9.5 Delivering clean water to students in the Himalayas through innovative partnerships

Presented By: Siobhan Holladay, Hatch Mott MacDonald.
Time: Tuesday, 10:20 - 10:50 AM

The Munsel-ling boarding school is located in the Spiti Valley, a desert mountain valley located in the northeastern part of the Indian State of Himachal Pradesh. This remote, high-altitude valley in the Himalayas has no access for more than seven months of the year due to snow on the high mountain passes. Since its foundation in 1996, the school has struggled to provide adequate safe drinking water; diarrheal disease is pervasive in the student population despite efforts to improve student health at the school. In 2006, the Munsel-ling school partnered with UBCs Global Health Initiative (GHI) – a student-led initiative that seeks to enhance global health education and provide hands-on skills training to UBC students. GHI also offers students the opportunity to participate in health projects across the globe.
Since partnering with Munsel-ling in 2006, GHI has worked to improve health at the school, but the supply of clean drinking water has remained an issue. In 2013, GHI partnered with Hatch Mott MacDonald (HMM), an engineering consulting company, to address drinking water supply, quality, and accessibility at the school. HMM offered the time and expertise of their Vancouver Water Team, who supported a team of senior engineering students from UBC in the design of a water system for the school. HMM provided guidance on hydraulic design, cold-weather conveyance, and drainage. The collaboration between the UBC engineering students and the HMM Water Team led to a more robust and durable design that was implemented in 2013.

9.6 Development of a framework for integrated resource recovery in the Vancouver sewerage area

Presented By: Mike Homenuke, Kerr Wood Leidal Associates Ltd.
Time: Tuesday, 10:50 – 11:20 AM

Metro Vancouver is committed to implementing resource recovery from liquid and solid waste streams, as part of its Integrated Liquid Waste and Resource Management Plan and its Integrated Solid Waste Management Plan. The first step towards "Integrated Resource Recovery" (IRR) is developing an IRR Framework that defines strategies, objectives, and timelines for potential resource recovery initiatives.
Metro Vancouver retained Kerr Wood Leidal, and its partners, Compass Resource Management and CH2M Hill to develop the IRR Framework for the Vancouver Sewerage Area. This project entailed compilation of potential resource supply and demand inventories, research on potentially technologies, consultation with stakeholders, and evaluation of a range of IRR opportunities, using a "structured decision making" approach. The study focused on liquid waste, solid waste, and energy as the major themes. Key objectives for IRR opportunities included reducing of greenhouse gas emissions, minimizing residuals from solid waste, introducing new and innovative technologies, and minimizing net lifecycle costs of waste management. The end result is an actionable series of projects and initiatives that Metro Vancouver can deploy to achieve these objectives over a 50-year period. These include district energy, anaerobic digestion of source separated organics, biosolids management, responsible use of wood waste as a heat source, and use of emerging technologies for resource recovery.

9.7 Achieving carbon neutrality through offsetting partnerships

Presented By: Dr. Steve Conrad, Simon Fraser University.
Time: Tuesday, 11:20 – 11:50 AM

Under the current BC Climate Action Charter, many water sector utilities are actively seeking ways to achieve carbon neutrality. In my presentation, I discuss and diagram the opportunities of greenhouse gas (GHG) reduction projects within the urban water cycle as well as discuss how partnering with offsetting companies could assist in funding these projects – especially considering the indications that the BC government is reducing or eliminating the Pacific Carbon Trust. My presentation quantifies the scales of opportunity for GHG reduction in terms of overall project cost and cost per tonne CO2 reduced. I then present how $/tonne reductions from GHG programs provides a market incentive for utilities to fund overall energy management programs. My presentation concludes by illustrating several project examples and providing a rough order of estimate of quantity and relative costs for GHG reductions for each.

15.4 Lions Gate secondary wastewater treatment plant: A presentation of the indicative design

Presented By: Paul Dufault, Metro Vancouver.
Time: Tuesday, 3:50 - 4:20 PM

As identified in Metro Vancouver's Integrated Liquid Waste and Resource Management Plan, the existing Lions Gate Primary Wastewater Treatment Plant, servicing the North Shore Communities of Metro Vancouver, will be replaced by a new secondary wastewater treatment plant by 2020. In upgrading the Lions Gate plant, Metro Vancouver embarked on an Integrative Design Process (IDP) that is proving to realize this project's potential to demonstrate Metro Vancouver's commitment to sustainability, provide leadership, and build a model wastewater treatment facility, while fulfilling its mandate of provision of a core service.

On November 15, 2013, the Metro Vancouver Board unanimously endorsed the Indicative Design for the new Lions Gate Secondary Wastewater Treatment Plant. The Indicative Design will be used as the basis for pursuing Senior Government Funding and the design and construction phase. The Indicative Design is the key outcome of the Project Definition Phase completed by Metro Vancouver. Grounded in the key project objectives, the Project Definition Phase has been guided by the IDP that brought together technical experts, community interests, and decision makers which expanded the potential of the Lions Gate Secondary Treatment Plant.

The indicative design considered many issues including visual aesthetics, odour control, truck traffic, noise, resiliency to sea-level rise and future adaptability, and costs to taxpayers. The configuration of the new plant is a compact and contextual addition to the diverse zoning in the neighbourhood. At a recent public meeting, 80% of the respondents felt that the plant design met the values of the community. Some of the design features include a translucent gallery to reduce the apparent height of the building from street level, extensive planting along the front facade, and a pedestrian scaled public entrance and outdoor open space. Odour control applies the principles of prevention by minimizing the release of odours, containment by physical covers, treatment by equipping with a two-stage odour treatment system, and dispersion by discharging treated air through a stack.

The presentation will provide an overview of the Indicative Design of the new facility. It will describe the recommended treatment technology, architectural character, and community integration opportunities and lay out the next steps in Metro Vancouver's approach for this new integrated facility.

15.5 City of Kamloops - Existing 600mm AC Forcemain Mapping

Presented By: Tim Ross, Pure Technologies
Time:  Tuesday, 4:20 – 4:50 PM

The City of Kamloops used Sahara technology to locate the horizontal and vertical position of 3 km of 600mm AC forcemain that serves a population of 46,000 people. The forcemain was installed in the 1970's and is now becoming a concern in terms of its age, capacity, and lack of redundancy.

The City’s intent is to twin the line with a 750 forcemain. However, without accurate as built records for the 600 forcemain, design of the new main was not possible. The City attempted a geophysical investigation using electromagnetic mapping tools, cable and pipe locator, and ground penetrating radar. Unfortunately, the results of the program were generally inconclusive. As a second attempt, the City undertook hydrovac excavation at critical locations. This was successful, but expensive and provided limited information.

The Sahara technology is a tethered leak and gas pocket detection tool for pipeline inspection. The main reason the tool was selected for this application was the ability to track its sensor head from above ground as it moved through the forcemain. In addition a new algorithm and tracking technique allowed for identifying the sensor head, and thus the pipe’s, depth below the surface. In this manner the forcemain was able to be mapped in X, Y, and Z coordinates.

The City has now completed design of the forcemain twin, and planning to begin construction in 2014. The project involves 3 km of 750mm diameter force main, ARVs, emergency pump connection chambers, crossing of Kinder Morgan transmission lines, and road restoration.
