Withdrawal Rate of Water using Vac Truck
Withdrawal Rate of Water using Vac Truck
(OP)
Hello All,
I am trying to find the rate at which water will be withdrawn from a waterbody with "a vac truck". I know that the hose will be screened to prevent fish capture and that the hose will be 3" in diameter or less.
I expect that there are many different types of vacuum trucks in existence, making this a difficult question to answer.
The value does not need to be highly accurate (and if there is a range of values, knowing the upper bound would be suitable).
Does anyone know of a source I can turn to for this? Perhaps a guideline which recommends a maximum withdrawal rate using a vac truck?
If it makes a difference, the withdrawal will occur in northern Alberta.
Thanks!
Dave

what is the horsepower of the pump?
assuming 10 fps you could get about 200 gpm, but that would be limited by the power, friction loss and the static head
RE: Withdrawal Rate of Water using Vac Truck
200 gpm will probably be a good starting place for my purposes. Surfing the web I also found examples of vac trucks rated for ~20-100 gpm. Knowing that a reasonable ball park is probably in the 20-200 gpm range is a big step up from where I was an hour ago! Thank you both for the quick responses!

The capacity depends on the material properties of what you are pulling as well as the suction lift.
The maximum suction is vacuum or 15 psig and the hoses go up to 8-Inch size.
Here is a company that you can contact:
