Solid Waste Facility
Central Contra Costa Solid Waste Authority
1850 Mt Diablo Blvd #320, Walnut Creek, CA 94596
(925) 906-1801Central Contra Costa Solid Waste Authority in Walnut Creek is the local place for household trash, recycling and yard debris drop-offs for residents and small haulers. It’s a solid waste facility that sees a steady stream of neighborhood pickups and truckloads during weekends and seasonal cleanups.
Pull up to an entrance booth where attendants direct traffic into lanes. There’s a scale and you’ll typically stop on the way out for weighing; traffic flows through several drop-off bays and containers. The site looks industrial-paved lots, concrete pads, and piles or large containers set off from the driving lanes. On busy days expect lines and trucks maneuvering slowly, so give extra time.
Facility Information
Before You Go
- Sort recyclables and organics at home first - California rules mean those are often handled separately and it speeds things up.
- Secure loose materials in the truck bed or cover with a tarp so nothing blows out while waiting in line.
- Avoid peak weekend windows if possible; early weekday mornings or late afternoons tend to move faster.
