About SISW

Southern Idaho Solid Waste (SISW) is a regional solid waste district that operates facilities in Blaine, Cassia, Gooding, Jerome, Lincoln, Minidoka, and Twin Falls Counties. SISW has utilized the Milner Butte Landfill and a network of fourteen waste transfer stations to provide environmentally friendly means of waste disposal since 1994. We offer municipal solid waste disposal, recycling, waste diversion, special waste disposal, and public education programs in an effort to be thoughtful stewards of our earth and maintain the beauty of Southern Idaho.
