Who We Are

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.
