Shell Park Place is located on Macdonald Island in Fort McMurray, Alberta, Canada at the junction of the Snye, Athabasca and Clearwater Rivers. It is currently home to a sports complex that contains three (3) ice arenas, twelve (12) curling rinks, a fitness center, golf course, and an Olympic size swimming pool. Wastewater is conveyed via gravity sewer across the Snye River to downtown Fort McMurray where it is transported via a lift station and force main to an existing centralized treatment plant located on the west bank of the Athabasca. The Macdonald Island golf course receives its irrigation water from the Snye and Clearwater Rivers and uses an average of 20 million gallons (75,708 m3) through the season from May to September. Plans to expand the sports complex, referred to as Shell Place, include an additional football, soccer, and baseball stadium with capacity for 9,000 spectators along with a proposed 200-unit hotel. Projected wastewater demands for this recreational development exceed the capacity of the existing centralized collection system and would have required directional drilling improvements under the Snye River.
Initial upgrade plans required significant upgrades to the municipal sewer and water system for the increased capacity. The TITUS Platform returns 2570 MWh of thermal energy back to the pool and 20 million gallons per year reduction in water supply requirements. Reclaimed water is used for golf course irrigation and toilet flush water in the future hotel.
This project represents the first integration of direct water reuse with a TITUS District Energy Sharing System (DESS). Services include detail design, permitting, fabrication, delivery, installation and commissioning. This project reduced capital expense by $9M as compared to the conventional wastewater approach while also allowing for water and energy recovery.
This distributed water treatment and recycling system with heat recovery for MacDonald Island reduces total indoor potable water use by approximately 30% (50% for the proposed hotel) and reduce wastewater flow to the centralized facilities by nearly 100%. In addition, diversion from the Snye and Clearwater Rivers for golf course irrigation will also be reduced by up to 100% by utilizing reclaimed water. This will increase stream flow within the Snye River which is reported to have environmental concerns with decreasing flow. Energy will be recovered from the treated water before reuse and will be used to heat the indoor pool facilities. The peak energy recovery from the treated water heat system is estimated to be 240kW. The integrated ice plant refrigeration heat recovery is estimated to peak at 263kW, displacing a total of 2,570 MWh and resulting in a reduction of 605 tCO2e greenhouse gas emissions for RMWB.
The project provides the lowest impact design and construction while supporting the regions intent for low energy and low emissions, to demonstrate world leading sustainable operations in the region. Additional goals include minimizing the Life Cycle Cost for the combined water-energy systems considering district energy and direct water reuse systems.
Triple Bottom Line Impacts
- Reduce indoor potable water use by 30%
- Reduce wastewater flow to grid by nearly 100%
- Utilize 100% reclaimed water for golf course irrigation
- Reduce surface water diversions by 20 MGal per year
- Recover 240kW of wastewater heat energy
- Reduce 605 tCO2e greenhouse gas emissions
- Reduce capital expense by $3M
Shell Place Park is yet another example of Fort McMurray's sustainable leadership.
