Gross pollutant traps</a> (GPT) trap solid waste such as litter and coarse sediments using physical processes. These are commonly used as primary treatment to remove large, non-biodegradable pollutants, typically larger than 5 mm in size, from the water system. Aussie Hydro-Vac Services installs gross pollutant traps to catch stormwater pollution before it enters the waterway. It acts as a filter, retaining litter while allowing water to pass through. The use of gross pollutant traps as a pre-treatment for stormwater harvesting systems is also possible. GPT, on the other hand, must be cleaned on a regular basis to ensure that water can flow through while the collected trash does not leach pollution into the water.

2. Vacuum digging, also known as Hydro Excavation or non-destructive digging, is
the process of removing mud, dirt, and slurry from a site without damaging
subsurface utilities such as electrical and fibre cables, gas and water pipes, fixtures,
and sewer pipelines. A high-pressure water jet is used in vacuum digging to cut and
break soil. The slurry is then removed using an air vacuum by a vacuum digging
services provider.
A positive displacement blower or a fan system is used to create a vacuum source
for vacuum digging. When compared to the positive displacement blower, the fan
system is easier to use and less expensive. The fan system allows for faster
excavations and is lighter, but it is ineffective at greater depths. To create effective
airflow for vacuum digging, vacuum excavators use twin or triple air vehicle fans.
Positive displacement blowers are preferred for vacuum digging at greater depths.

3. Aussie Hydro-Vac Services (AHS) uses advanced vacuum digging techniques that
significantly reduce the risk of striking, leaking, damaging, or breaking utilities,
which is common with traditional manual digging methods that utilise shovels and
excavators. Aussie Hydro-Vac Services ensures that the cost of your vacuum digging
is greatly reduced for you, and that downtime for your facility is minimised or
eliminated entirely as your underground utilities remain operational.
