The City of Modesto contracts with Gilton Solid Waste Management and Bertolotti Disposal Service for all garbage and recycling collection services. Each company has an exclusive service area as deemed by the Modesto City Council, thus your garbage company is determined by which street you live on.
Gilton Solid Waste uses a "1-pass" truck system, meaning the same truck picks up the garbage can and the yard waste can. The truck is divided internally to keep the materials separate, note the 2 doors on the backview below. Bertolotti Disposal Service uses 1 truck for the black garbage can and 1 for the green yard waste can.
