Hydro Excavation


Can some one please educate me on the difference between a hydro vac truck and a sewer/rodder truck. Is it just the rodder reel on the front or are there other differences. Can you use a sewer vac truck for hydro excavation? And if so what kind of nozzle are you using on the jet hose? Any help is appreciated.

Re: Hydro Excavation


The largest difference is what the truck is set up to do. Some of the trucks and do either. A Badger truck will only suck. It does have water for potholing but Iíve never seen a Badger Truck with a sewer jet reel. Some of the sewer jetters have a vac and older models are just stand along jetters.

Re: Hydro Excavation


Well I guess what I'm confused about is what makes a truck set up specifically for hydro excavation any better then a sewer jetter truck looks like you would have the best of both worlds besides it seems like you can pick up a Vactor truck allot cheaper then any actual hydro excavation truck?

Re: Hydro Excavation


A vactor will work and can also jet. Some also depend on what type of vacuum pump is on the truck as well. Many of the vactors have a big fan. Most of the better performance trucks designed for potholing will use a positive displacement pump. Most will work either way. Some work better doing certain things. Just depends on your main use

Re: Hydro Excavation


I'm looking for something to mainly do pot holing and excavation work but having the rodder available would be handy at times

Re: Hydro Excavation


The fan on the vactor is how they get their vacuum instead of a pd pump. The fans have to have air movement in order to work. The pd pumps can be completely submerged and still work although it performs better with air movement.

As far as the rodder they can be useful if your in that line of work

Re: Hydro Excavation


Fan or Pd units both work for pot-holing. They both have pro's and con's.

Fan unit's are much more forgiving, they will take a beating and keep going, especially when the check valve fails and you run some debris through them (pd don't like that).
They also generally have a higher CFM than pd's.
But they do need constant air-flow or you lose suction.
PD's are better suited for long runs away from the truck, as they maintain more constant suction.
I have one of each, and tend to use the fan unit more, mostly because of the forgiveness to the more unobservant employee's.

For washing, anything will work as long as you have a pressure pump that will push 2000-3000 PSI @ 3-10 GPM. Obviously the more flow and pressure, the faster it will dig. And use a good quality rotory nozzle that is rated for you pump.
