Ready-Mix Truck Washout: A Concrete Washout System for Your Job Site
CleanSite puts a watertight washout container on your job site so ready-mix drivers can rinse their chutes before they leave. When it’s getting full, you call and we pick it up.
- EPA, NPDES and BMP compliant
- Delivery, pick-up and disposal handled
- Containers and pans from 1.5 to 9 cubic yards
Where do the concrete mixer trucks wash out?
Every load of ready-mixed concrete leaves cement and rock in the chute. It has to be washed off before the mixer leaves, and without a set spot, washout ends up in the soil, the road or a storm drain. That’s how sites get written up and overtime starts.
A CleanSite container is that designated spot. Drivers back up, rinse the chute, and go.
Chute washout, step by step
- We set the container near the pour, where trucks can back up without blocking it.
- Each driver discharges the load, then rinses the chute and hopper into the container.
- Solids settle inside and the water stays contained.
- When it’s close to full, call 845-781-4-PAN and we’ll pick it up.

Picking a container for your ready-mix pour
How fast a container fills depends on how much concrete is left in each drum, so we size it with you. The water side adds up slowly. The hardened solids are what fill a container.
- A single pour or a tight lot: a 1.5 or 2.5 yard pan.
- Steady truck traffic over several days: a 6 yard container.
- Large sites and heavy pour schedules: a 9 yard container, or two side by side so trucks aren’t waiting.
Tell us the yardage and how many trucks you’re expecting, and we’ll match the size. More in what size washout container you need.
Why washout material has to be managed on site
Back at the plant, many ready-mix producers run reclaim and recovery equipment that separates sand and rock from returned concrete so it can be reused. A construction site has no reclaimer. The washout material has to be contained where it’s generated, then hauled off.
That’s the job of a washout container. Wash water and cement stay in the container instead of soaking into the soil, the solids harden, and CleanSite hauls the whole load away. Some contractors pay for “scrape and go” so drivers wash out at the plant instead; a container on site lets them wash out properly before they return, which cuts that cost.
What a washout container saves on a ready-mix pour
Truck time
Drivers don’t waste time searching for a dump spot, which means fewer overtime charges from the ready-mix supplier.
No “scrape and go” fees
Without a washout, some contractors pay extra for drivers to scrape the chute and wash out back at the plant. A container on site avoids that.
A clean site
No slurry concrete in the dirt, on the road or in the lawn you’ll be landscaping later.
Pouring with a pump as well?
If trucks feed a concrete pump, the hopper needs a clean-out at the end of the day too, and that’s more material at once. See concrete pump truck washout for the pan that fits under the hopper.
Ready-mix washout FAQ
Where do concrete trucks wash out?
On a well-run site, in a designated washout area such as a watertight container. Rinsing into the ground, the street or a drain breaks stormwater permits.
Is it legal for a concrete truck to wash out on site?
Yes, into a proper washout. New York’s construction permit bans washout water as a discharge, so it has to be caught and contained.
How much water does a chute washout use?
Not much: a chute rinse is a short spray. The leftover concrete is what fills the container, so call with the expected yardage and we’ll size it.
Can more than one truck wash out at once?
Yes, with two containers side by side. That keeps trucks from waiting in line on a big pour.
