I try to give you more explanations.

When you careen a vessel on the land with a brush and a karcher for
example, you produce wastewater which contain solvant, antifouling,
metals...

This wastewater is very polluant for the marina sea.
So I would like to know if it exists systems to collect, treat this
wastewater before it flow in the sea or the river.
And where can we see examples of this systems which respect the
environment in the world ?

Ahhhh... now I get it.
He wants to know about holding and treating waste water accumulated after
pressure washing the hull.
He was translating to English as opposed to American.

Interesting, however I didn't realize that the water was washing off "bad"
stuff. Did you guys know this? Is it normal to have a capture system for the
runoff?

Jesus, is there anything I do that isn't trashing the environment?

Antifouling paint is poisonous after all.

Yes.

In some places it's mandatory.

Hell, in CA it's my understanding that the residue and scrapings from varnish
removal have to be collected and disposed of properly.

We just mix it up with all the waste mercury and arsenic and dump it in a
lake. That way it doesn't pollute the ocean.

Do a search for waste recovery systems in regard to shipyards.

Here is an example of treating and recycling the water used to clean hulls.
