Solid Waste Information System (SWIS)

The Solid Waste Information System (SWIS) facility database contains information on solid waste facilities, operations, and disposal sites throughout the State of California. The types of facilities found in this database include landfills, transfer stations, material recovery facilities, composting sites, transformation facilities, waste tire sites, and closed disposal sites.

For each facility, the database contains information about location, owner, operator, facility type, regulatory and operational status, authorized waste types, local enforcement agency and inspection and enforcement records.

The data in the facility database is continuously updated and the downloadable data file is updated every Monday, Wednesday, and Friday at 6:00 a.m. Inspection and Enforcement Records should be current to the last quarter.
