The applicants propose to contribute to the knowledge-base require to implement a variety of legislation within the Province Ontario designed to safeguard municipal water supply. These include: the Safe Drinking Water Act 2002; Ontario Regulation 453/07 dictating financial self-sustainability; PSAB 3150 which requires reporting and depreciation of tangible capital assets; and, the Water Opportunities and Conservation Act 2010 which requires municipalities to develop an asset management plan, financial plan, water conservation plan, risk management plan, and performance indicators and targets to manage their water infrastructure. The proposed research will focus on developing three distinct levels of a water infrastructure asset management system. First, the current version of the applicants' strategic planning model will be enhanced to include the operation of water and wastewater treatment plants to the existing watermain and sanitary sewer networks in order to capture energy consumption and total system costs required to provide water and wastewater services to the residents of an urban center within a watershed, with an implicit understanding that water is conserved and finite in quantity. Second, a new tactical planning model will be developed that will enable the strategic model to enact decisions regarding capital and operational expenditures on the water infrastructure based on reliability and criticality metrics. Specifically, performance indicators for the water conveyance system might suggest that rehabilitation of existing deteriorated pipes may reliably extend their service life in non-critical areas of the network, relative to the increased expense of new construction. Third, an operational planning model will be developed as a continuation of the applicants' hydrologic model of the groundwater and surface water components of the Laurel Creek watershed. The operational model will involve inserting the watermain, sanitary, and storm sewer pipes within the hydrologic model and simulating their interaction with the water balance within the watershed. This model will be generalized and made adaptable to other localities.

申请人建议为安大略省实施旨在保障市政供水的各种立法所需的知识库做出贡献。其中包括：《2002年安全饮用水法》;规定财务自我维持能力的安大略第453/07号条例;要求报告和折旧有形资本资产的PSAB 3150; 2010年《水资源机会和保护法》要求市政当局制定资产管理计划、财务计划、水资源保护计划、风险管理计划，以及管理其水基础设施的业绩指标和目标。拟议的研究将侧重于开发三个不同层次的水利基础设施资产管理系统。首先，申请人的战略规划模型的当前版本将被增强，以包括水和废水处理厂对现有水管和卫生下水道网络的操作，以便捕获向流域内的城市中心的居民提供水和废水服务所需的能量消耗和总系统成本，其中隐含地理解水是守恒的并且数量有限。其次，将开发一个新的战术规划模型，使战略模型能够根据可靠性和关键性指标制定有关水基础设施资本和运营支出的决策。具体来说，输水系统的性能指标可能表明，相对于新建设费用的增加，修复现有老化管道可以可靠地延长其在网络非关键区域的使用寿命。第三，将开发一个业务规划模型，作为申请人关于月桂溪流域地下水和地表水组成部分的水文模型的延续。运行模型将包括在水文模型中插入供水干管、卫生管和雨水管，并模拟它们与流域内水平衡的相互作用。这一模式将得到推广，并适用于其他地区。
