A canal in Sydney required vegetation removal and desilting works to restore proper water flow and reduce the risk of flooding during heavy rainfall. The site presented significant access challenges, including no ramp access and extremely tight working conditions. TDG Environmental was engaged to provide a solution that would overcome these limitations while ensuring safe […]
A heavily overgrown canal in Western Sydney required urgent desilting and vegetation removal to restore water flow and reduce the risk of flooding. Due to the steep embankments and absence of ramp access, traditional excavation methods posed significant safety risks. TDG Environmental was engaged to deliver a safe, efficient, and non-entry solution to clear the […]
Confined Space Risk Eliminated: All works completed using equipment, removing the need for personnel entry.
Flow Restored & Flooding Prevented: Full desilting and debris removal ensured unobstructed water movement.
Efficient, Non-Invasive Execution: Completed without ramping or major civil works, reducing time and risk on site.
TDG Environmental successfully rehabilitated the sewer pipeline, achieving a fully sealed and structurally reinforced solution. The intervention prevented potential sinkholes, safeguarded the roadway, and ensured the long-term reliability of the asset.
Enhanced Structural Durability: The CIPP patching method provided a 100-year design life, ensuring long-term pipeline integrity.
Prevention of Future Sinkholes: We eliminated any chance of a sinkhole forming, which could have compromised the road surface.
Client Satisfaction: The asset owner and client were very happy with the quality and efficiency of the work performed.
A newly placed power pole was installed through an existing asset, causing a major obstruction and presenting a potential flood risk. The issue required a rapid and comprehensive intervention to prevent further damage and ensure the continued functionality of the affected infrastructure.
A severe sewer blockage obstructed 99% of a 1075mm diameter pipe located 30 metres underground, requiring urgent and complex intervention over a 2.5-week period.
Engaged to assist in flood recovery efforts for a regional council area, we set out to clean debris from 9 x 825mm pipes, including their inlets and outlets. Services provided: Kaiser Water Recycling Unit to allow for continuous cleaning operations, despite there being no onsite water An excavator and tipper to remove excess debris Traffic […]
The project’s main goal was to conduct lateral lining installations within wastewater connections, a task requiring a high degree of expertise and precision. Our team met this challenge with remarkable proficiency, delivering outstanding results that surpassed expectations.
TDG was engaged for assessment and rectification of 4.5 kilometers of Stormwater conduit and maintenance holes, utilising CCTV inspections or physical traversing methods, followed by necessary rectification works.
TDG was engaged to pressure clean and record data from pressure drains at the base of the Dam wall and spillway. The drains provide important pressure release role in operation of the dam to mitigate destabilising pressure in the structure.
This project aimed to assess silt levels within a 2.4km, 1200mm ocean outfall from the primary wastewater treatment plant to the ocean discharge using a sonar-equipped, neutrally buoyant sub from the MSI toolkit. A specially trained 5-person crew traveled from Auckland to Timaru over two days for the inspection, as the outfall, initially inspected in […]
