The Northern Alberta communities of Northern Sunrise County (NSC), the Village of Nampa, and Woodland Cree First Nation (WCFN) have formed a collaborative partnership to meet the future water needs of their communities on a regional basis. The project is to build a new energy efficient regional water system with the objective of delivering safe and reliable drinking water to a number of the farming communities, Hamlets, Village, and First Nations communities in the region. The new water system will include a raw water transmission line, Desilting Pond, Raw Water Reservoir, water treatment plant (WTP), and regional transmission line system.
By adopting an integrated design process that focuses on sustainable practices, water conservation, energy conservation and demand management into the design and operation, this facility has stepped far beyond the current industry practices with respect to the design and operations of water treatment plants currently or previously constructed. The stakeholders involved have adopted “Water for Life: Alberta's Strategy for Sustainability” and are committed to the wise management of Alberta's water.
This regional water system would eliminate two existing, outdated water treatment plants and provides the experienced operators required to maintain the water treatment system. The proposed water treatment plant site is in an undeveloped and very low density populated area. Key to the siting of the treatment plant is to maximize the use of existing water supply and transmission infrastructure. This reuse of existing infrastructure mitigates the negative impact of developing an undeveloped site. As further mitigation it is intended that the building footprint will be optimized and incorporate features to blend into the natural surroundings.
The proposed energy efficient measures integrated into the building design are targeted to achieve a total reduction of 45% (minimum of 40%) in energy consumption, relative to a reference building and based on the Model National Energy Code for Buildings (MNECB). The vision for the project includes reducing the environmental footprint of the project and maximizing the reuse of existing infrastructure, and advancing the knowledge of water conservation and environmental awareness within the communities.
Some of the key features of the water treatment plant include:
- LEED Silver Certification.
- A High Efficiency Heating System for the entire building.
- A Heat Recovery Ventilation System for the entire building.
- A High Efficiency Domestic Hot Water System for the administration building.
- A High Efficiency Cooling System based on a water-to-water heat pump system for the administration building.
- A Solar Pre-Heating of Ventilation Air for the process building.
- A Waste Heat Recovery to have the ability to supplement heating of the process building from the electrical generator.
- An automated lighting control system will be designed and specified with all areas lit with energy efficient lights, room occupancy sensors, continuous and staged dimming in response to day light intensity and on/off switches in the storage rooms.
- The incorporation of systems such as water-to-water heat pumps, heat recovery, solar energy, waste heat recovery and other proven technologies reduce or minimize the reliance on nonrenewable fuel and consequently the facility carbon footprint.
- Energy use reduction through enhanced building envelope insulation values, and triple glazed window units.
- Use of recycled or reused construction material.
- Energy demand management systems to control the operation time of pumps and other systems in order to reduce peak loading, which helps alleviate pressure off of the electrical grid.
- Intensive remote monitoring and control capabilities to continuously monitor the water treatment process, energy performance and minimize the requirements for operators to travel to site.
- Increase in treated water efficiency (percentage of final treated water compared to raw water extracted) of 90% compared to current industry design standards of 82%.
- Maximize the reuse of existing infrastructure including the existing intake at Peace River and 25 km of existing pipeline.Application Form GMF Call for Applications: Energy 2008
The NSC WTP will be a model example for Northern Alberta, as this will be the first LEED Silver water treatment plant in this region. The goal is to introduce sustainable design into the Northern Alberta region, to encourage sustainable development and energy efficient solutions, and be more familiar with the LEED system and thus capable of incorporating sustainable design in future capital projects.
Condition precedent to grant disbursement:
- That if the actual reduction in energy consumption is less than 40%, no grant will be awarded.
