Ada County Landfill


You are invited to attend an Open House at the Ada County Landfill main office at 10300 N. Seamans Gulch Road from 4:00 p.m. to 7:00 pm on September 17, 2019 to learn about a 3-year pilot study recently approved by the Boise District Department of Environmental Quality for recirculating landfill leachate in the North Ravine Cell (NRC). The pilot study will recirculate the leachate water back into the cell waste primarily as a means of reducing the amount of leachate stored in two evaporation ponds adjacent to the cell.


The pilot study is being conducted to gather data and monitor the effects of leachate recirculation on landfill gas production, landfill settlement, odors and other surface emissions, and the ability to reduce the amount of stored leachate in the evaporation ponds. Recent changes in waste water treatment plant discharge requirements are restricting disposal of leachate for treatment at the plants.


With that option no longer available, leachate recirculation into the waste is a method of disposal that is allowed by federal and state code and rules. Because it has never been done at Ada County Landfill before, the public open house is being offered as a way for the public to learn more about the process. If you have any questions regarding the open house, or the leachate recirculation pilot study please email, or call 208-577-4725.



The Ada County Landfill seeks to pro-actively manage County waste disposal facilities, enforce applicable codes, and provide reasonably priced and environmentally acceptable methods for solid and hazardous wastes reduction and disposal for County residents and businesses.

The services provided by the 2,700-acre multi-use Ada County Landfill Complex include:

  • Maintenance of a sanitary landfill for acceptance of solid wastes generated by Ada County residents
  • Operation of a permanent year-round facility for disposal of household and small business hazardous wastes
  • Contractual oversight of the franchised trash collection in unincorporated Ada County ensuring compliance with trash pick up, recycling and rates
  • On-site recycling programs for wood, tires, automotive batteries, refrigerators, and air conditioner.
  • Educational resource for local schools and service groups



SWAC is composed of a representative of each city municipality. These representatives are nominated by their city’s Mayor and City Council for review by the BOCC (Board of Commissioners). SWAC provides input to the Board of Commissioners on items dealing with Solid Waste, Hazardous Waste, Recycling and Diversion Programs. As part of the determination for less waste in the community, SWAC meetings will be as waste free as possible. This will include all agendas and minutes to be sent electronically to eliminate the need for paper products.
