Delta Diablo Household Hazardous Waste Facility

This place is amazing — period. Clean, professional, helpful, courteous. I stayed in the truck, they handled the paint cans and I drove off. I don’t know who is managing this facility, but they should run a few more businesses in the area because they do it right.
It can’t get much better than this. Really.

I came here to drop off a bunch of random nonsense I found in the backyard of my house. Previous owner was a contractor and he built up quite a collection of stuff. Bottom line, I did not read through the directions on the website: you can only drop off so much at a time, and even carrying it all together at once is a fineable offense of 25k.
The gentlemen here were kind enough to explain this to me, even though they could’ve let me have it. I would’ve deserved it for not reading the directions throughly. Anyway, they’re great, don’t make the same mistakes I did.

This place takes stuff that the dump doesnt take. Like paints, light bulbs and hazardous chemicals. Dont expect to throw a whole business’ amount of stuff here. Place takes only 15 gallons worth of material. Its only open from Thur-​Saturday 9am-​4pm. You will need your ID and items should be in your trunk or back of truck bed ready to take out by there staff. You dont even get out of your car. There friendly staff unloads all material for you. NO CHARGE– FREE DROP-​OFF site

Nice place. Kept well.

Note: Only open Thurs-​Sat 9am to 4pm
I went looking to write a review for this and found it as Delta Household Hazardous Waste Collection so now they have reviews under two different names.
Dispose of your waste properly. If you live in East Contra Costa county and have hazardous waste to dispose of this is the place to go.
We moved to Antioch a couple of years ago and, of course, it did not take us long to accumulate some waste we should not throw in the regular garbage. Fluorescent bulbs, batteries, the little non refillable propane cylinders and so on. Hunting for a place to dispose of them properly I found a phone number at the city and was directed to this place. Even with GPS we had a doozy of a time finding it but finally did. There were all sorts of buildings on our left (headed towards Pittsburg) and this place is on the right. It was a no fuss transaction. We filled out a wee form (did not have to detail what we were bringing, gave them our stuff and were on our way. They take old electronics, house paint, all sorts of stuff. I am sure there are things they will not take but call ahead and find out.

We take all of our old paint, used motor oil and e-​waste here it cost nothing to dispose of and you get to keep it out of the landfill.
Just pull up and the workers will unload it for you.
For safety and environmental reasons it is illegal to dispose of house hold hazardous waste in the garbage, sewers, or storm drains.
The facility is available to the residents of the following East Contra Costa County communities:
Antioch, Bay Point, Bethel Island, Brentwood, Byron, Discovery Bay, Knightsen, Oakley and Pittsburg. You will need to show proof of residency — such as a utility bill or driver’s license.
