The goal of this proposed Alliance partnership is to assess the value and feasibility of using stormwater outfall catchment bags to prevent floatable debris from entering the South Saskatchewan River through the City of Saskatoon's stormwater outfalls. These reusable bags have been used in other municipalities across North America to intercept floatable debris before it can enter receiving water bodies. If this proposed proof-of-concept study on two major outfalls is successful, the City of Saskatoon anticipates equipping most of its major outfalls with these bags. In addition to floatable debris, this research project will also establish methods and strategies to better understand the spatial and temporal emission dynamics of microparticulate contaminants (e.g., rubber tire and road wear particles, microplastics, brake abrasion dust) as well as dissolved contaminants that originate from these particulates. This research has the potential to lead to meaningful improvements of urban water quality for all Canadians.

联盟这一拟议伙伴关系的目标是评估使用雨水排放口集水袋防止可漂浮的碎片通过萨斯卡通市的雨水排放口进入南萨斯喀彻温河的价值和可行性。这些可重复使用的袋子已经在北美其他城市使用，在可漂浮的碎片进入接收水体之前将其拦截。如果这项拟议的关于两个主要排污口的概念验证研究成功，萨斯卡通市预计将在其大部分主要排污口配备这些袋子。除了可漂浮的碎片外，该研究项目还将建立方法和战略，以更好地了解微粒污染物(例如橡胶轮胎和道路磨损微粒、微塑料、刹车磨损粉尘)以及源自这些微粒的溶解污染物的空间和时间排放动力学。这项研究有可能为所有加拿大人带来有意义的城市水质改善。
