gas (GHG) emissions, inability to remove emerging pollutants (such as microplastics and antibiotics), and poor cold-temperature performance.

On the other hand, wastewater can be a valuable resource if technologies were available to cost-effectively extract the water resources, nutrients, and energy contained in it. In recognition of the challenges and opportunities in wastewater, the City of Regina has been seeking future-ready wastewater management strategies that can bring co-benefits. In this project, we will develop a novel granular sludge-dynamic membrane bioreactor (GS-DMBR) system for wastewater treatment in the Canadian Prairies climate. The removal of representative emerging pollutants (such as microplastics) will be optimized; resource recovery (such as clean water resources) will also be explored. Insights in the governing mechanisms will be established by using numerical and statistical tools.

The system configuration and operating scheme will be improved based on the wastewater quality and seasonality variations. We think the novel GS-DMBR technology will consume less energy, produce less sludge, emit less GHGs, and remove emerging pollutants more effectively in the Canadian context. The outcomes will not only benefit the partners, the City of Regina and QuantWave Technologies Inc., but also shed light onto sustainable wastewater management in Canada and internationally.

The digital library search interfaces offered by public libraries are often designed to maximize simplicity, supporting look-up tasks when searchers know precisely what they need (e.g., the exact name of a book). While such approaches may support the simple search tactics needed to find a specific item in the library, they provide little support when the search task is complex. Complex search tasks are characterized by ambiguity and uncertainty, may be multi-faceted, and could stem from complexity in the source information itself.

For example, a public library searcher may wish to find books on the history of western expansion in Canada, without knowing much else about the topic or how it relates to other political events such as the North-West Rebellion. In such cases, exploratory browsing may allow the searcher to learn about the topic, followed by focused searching to find supporting resources. Without features in the search interface to enable such exploratory search activities, the success of the search depends on the abilities and experience of the searcher.

The primary goals in this research are to (G1) develop a deeper understanding of the information seeking behaviour of public library patrons, (G2) design, implement, and study new visualization-enhanced approaches for digital library search interfaces that support exploratory search behaviours in both stationary and mobile device use, and (G3) study how the context of the search (in the library vs. out of the library; stationary vs. mobile device use) can be leveraged to more effectively assist the exploratory search behaviour of public library patrons. A new breed of public library search interface will be developed that uses interactive information visualization to support and enhance the exploratory search needs of public library patrons, enabling them to more readily find the information they are seeking.

A deviation in the production of municipal solid waste has been observed in the City of Regina since the beginning of the COVID-19 pandemic began, and during the time control measures were put into place by the City and the Government of Saskatchewan. The change in waste generation rates could begin to impact the daily operation of the City's municipal waste collection and disposal service, as well as the safety of the solid waste collections and operations staff. Proper waste collection and disposal is vital to health and safety of the residents at any time, let alone during the COVID-19 pandemic.

Our municipal partner states that the elevated waste quantities has slowly begun to impact the revenue stream in the past few weeks. The goals of the project are to (i) conduct temporal analysis of municipal waste generation before and during the outbreak, and (ii) develop various scenarios and generate different forecast models for waste generation during and after the outbreak. Accurate waste data forecast helps the city to better manage its budgetary resources and plans their collection and disposal services accordingly. The proposed models will also be used to estimate the demand of the sanitation workers' personal protective wears. It is believed that the said simulation models will be useful to other cities and towns of similar socio-economic conditions as Regina.

No tool is currently available to forecast waste generation during and after a pandemic, and we would like to work with City of Regina team to fill the gap in literature. The proposed models will be of great benefit to the City in maintaining its leadership in sustainable waste management and evidence-based waste policy. It is also of interest to the City to assist in the growth of this market segment, both within Canada and abroad. Read more.

Public safety personnel (PSP), including municipal police and firefighters, are frequently exposed to potentially psychologically traumatic events. Such events contribute to substantial and growing challenges from posttraumatic stress injuries (PTSIs), including but not limited to posttraumatic stress disorder. This project involved implementation, testing, and continuous improvement of a set of evidence-based tools and training originally designed for the RCMP and adapted for a more diverse set of PSP. The objective of the tools and training is to protect PSP mental health. Read more.

This research project contributes to filling current gaps in fire data by undertaking primary research into the incidence, circumstances and risk factors of careless cooking in the City of Regina, with a focus on high risk populations. The impetus behind this research project came from Regina Fire & Protective Services (RFPS). Careless cooking has been the number one cause of residential fires in Regina for seven years, and has become a significant threat to public safety. Careless cooking incidents have been increasing each year, a growing trend the fire department is working to curtail. Read more.

The City of Regina is looking for ways to handle fats, oils and grease (FOG) that are disposed of into the wastewater system or removed from local businesses. The FOGs are notoriously difficult to manage due to their complex chemical makeup either individually or when combined. This study attempts to determine if the FOGs from wastewater and food establishment collected by the City can be converted into biodiesel.
