There are numerous challenges with respect to the construction and operation of municipal infrastructure innorthern communities, including climate, remoteness, and capacity. Subsurface wastewater treatment systems,termed Rapid Infiltration Basins (RIBs) or Soil Aquifer Treatment (SATs) systems in several North Americanjurisdictions, could be an effective wastewater management alternative for small, remote, northerncommunities. Several communities already use a form of subsurface wastewater treatment in the CanadianNorth, but the performance and environmental risks associated with the practice in northern environments havenot been studied. This project will generate northern specific guidelines for both siting and designingsubsurface wastewater treatment systems in the Canadian North, and involves a strong partnership betweenDalhousie University and the key government agencies responsible for both the regulation and implementationof municipal wastewater treatment systems in the Northwest Territories. The research will involve detailedfield investigations of permafrost dynamics, groundwater flow and contaminant transport in northerncommunities using subsurface wastewater treatment systems. This information will be used to calibrate andvalidate new numerical models capable of simulating the performance of these types of systems under a varietyof environmental conditions, including a changing climate. This research project has the potential to generatenew wastewater management solutions that will help protect the health of northern and indigenous Canadiansand the environments they live in.

关于市政基础设施内在社区（包括气候，偏僻和能力）的建设和运营面临许多挑战。在北美几个北美朱丽室中，被称为快速渗透盆地（肋骨）或土壤含水层处理（SATS）系统的地下废水处理系统可能是小型，偏远，北部社区的有效废水管理替代方案。几个社区已经在加拿大北部使用了一种地下废水处理形式，但是研究了与北部环境中这种实践相关的性能和环境风险。该项目将生成北部的特定指南，以介绍加拿大北部的位置和DesigningSubsurface废水处理系统，并涉及牢固的合作伙伴关系，以及负责西北地区的Municipal Wastewater治疗系统的监管和实施的主要政府机构。这项研究将涉及使用地下废水处理系统对北部社区中多年冻土动态，地下水流量和污染物运输的详细研究。该信息将用于校准和估算新的数值模型，能够在多种环境条件下模拟这些类型的系统的性能，包括气候变化。该研究项目有可能引起废水管理解决方案，这些解决方案将有助于保护北部和原住民加拿大人的健康和他们所生活的环境。
