Can you actually catch them if they don't "'fess up", though?

When I drove one summer while in high school for a local mix service
here (classmate's Dad owned the place) there would have been no way to
prove it as they, at least, weren't monitoring onboard water
consumption...I suppose w/ "real" construction, that's done now.

(Note--Otto only let us kids deliver to the oil well sites where you
couldn't mess anything up other than bury it to the axles in mud... :) )

Well, if I have a delivery ticket that says no water was
added, and the test breaks at 2800 for a 3500 PSI concrete,
who is responsible? The plant! That is what I am talking
about. If you order 3500 PSI mix and you don't get it, it is
the cement plant that has to fix it.

That surely, is the "proof"...I was just curious during the
finger-pointing phase if the driver tried the "not me!" trick whether
with newer mix trucks water usage might be monitored...

One way to do that is to tell the plant that you want the
water tanks full when they arrive at the jobsite. That leaves
the driver the option of adding water and then stopping
somewhere and refilling the tanks, but I don't think that they
are that devious. Most drivers I have found to be pretty
honest. I can't imagine a situation where one would want to
ruin your mix just to be mean. Especially when they know that
their jobs could be on the line for it.

You can also check the level of the water tank on the truck
when it arrives and when it leaves, keeping in mind that if
the truck is not on level ground, the readings could be
different if it moves.

And if it needs to be 'pumped', I guess the slump is less, right ..so it can
flow thru the pump easier ?
