Dense earth has a 'standard' weight of 3375 pounds per yard. This
is immaterial, because it won't be dense when it's on the truck. The
numbers you need are these:
Earth, dry, excavated: 2016 pounds per yard
Earth, moist, excavated: 2430 pounds per yard
Sand, loose, 2430 pounds per yard.
For the 'truckload' guy, ask him how much is in a truckload.
As for the size of the tank, 10 x 6 x 6 = 360 cubic feet
360 * 0.03704 = 13.3 cubic yards.
As a cross-check, 1000 gallons / 201.974 = 5 cubic yards.
Hmmm.... Something's fishy, here. Are you sure about the size of
the tank? Were those *inside* dimensions, or *outside* dimensions
that you gave? I would have expected some headspace, but not *that*
much. Even if the tank is only 5 feet deep that's still 11 yards, and
I wouldn't expect over 50% headspace. Anyway, if the tank is really
10'x6'x6' internal size, then that's 13.3 cubic yards or around 29,260
pounds of dirt. That's quite a bit. So around 15 tons of dirt to
fill the sucker up. Dump trucks come in various sizes, but the most
common sizes around here are 5 and 10 yard dumpers, so you'll probably
need two trucks, unless somebody's got a 15 yard dumper or a 10 yard
with a 5 yard pony that will fit on your property and can do the job.
Make sure you specify what you need done... they expect to just dump
the stuff on the ground and drive away, if you want them to dump the
stuff in the hole, then a pony truck might not want to do it, because
after dumping the pony it will be a *** to back it around the hole
to dump the main truck... it's doable, but some guys might not want
the hassle, and it's better to find out *before* he dumps it all out
on your lawn and ***s off.
