The Southern Idaho Regional Solid Waste District (SISW) is a special purpose unit of local government whose mission is managing solid wastes for the seven South-Central Idaho counties of Blaine, Cassia, Gooding, Jerome, Lincoln, Minidoka, and Twin Falls.
The SISW system currently features a state-of-the-art municipal solid waste landfill, fourteen waste transfer stations, a waste transportation system, a 3.9 MW landfill-gas-to-energy facility, an effective waste diversion system, a public information and education network, and a special waste management system for problem wastes.
To provide Southern Idaho with a safe, reliable, and efficient waste management system.
In 1991, Idaho legislature passed a law authorizing the formation of regional waste districts. In 1992, the Southern Idaho Regional Solid Waste District formed. Sites for the regional landfill were explored with input from the public. Construction at Milner Butte Landfill began in 1993 and opened for operation on April 6, 1994, four days ahead of federal mandate. In June of that year, work began to close and cap the seventeen county-owned landfills.
Since then, SISW has continued to add services to support proper waste disposal in Southern Idaho. The system currently features a state-of-the-art municipal solid waste landfill, fourteen waste transfer stations, a waste transportation system, a 3.9 MW landfill-gas-to-energy facility, an effective waste diversion system, a public information and education network, and a special waste management system for problem wastes.
