Hydro Vacuum Excavation/ Non Destructive Digging (NDD)

What is Hydro Vacuum Excavation or NDD?

Hydro vacuum excavations is a process that involves the use of water and air pressure to safely and efficiently remove soil and debris around underground pipes, utilities, and other underground infrastructure. This method eliminates the need for heavy machinery and reduces the potential for damaging underground assets. The high-pressure water breaks up the soil and the vacuum system removes the debris, leaving a clean excavation site. Hydro vacuum excavations are widely used in industries such as telecommunications, oil and gas, and construction to minimize the risk of accidents and damage to underground infrastructure.

Non destructive digging (NDD) is governed by legislation in many countries, including Australia, where laws dictate techniques, equipment and personnel involved in such excavations. In NSW and Victoria, non destructive digging is managed by Worksafe, while Queensland has the Plant Code of Practice and Work Health and Safety Regulation. This type of excavation is often used as an alternative to traditional excavation methods, as it minimizes disruption, damage to underground infrastructure, and risk to workers. The legislation aims to ensure safe and efficient non destructive digging practices are adopted, and workers are kept safe from harm.
