Creating new infrastructure can stimulate the economy and improve the quality of life, however, the impact it can have on communities and the environment should be taken into consideration. To minimise the impact of infrastructure projections, non-destructive digging (NDD) is a great alternative to conventional digging.
NDD, also known as vacuum excavation or hydro excavation removes the soil and other ground materials using high pressure water and air. This is a low impact method which ensures that the ground material is removed without damaging other foreign objects in the ground such as pipes and gas lines. The pressure mimics the effect of mechanical digging but because the pressure is focused on the target, it doesn’t impact the surrounding area, underground assets or tree roots. After the material is loosened it is vacuumed out using a high-volume suction hose into the hydro vac storage tank.
Due to the non-invasive and low damage effect to the environment, there are many benefits to NDD. The benefits of non-destructive digging include:
NDD is a great option when excavating near underground services like sewerage pipes, gas, water and telecommunication lines as NDD is very precise, leading to less critical importance to know the exact depth, location, direction, types and routes of existing pipes, cables and other underground infrastructure. Mechanical drilling can be slow and has a high risk to surrounding areas. As NDD uses water, it has the added benefit of dust suppression in an instant, which can be helpful in residential areas.
Due to not having to use mechanical equipment for digging, the pressure applied during NDD is significantly quieter which is very important in residential and metropolitan areas with residential properties and foot traffic. The NDD excavation only has the noise of the pump which is relatively low and does not last long.
Fewer crew members are required in NDD, reducing operational costs and man-hours needed to undertake manual spot digging. NDD also ensures less mess than other conventional approaches to digging, which significantly reduces clean up time. Materials vacuumed into the truck, can go straight back into the hole once the project is complete, ensuring there is minimal remediation costs in backfilling. This also reduces the cost for material removal which traditional excavation methods will need to use, as an extra truck is not needed to take materials away. The non-invasive method also eliminates the cost for potential repairs, as it is more precise and will not damage underground infrastructures in place.
Using NDD allows the implementation of a highly precise controlled process and operation from start to finish. In many cases, NDD will not disturb, damage, or replace footpaths, roads, curbs and gutters or surface drains, creating less impact on the environment. NDD is so precise due to the fact that an operator stands over the excavation as it happens and can make adjustments as necessary.
