P@na Certification

Not that great of a pic, but shot this over the weekend in S.F. You can see the guy in the yellow jacket with a wand. Now where is this water going? You think down the storm drain and straight into the bay?

The most disturbing part was as we were comming up the stairs from the bart (subway) which is behind the truck. Us and about 200 other people had to walk within about 3 feet of this guy washing with hot water to get passed him and out to the street. Way to riskey for my liking. Infact I stoped cleaning 7eleven store fronts due to traffic at all hours of the night. I just knew sooner or later something bad was going to happen. Not worth it too me.

Nigel, I guess anything is possible. Maybe the rig came with their company name on it too? lol. :)

The PW company was pulling water off the spigot on the front of the building.
A construction company was pulling water off the hydrant and it was not leaking.

Some of the runoff was coming from the construction company. They had a guy inside the garage power washing parts of the garage with a wand on one floor while the striping guy was working the just dried floor above.

The runoff from the PW company was mixing with the construction company's runoff. The PW company was washing concrete dust off the decorative metal sides of the parking structure with a lift.

Don't get me wrong, I don't think they did anything illegal here. We have been in almost the exact same situation and the only thing we did differently was to put down gravity filtration before the drain trap sediment. A carbon filter would have taken care of the concrete dust easily enough and could have been thrown in the dumpster on the way out.

I just think its a little PW#A-esque to run all this dirt down the storm drain while filling your "wastewater" tank with tap water from the spigot. "DO AS I SAY, NOT AS I DO!" I think that is a quote from Al Gore or Obama. Are they org members?

And, oh yeah, like I said previously, that drain goes directly to Lake Mead.


Thanks Tony,

whats your setup for gravity filtration?

Was this new construction wash down or a used garage with oil spots?
 
This was new construction washdown.

For that situation I would use roll up three of the following into the shape of an "oil sock" or "boom" and tie them into that shape with wire:

1) polyester pre-screen - made from the same type of material Jerry uses for the base on the vacuberm

followed by

2) A finer polyester filter

followed by

3) A carbon filter

Total cost about $4

When done, toss in the trash.

This gravity filtration is the same as the more elaborate container filtration being sold at the world of Concrete for companies doing construction cleanup.

Where would you source materials for that price?

I dont think the carbon would be needed for new construction wash down

Too, blurry. Looks like a guy power washing while riding a bicycle...
