Halifax Water – Integrated Resource Plan Page 5 TERMS OF REFERENCE summarizing the available options, Halifax Water will identify regulatory constraints, environmental impacts, and both capital and operating costs associated with each set of options. The supply-side assessment may include but not be limited to the following technologies and methods: Water Wastewater Stormwater • CSO / SSO management • Optimize number and configuration of pumping stations • Over-sizing pipes / storage • System optimization and flow routing • Optimize power requirements • Additional treatment capacity or upgrades • Regulatory upgrades • Receiving water quality • Strategic land management • Enhanced redundancy and optimization routing • Leak detection surveys • Leak reduction program • Master meter calibration • Water Treatment Plant operational uses • Additional treatment capacity or upgrades • Transmission main upgrades • Source protection • Strategic land management • On-site reduction of runoff • Optimization of drainage paths / corridors • Retention / storage • System optimization and flow routing • Deep storm sewer installation • Receiving water quality • Strategic land management 4.2.3 Demand-side Options Halifax Water will investigate demand-side management options through the IRP to reduce finished water requirements and wastewater flows. Demand-side assessment will include cost, supply and capacity needs, and usage impacts. The demand-side assessment may include but not be limited to the following technologies and methods: Water Wastewater Stormwater • I/I reduction (illegal connections, crossconnections, storage, retention, water movement optimization, etc) • Water recycling • Rate incentives • Lateral repairs • Source control • Construction standards • Customer leak reduction • Service meter calibration • Non-revenue water • Water conservation (outdoor water use reductions, xeriscaping, plumbing code modifications, water audits, etc) • Rate incentives • Grading requirements • Comprehensive controlled drainage management • Source control • Sediment / erosion management • Storm water rate structure • Construction standards G:\Engineering Dept\Common\Capital Projects - ACTIVE\Integrated Resource Plan 2011 - 6-495\Task 1.0 Terms Of Reference\IRP - Terms Of Reference V12.Docx October 31 2012 Page 142 of 272
Halifax Water – Integrated Resource Plan Page 6 TERMS OF REFERENCE 4.2.4 Screening of Supply & Demand-side Options Where possible, Halifax Water will establish performance metrics for the supply-side and demand-side options. The options will undergo a screening test to determine whether they will advance to more detailed analysis as part of the resource plans. The screening will focus on: • System optimization; • System reliability; • Redundancy and flexibility; • Feasibility; • Regulatory compliance; • Need and ability to obtain regulatory approval; • Total cost. 4.2.5 Financial Considerations Several financial considerations will be explored in developing the various resource plans including, but not limited to: • Impacts of declining water usage on rates and the revenue stream. • Availability of funding assistance through federal and provincial programs. • Timing impact of capital plan implementation (effect on budgets). • Using rates to incent ratepayers to use conservation technologies and methods. • Appropriate debt policy, in coordination with the UARB-approved Debt Study (underway with completion date of October 2012). • Costs associated with additional staff, information needs, tools, and technology to support capital program growth. 4.2.6 Basic Assumptions and Plan Considerations Halifax Water will identify the basic assumptions used for supply-side and demand-side options and system impacts related to aging infrastructure, capacity issues, regulatory compliance, and growth. These will be documented together with the proposed resource plans. Assumptions on the appropriate level of reinvestment by each asset class will be developed and documented. Options may include conventional dig and replace as well as in-situ repairs and lining and other trenchless techniques. Opportunities to rationalize operational practices will be explored. As a result of the Canadian Councils of Ministers of the Environment (CCME) Wastewater Strategy, new federal regulations are expected to be available in DRAFT form in the summer of 2011. Early indications are that the regulations will come into force sometime in 2012. The IRP will identify system and facility upgrades needed to comply with the new regulations. Halifax Water follows a “cost-causer” approach to asset construction. In general, the development industry pays for and installs assets related to growth.
