How Do Hydro Vacuum Excavation Services Work?

by Maria Williams Online Marketing Specialist

Many different traditional methods are used for digging and excavating, and they are still viable solutions in various scenarios. But digging a trench is sometimes difficult when there are buried conduits/pipes in the construction area. 

In such a situation, hydro vacuum excavation is considered the most effective and reliable method that allows service professionals to get the job done promptly. Therefore, this specific excavation method is becoming increasingly popular for many reasons. Read on to learn the reasons to use it, its areas of application, workflow, and more.


Hydro vacuum excavation is a superior way to excavate compared to traditional digging techniques. Its primary benefit is that it drastically reduces environmental and safety risks. The trench or hole produced by the hydro jet is small and allows for the precise location of utilities, eliminating the need for extensive site restoration. Apart from this, you can adjust the pressure of the water via the hydro jet nozzle to minimize the risk of damage to tree roots. Last but not least, hydro vacuum excavation is much gentler compared to other excavation methods, making it suitable for environmentally sensitive areas.

Application Areas

Hydro vacuum excavation suits civil, construction, industrial, and domestic requirements. Its specific application areas include (but are not limited to) the following:

•    Piling Hole Excavation

•    Debris Removal Via Suction

•    Confined Digging

•    Cleaning of Catch Basins

•    Manhole Cleaning

•    Culvert Cleaning

•    Utility Service Repairs

•    Under Structure or Object Excavation

Workflow of Hydro Excavation Services

Hydro vacuum excavation is a non-mechanical and non-destructive service that uses a vacuum system and pressurized water to excavate and dig out the soil simultaneously. The technique works by pressing water into the ground via a “hose” that liquefies the soil. Once the soil becomes a slurry mix, a powerful pumping machine is used to vacuum it easily. The wet soil mix is usually collected in an attached debris storage tank.

Hydro vacuum excavation service can dig up to 70 feet deep, and the pumping truck or holding tank can be placed at a long distance. Hydro vacuum excavation service companies use specially designed hydro-vac trucks to excavate soil naturally and optimally.

The Process

The typical hydro vacuum excavation process uses a machine that contains the following equipment:

•    A large water reservoir

•    A cyclone vacuum unit

•    An on-board water heater

•    A very large debris tank

•    A high-pressure water system

•    A diameter suction hose

The process includes the following steps:

1.    Hydro vacuum excavation professionals insert the water band in the ground, making the soil loosen and slurry with high-pressurized water.

2.    A vacuum hose and a powerful pumping machine suck the wet soil.

3.    Finally, an attached storage tank stores the unwanted, compressed debris. Professionals heat the water steam for frozen ground soil to loosen the ground.

Overall, hydro vacuum excavation services are the most precise, cost-effective, and least intrusive digging services available. They are also the safest for both people and the environment. 

Before hiring the services of a hydro vacuum excavation company, make sure they use the latest equipment and techniques so your project is completed efficiently and on time.
