Vacuum Tanker Services
A Hydrovac vacuum truck's pump is designed to pneumatically create a vacuum that sucks liquids, sludges, slurries, or the like from a location (often underground) into the tank of the truck.
A common material to be transport is septage (or more broadly: fecal sludge) which is human excreta mixed with water, e.g. from septic tanks and pit latrines). They also transport sewage sludge, industrial liquids like oil or produced water, refined products, or slurries from animal waste from livestock facilities with pens. Even potable water if needed.
Vacuum trucks can be equipped with a high pressure pump if they are used to clean out sewers from sand.
It is common for fluids to be thick or dense. It is very advantageous for a Hydrovac to have heated high-pressure water capability to dilute the materials into a slurry or less dense. This makes it easier for the high-powered vacuum created by a Hydrovac to vacuum on the slurry.
Hydrovacs make great vacuum trucks as they can solely be utilized for moving fluids without having to excavate it. For example, if you have a large swimming pool, it would take the hydrovac only minutes to suck that water into the debris tank. Then the water can be hauled off location as per the customer’s request & unloaded where wanted. This is just one example. Also, if you have a water sensitive environment that you do not want to use water & have loose soil which does not require water stimulation you can suck dry soil onto truck & haul away. One example of this was dry sod for a customer that did not want erosion from water use. We sucked on several loads of dry sod & hauled to clean fill location. A typical vac truck does not have a strong enough vacuum to achieve this.
