The Efficiency Of Hydro Vacuum Excavation- How It Can Save Time And Money On Your Next Excavation Project

Jun 03, 2023

Hydro vacuum excavation, also known as hydro excavation or potholing, is a method of excavation that uses a combination of high-pressure water and an industrial vacuum to safely and efficiently expose underground assets. Nick, the owner and one of the operators of Gold Coast Vac Trucks, shares how this method is becoming increasingly popular across many non destructive digging scenarios, including the construction industry, as it offers a range of benefits over traditional excavation methods. The main benefits Nick has seen over many years and countless jobs are time and cost savings.

Hydro Excavation Efficiency

The efficiency hydro vacuum excavation brings to job sites cannot be understated. This method can be completed quickly and with minimal disruption to the surrounding area. The high-pressure water is able to break up the soil, making it easier to remove, and the industrial vacuum is able to quickly and efficiently remove the soil. This process is especially useful when working on sites with dense intersections of underground infrastructure. Nick has seen scenarios in which power lines, sewerage pipes, water pipes and fibre-optic communication infrastructure converge into one pit and cross-over within millimetres of each other - see the picture below.


In these cases traditional excavation methods are simply not practical.  Hydro vacuum excavation is far more efficient as the water jet quickly exposes all of the underground infrastructure and assets, and the vacuum quickly removes the soil and debris surrounding the area of interest.

Hydro Excavation Precision

In these complex scenarios, precision is critical. Our Gold Coast based vac truck allows for the precise creation of holes and trenches with minimal effort. Precision is also essential when potholing for underground utilities. All of these techniques allow for the safe and efficient underground service location and exposure of underground utilities, without causing damage to existing infrastructure. Nick has seen the ramifications of non-precise techniques such as backhoe excavation and manual digging first hand many times! Service disruption and potential safety hazards are the immediate effects. From there a long list of issues can arise including large repair costs, legal disputes, legal costs, construction delays and so on.

Hydro Excavation Cost-Effectiveness

The efficiency and precision gained via hydro vacuum excavation means it is often the most cost-effective option. Nick often sees people regretting their decision to manually dig, as when something unexpected occurs the labour costs blow out. The same occurs when digging equipment is hired - cost blowouts happen all the time as there are lots of surprises found after you start digging.  Hydro excavation is best suited to handle those otherwise costly underground surprises.


Remembering the reduced risk of injuries, the lower likelihood to cause damage to underground utilities, hydro vacuum excavation stands out as an extremely cost-effective option.

All-in-one Location, Excavation and Debris Removal

Excess waste and debris removal is often overlooked by people considering which excavation option to take. And that oversight can be in terms of the time taken to remove debris from a worksite, and/or the costs involved in removing debris. Waste centres that accept this type of waste are few and far between. Gold Coast Vac Trucks handles everything for you.


Gold Coast Vac Trucks handle all aspects: the location, excavation, asset exposure and debris removal. Most of our jobs involve parking the truck, extending the water jet hose and vacuum pipe, exposing the underground assets, removing the debris, retracting the hose and vac pipe, and dumping excess debris at a waste centre. By incorporating these tasks into an all-in-one service, this is the ultimate in terms of cost-effectiveness.
