The City and County of Denver owns the Denver Arapahoe Disposal Site (DADS) landfill, which is located at 3500 South Gun Club Road, Aurora, CO, just east of the intersection of Hampden Avenue and South Gun Club Road. DADS is a fully permitted subtitle D landfill and accepts municipal solid waste, construction and demolition debris, asbestos waste, and some types of industrial wastes such as coal-fired power plant fly ash and petroleum-contaminated soil.
The Division of Environmental Quality ensures that DADS operates in a manner consistent with state and federal regulations and in accordance to the operating agreement between the City and Waste Management of Colorado, Inc., who operates the landfill on the City’s behalf.
For questions concerning hours of operation, disposal costs, and disposal requirements at DADS, please call 720-876-2620. For questions concerning the management and acceptance of industrial wastes, please call 720-977-2102.
DADS is a part of a larger tract of land deeded to the City and County of Denver in the 1960s by the federal government for the purposes of public health. The initial landfill, Lowry, operated through 1990. In 1990, the DADS landfill began operations and continues to operate today as the largest landfill in Colorado and one of the largest in the country. DADS accepts on average 6,500 tons of waste per day or about 2 million tons per year.
Compatible and sustainable practices and services have been and continue to be incorporated into the DADS property. These uses are offered through the City and Waste Management, Waste Management only, or third parties. Over 7 million shredded tires that were collected during the 1960s and 1970s were used as tire-derived fuel in the early 2000s. The landfill gas to energy plant generates enough electricity to power about 2,000 homes per year. There is also a drop off area for household and some construction recyclable material, an area for concrete and asphalt recycling, and a composting facility.
The City and County of Denver encourages reduce, reuse, and recycling both within Denver and in the surrounding communities. Denver residents can obtain information concerning recycling and household hazardous waste services at Denver Recycles.
Additionally, recycling drop off of the following materials is available at DADS: Asphalt Shingles, Electronic Waste, Scrap Metal, Single Stream, White Goods, and Whole Tires. Fees apply to some material. Please call 720-876-2620 for details.
The City and County of Denver also encourages waste reduction through composting, whether through backyard composting, drop off programs, or contracted services.
Compostable material, such as food waste, yard clippings, and clean lumber, may also be taken to DADS for processing into compost product. Please call 720-876-2620 for fees and details.
The City and County of Denver and Waste Management are dedicated to ensuring that the landfill protects the environment by monitoring groundwater through a network of groundwater monitoring wells, operating a landfill gas collection system, and screening waste received to make sure that no regulated hazardous waste is landfilled. These are just a few of the environmental management efforts undertaken at DADS to protect the environment.
