Highly Reliable and Efficient Services for Gross Pollutant Traps and Vacuum Excavation for Industry

Gross pollutant traps (GPT) trap solid waste such as litter and coarse sediments via physical processes. This makes it easier to remove finer sediments from wastewater in the future. These are put in place to catch stormwater pollution before it enters a waterway. At the downstream end of drains or constructed waterways that flow to rivers and urban lakes, gross pollution traps are built.

Gross pollutant trap typically consists of a sediment trap with a weir and trash rack at the downstream end. Flow enters through a concrete-lined basin and detained by the weir, improving sedimentation in the process. To manage flow and capture sediments, the system employs a network of underground chambers, screens, and weirs. The waste rack gathers debris from weir overflows. Gross pollutant traps act as a filter, trapping litter while allowing water to pass through. It can also be used to pre-treat stormwater harvesting systems. These provide a cost-effective way to reduce the contaminant loading of a site and reduce the need for system maintenance.

GPTs are primarily used to remove large and non-biodegradable pollutants. Gross pollutant traps use physical screening, rapid sedimentation and separation processes to trap and filter waste. It traps litter and sediments above 5 mm in size so that these can be removed from the waste system.

Besides trapping litter and coarse sediments, gross pollutant traps also provide reduction in a variety of other pollutants, such as:

• Removal of particulate nutrients
• Removal of oil and grease
• Removal of trace metals
• Reduction in bacteria
• Reduction in dissolved oxygen demanding substances

Gross pollutant traps serving small catchments can be installed underground. To ensure proper operation, the gross pollutant trap must be cleaned on a regular basis. Aussie Hydro-Vac Services has a qualified crew that understands how to service gross pollutant traps using the proper equipment and materials. The organisation offers both one-time and planned servicing of gross pollutant traps for cleaning and maintaining its chambers, gross collector, bypass channel, silt chamber, garbage screen, and sections of GPT.

Vacuum excavation to keep your underground utilities safe

Aussie Hydro-Vac Services vacuum excavation uses high-pressure water or air to break up soil and debris. The slurry is extracted with the assistance of a vacuum, which is generated either by a fan system or by a positive displacement blower. The company's vacuum excavation unit may use a twin or triple air fan design to produce a bigger volume of air. The material is pulled into the holding tank after passing through a micromesh filter system, which traps dust particles.

Non-destructive and safe digging method

Vacuum excavation is a non-destructive way of digging that avoids damaging neighbouring structures and underground utilities. Vacuum excavation eliminates the need for manual or abrasive excavation methods. The soft digging approach is deemed safe since it protects employees from trench cave-ins. When working in frozen ground, hydro excavation is useful since hot water can be used to defrost and break the soil. Vacuum excavation is a low-impact, non-destructive digging method that is gaining favour in Australia due to its high efficiency and cost-effective operations. Aussie Hydro-Vac Services can supply you with the best vacuum excavation solution for your project's needs.

Key applications of vacuum excavation

Can be used to perform deep excavation for large depths, like cleaning storage tanks. Deep excavation provided by vacuum excavation is best suited to perform renovation or restoration of a building or structural foundation.

Underground utilities, cables, and pipes can be exposed without causing any damage to them. This way, vacuum excavation ensures that these utilities are not damaged, and your facilities remain functional while the process is underway.

Vacuum excavation is also best suited for the soil improvement techniques requiring the removal of contaminated soil and gravel, or solid spills. Vacuum excavation is also used to improve the soil around trees and eliminate roots that create a mess around the buried utilities, like pipes and cables.

In addition to gross pollutant traps and vacuum excavation, Aussie Hydro-Vac Services offers industrial services such as drain and culvert cleaning, liquid and solid waste disposal, road sweeping, industrial maritime services, and more. The company's technical services include cable and pipe location, geotech& pavement research, subsurface engineering & maintenance, drone photography services, and more. The company owns cutting-edge trucks and equipment, including a Kroll drain cleaning unit, an all-terrain medium vacuum excavation unit, a narrow access vacuum excavation unit, CCTV and geotech vans, and more. Throughout Queensland and New South Wales, the company offers gross pollutant traps, vacuum excavation, and other waste management services.
