Yolo County Central Landfill - Davis, California Solid Waste Management Facility

Yolo County Central Landfill is a municipal solid waste landfill located in Davis, California, United States. It serves Yolo County and surrounding areas, operating under the regulatory oversight of the California Department of Resources Recycling and Recovery (CalRecycle) and the U.S. Environmental Protection Agency (EPA). As a landfill, it plays a key role in the region's waste management infrastructure. The facility operates under Subtitle D of the Resource Conservation and Recovery Act (RCRA), which governs municipal solid waste landfills, and complies with California's stringent landfill regulations, including methane gas collection and leachate management. The landfill likely employs modern liner and leachate collection systems to protect groundwater, and gas collection systems to capture methane for energy or flaring, reducing greenhouse gas emissions. Yolo County Central Landfill is a significant component of the county's waste management strategy, providing disposal capacity for residential, commercial, and industrial waste. Its location in California's Central Valley places it in an agricultural region with sensitive groundwater resources, making environmental safeguards critical. The facility contributes to local waste diversion goals and supports the circular economy through potential landfill gas-to-energy projects.

The landfill is situated in California's Central Valley, a region with intensive agriculture and a Mediterranean climate. Groundwater protection is a primary concern due to the area's reliance on aquifers for irrigation and drinking water. The facility must manage leachate to prevent contamination of local water resources. Methane emissions from decomposing waste are a key environmental factor; landfill gas collection systems help mitigate greenhouse gas emissions and can be used for energy generation. Proximity to Davis and other communities requires careful management of odor, traffic, and litter.
