Transportation and Public Works is now Sonoma Public Infrastructure - Website updates coming soon!
Integrated Waste is a division of the Sonoma County Department of Transportation & Public Works (TPW). Our mission is to provide ecological solutions to solid waste disposal, natural gas recovery, electrical generation, recycling, and community hazardous waste disposal.
What we do
The TPW Integrated Waste Division owns the Sonoma County Central Landfill, which houses facilities for recycling, material reuse and natural gas and electrical generation. It owns five refuse transfer stations, oversees the regulation of two commercial hauling companies and maintains closed landfills.
Republic Services of Sonoma County, Inc. operates a large central landfill, located outside of Petaluma as well as four smaller transfer stations, located in Annapolis, Guerneville, Healdsburg, and Sonoma. See More
Reuse and Recycling Center
Recyclables such as scrap metal, cardboard, glass, metal and plastic containers, and newspaper can be conveniently unloaded at the recycling drop-off center, located at the Central Landfill on Mecham Road outside of Petaluma. See More
Household Toxics Disposal
Natural Gas Recovery
With nearly 24 million cubic yards of solid waste in place, the Central Disposal Site produces about 2,500 standard cubic feet/minute (scfm) of landfill gas. This gas is collected from 150 collection wells and transported through 4 miles of pipeline to the landfill gas-to-electricity facility and to the landfill gas-to-vehicle fuel pilot project. See More
Recyclable wood can be dropped off at any of the County Disposal Sites for a significantly lower cost than disposing of garbage. For disposal locations and hours of operation, please see Disposal Sites.
