Caldwell, ID Trash & Recycling: Pickup Rules & Schedules (2026)

Caldwell residential trash collection is provided by Republic Services and billed on the resident's Caldwell City utility bill. Per the official residential guide, "trash and recycling must be set out by 7 a.m. with the lids closed," and trash should be bagged to prevent blowing during service. Each residence receives a 95-gallon trash cart for automated pickup, with additional carts available for an extra monthly fee. Weight limits are specific: 95-gallon carts are limited to 200 lbs, and extra trash cans must be 35 gallons or smaller and 60 lbs or less. Overflow may go in securely closed heavy-duty bags (1.5 mil or thicker) weighing 30 lbs or less. Used motor oil is accepted in clear 1-gallon jugs visible to the driver, up to 2 gallons per week. No tires, liquids, hazardous waste, or vehicle batteries may go in the trash cart - those route to the quarterly Household Hazardous Waste collection for Canyon County residents. Republic Services observes six holidays - New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day; during a holiday week, if your normal collection day falls on or after the holiday, collection is delayed by one day, while holidays on the weekend do not delay collection. For service starts, stops, or billing, residents contact Caldwell City Utility Billing at (208) 455-3000 ext. 1; for carts, Republic Services at (208) 466-3302.
