Hydro Excavation services

Our experts here at Alawa Plumbing Pty Ltd also provide services to the water and sewer infrastructure in Darwin and Palmerston, such as Closed Circuit Television Works (CCTV) for pipelines, storm water, and water supply. We also carry out vacuum extraction and hydro cleaning of pipelines, septic tanks, pump stations, and ponds. We can provide hydro excavations around existing services in situations where access and manoeuvrability may be limited.
This type of excavation is also called “vacuum excavation”, “potholing”, “hydro-digging”, “hydro-trenching” or “soft digging”. Regardless of the name the basic process is always the same though, pressurised water or air and a vacuum source to remove the material.

This type of excavation is also called “vacuum excavation”, “potholing”, “hydro-digging”, “hydro-trenching” or “soft digging”. Regardless of the name the basic process is always the same though, pressurised water or air and a vacuum source to remove the material.

 

Hydro-Excavation is a non-mechanical and non-destructive process which combines pressurised water and a high flow of moving air to simultaneously excavate and evacuate native soils at a controlled rate. The soil and water slurry are conveyed via a tube to a truck-mounted debris tank. This process allows for quick, clean and precise evacuations which require less backfill, less labour force, less restoration, and less environmental impact than conventional digging methods. A controlled flow water stream allows for surgeon-like accuracy. While removing only material necessary for repair or inspection, minimal material needs to be removed when compared with the large, less-than-accurate excavator or back hoe bucket.

 

A Hydro-Excavator or ‘hydrovac’, or ‘suck truck’ for short, is a completely self-contained unit which is comprised of several pieces of equipment. The complete package is absolutely necessary to provide the most efficient service to the customer.

Possible applications of the hydrovac include:

  • Replacement of pipes and fittings
  • Renovation and new installation of gas-, water-, heating pipes, cables and disposal lines
  • Exploratory excavations
  • Exploratory excavations
  • Use of ground displacement rockets
  • Clearing away environmental damage
  • Replacement of contaminated soil around the roots of trees
  • Removal of material in demolition projects
  • Removal of gravel from flat roofs
  • Cleaning blocked street gutters & gullies
  • Operations involving the use of horizontal boring units
  • Leaf removal
  • Application for special operations

 

Hydrovacs eliminate the need for costly and time-consuming manual labour. Buried pipe systems do not suffer damage. Output is up to sixteen times of that achieved by conventional excavation.
