项目摘要

Stormwater is rainfall and snowmelt that runs off land into separate storm sewer (separated from sewage) orcombined sewer systems (potentially mixed with sewage). Urbanization has decreased quality and increasedquantity of stormwater runoff, negatively impacting receiving waters while often overwhelming existingmunicipal sewer infrastructure. Municipal stormwater management options include source control (controllingrelease into sewers), collection and conveyance (sewers); and end-of-pipe (treated/untreated). In terms ofquality, stormwater has high concentrations of pollutants such as nitrogen, phosphorus, organic matter,bacteria, viruses, metals, oil, grease, salts, etc. In terms of quantity, stormwater management is complicatedgiven the impacts of climate change with increased precipitation leading to sewer waters backing up ontoroadways and into homes/businesses, creating traffic problems and financial/insurance issues. As well,exposure to these potentially toxic waters poses a human and environmental health risk.Overall, research is needed to help improve the stormwater management and treatment infrastructure inSaskatchewan and the rest of Canada. Particularly, research is needed to create economically viable solutions toprovide at least primary treatment (settling of solids) for separate stormwater sewers prior to its release into thereceiving environment. The City of Sasktoon (City) is the largest municipality in Saskatchewan with separatedstormwater sewers with over 100 outfalls, many being directed without treatment to the South SaskatchewanRiver (SSR). The City acknowledges the need to better understand the impacts of these outfalls on the SSR andto identify the key outfalls to focus on for future infrastructure improvements. It is expected that regulationswill eventually be passed that will create the need for stormwater treatment, thus, this research project objectiveis to determine the impacts of stormwater outfalls on the SSR and to assess the potential for improved Citymunicipal stormwater management in anticipation of these regulations.

雨水是降雨和融雪，可从陆地上流入单独的雨水下水道（与污水分离）或弯曲的下水道系统（可能与污水混合）。城市化降低了雨水径流的质量和增加，对接收水的负面影响，同时经常压倒了现有的基础下水道基础设施。市政雨水管理选项包括来源控制（控制下水道），收集和输送（下水道）；和管结束（经过处理/未经处理）。就质量而言，雨水具有高浓度的污染物，例如氮，磷，有机物质，细菌，病毒，金属，金属，油，油脂，盐等。在数量上，雨水管理是复杂的，使气候变化的影响复杂，导致降水量增加，导致下水道的降水量增加，导致下水道往返往返机构和企业和企业和企业和企业和企业，以及问题和企业和企业，并造成流动和企业和企业和企业和企业，并处于问题和企业中。同样，接触这些潜在的有毒水域也带来了人类和环境健康的风险。除此之外，需要进行研究以帮助改善雨水管理和治疗基础设施Insaskatchewan和加拿大其他地区。特别是，需要进行研究以创建经济可行的解决方案，至少在将雨水下水道释放到其他环境之前，至少是主要的治疗方法（固体结算）。萨斯顿市（城市）是萨斯喀彻温省最大的市政当局，分别是施托式水的下水道，其中有100多个排放量，许多人无需对南萨斯喀彻温省（South Saskatchewanriver）（SSR）进行治疗。该市承认有必要更好地理解这些排放量对SSR的影响，并确定关键的排放量，以专注于未来的基础设施改进。预计最终将通过法规，这将产生雨水处理的需求，因此，该研究项目目标是确定雨水排放对SSR的影响，并评估改善CityMunicipal雨水管理的潜力，以预期这些法规。
