Water, energy, and affordability: Key drivers in the financially sustainable management of urban water infrastructure

申请者提议为在安大略省内实施旨在保障市政供水的各种立法所需的知识库作出贡献。其中包括：2002年《安全饮水法》；规定财务自给自足的安大略省第453/07号条例；要求报告有形资本资产和折旧的PSAB 3150；以及2010年《水机会和保护法》，其中要求市政当局制定资产管理计划、财务计划、节水计划、风险管理计划以及绩效指标和目标，以管理其水利基础设施。拟议的研究将侧重于开发三个不同级别的水利基础设施资产管理系统。首先，申请人当前版本的战略规划模型将得到改进，将自来水和废水处理厂的运营包括到现有的自来水和卫生下水道网络，以获取向分水岭内的城市中心居民提供水和废水服务所需的能源消耗和总系统成本，并隐含地理解水是节约的和有限的。第二，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危害性指标制定关于水利基础设施的资本和运营支出的决定。具体而言，输水系统的性能指标可能表明，相对于新建筑费用的增加，修复现有破损的管道可以可靠地延长管网非关键区域的使用寿命。第三，将开发一个业务规划模型，作为申请者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。运行模型将涉及在水文模型中插入自来水、卫生和雨水下水道管道，并模拟它们与分水岭内水平衡的相互作用。该模式将得到推广，并适用于其他地方。

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.
