WHAT IS HYDROVAC EXCAVATION?
Hydrovac excavation is the process by which high pressure water is used to break up dirt and material. This material is then vacuumed up into a truck via hose and brought offsite to a proper disposal facility. This process can also be known as hydro excavation, daylighting, potholing, or vacuum excavation.
Hydro Vac Applications:
Hydro vacs are highly versatile, and can be utilized for a wide assortment of applications.
Daylighting or Potholing
This method of excavation is used for exposing utility lines and underground pipes. Using pressurized water and vacuum suction, all types of soil can be removed from these lines without causing damage to the lines themselves. Before this method, pipeline and utility crossings had to be exposed by hand digging or with backhoes, but this posed a danger to workers if they inadvertently hit a utility line. There was also a much higher risk that lines or pipes would be damaged in the process.
This is the process of digging very narrow trenches or slots to place utility lines, pipes, or cables. Because hydro excavation allows for very accurate and narrow trenches, the job can be completed much faster than manual excavation, and a minimal amount of backfill is needed.
Anode and Shoring Installation
In order to protect the life of gas lines and underground pipes, anode pads must be installed around them to protect them from corrosion. This can be done safely and efficiently through hydro excavation methods.
Pole Hole excavation
The installation of holes for posts, poles, signs etc. can be accurately and efficiently completed through hydro excavation. Holes for these items must be of various depths and diameters. Hydro excavation uses pressurized water to create the holes and then air vacuum to remove dirt and debris.
Digging in cold weather poses many more challenges than at other times of the year. Traditionally cold weather digging has involved a lot of pollution because the ground first had to be thawed utilizing coal, wood, and/or chemicals before backhoe digging could commence. Hydro excavation, however, causes no pollution because it uses only air and water. Hydro excavation can be safely used in cold weather to remove debris and contaminated soil, etc.
Curb box replacements
A curb box is a water control valve. When these become rusted, corroded, or damaged, it can lead to flooding. For repairs to be made, excavation is usually required. Due to the urgent and delicate nature of these repairs, hydro exaction is the preferred method.
When culverts and manholes become overloaded, flooding of storm and wastewater can occur, causing significant damage and health hazards. Hydro excavation is ideal for quick and effective manhole cleaning and sewer services.
Tree Root Protection
Hydro excavation is a safer alternative to conventional digging for the protection of tree roots. Since conventional digging relies on the use of backhoes and other machinery, tree roots are often damaged in the process, which can lead to soil erosions. Since hydro excavation uses only water and air, tree roots remain undamaged.
Service pits are becoming increasingly common in several industries. Hydro excavation offers an environmentally friendly, fast, and cost-effective way to dig these pits.
For industries that utilize underground tanks, hydro excavation provides a highly accurate means of exposing tanks with minimal backfill required.

Comparison of Hydro Excavation to Conventional Digging
Using this method is a safer, more efficient, and non-destructive method of excavation than traditional manual or machine excavation.
Hydro excavation uses only water and air, making it an environmentally friendly alternative to traditional digging. The pressurized water is extremely fast and accurate and removes only the minimum amount of soil required, meaning that much less backfill is required.
Conventional digging is done manually with shovels, which is extremely slow and with backhoes and other machinery, which can be clumsy. This method removes more soil than is necessary and poses a much greater risk that there will be damage to pipes and utility lines.
Put simply, when compared to conventional digging, hydro excavation is:
- Less expensive
- Less destructive to utilities and the environment
Why are hydrovac trucks used for excavation?
Super Sucker trucks are designed to provide the ultimate efficiency for excavations of all sizes and specifications. Our hydrovac trucks are operated by highly trained, two-person crews.
Our fleet consists of both large capacity hydro excavation trucks for large jobs as well as smaller, more maneuverable trucks that can work more easily in tight spaces.
Truck-mounted water heaters mean that Super Sucker trucks can be used year-round and remote hoses allow hydro excavation to be performed from as far away as 300 feet from the truck.
