The Shepard Landfill in Calgary, Alberta, Canada, is a significant waste management facility that has been in operation since 1979. Located in the southeastern part of the city, the landfill has been a crucial component of Calgary's waste disposal infrastructure, serving a population of over 1.4 million people. The facility is owned and operated by the City of Calgary, which has implemented various strategies to minimize its environmental impact and maximize the landfill's lifespan.
History and Development of the Shepard Landfill
The Shepard Landfill was initially designed to accommodate the city’s growing waste management needs, with an expected lifespan of approximately 20 years. However, due to advancements in waste reduction and recycling programs, as well as improvements in landfill design and operation, the facility has exceeded its original lifespan. Over the years, the City of Calgary has implemented various upgrades and expansions to the landfill, including the addition of new cells, leachate collection systems, and gas management infrastructure.
Environmental Considerations and Mitigation Strategies
The Shepard Landfill has been designed and operated with environmental considerations in mind. The facility features a multilayer liner system to prevent leachate from contaminating groundwater, as well as a leachate collection and treatment system to minimize the risk of environmental harm. Additionally, the landfill is equipped with a gas collection system, which captures methane and other gases produced by decomposing waste, reducing greenhouse gas emissions and minimizing the risk of explosions. The City of Calgary has also implemented a comprehensive monitoring program to track the landfill’s environmental performance and identify areas for improvement.
