Traffic Management and NDD Works in VIC

The project involved meticulous organisation and execution of traffic management plans, including MOAs and TGS, as well as hydro excavation to expose services and utilities for service proving. Close collaboration with surveyors facilitated accurate service proving, while careful attention was paid to reinstating surfaces to their original condition.

Project Highlights

  • Meticulous Planning: Thorough collaboration with clients and local suppliers ensured precise project execution, with works strategically scheduled for minimal disruption to the public.
  • Efficient Traffic Management: Overcoming challenges of a busy intersection, essential lane closures were managed adeptly, minimizing disruption to nearby schools and shopping complexes.
  • Timely Completion: With skilled teams and effective coordination, the project was completed well within operational timeframes, exceeding expectations and restoring normal traffic flow ahead of schedule.

Cleaning of NSW Sewer Treatment Plant

Client engaged TDG to assist with grease removal using a Class B pump for water blasting. After years of grease buildup in the sediment tank, it was deemed unsafe for the contractor to perform any hot works. TDG entered the confined space and removed all hot work hazards using high-pressure water blasting and emulsified grease down to run back through the treatment plant.

Project Highlights

  • Safe Grease Removal: TDG safely removed years of grease buildup from the sediment tank using a Class B pump for water blasting, avoiding the need for hot works.
  • Rigorous Safety Measures: TDG meticulously planned and executed the project, ensuring strict adherence to FIFM and LOTO procedures, thorough equipment testing, and provision of appropriate PPE.
  • Effective Communication: TDG maintained constant communication with the client and contractors, ensuring a smooth and safe workflow, demonstrating professionalism, and delivering successful outcomes.

Sediment Removal at Airport in NSW

Client engaged TDG to assist with a major sediment removal and rectification works project for multiple On-Site Detention Basins within an Airport in NSW. These OSDs had suffered years of neglect and were contributing to localised flooding in major rain events.

Project Highlights

  • Efficient Sediment Removal: TDG efficiently managed over 300t of PFAS-traced sediment from multiple On-Site Detention Basins at the airport, addressing years of neglect and flooding issues.
  • Cost Savings: TDG negotiated competitive disposal pricing with licensed facilities, resulting in significant savings for the client.
  • Overcame Access Challenges: TDG provided an end-to-end solution, completing the project on time, within budget, and with zero environmental harm, exceeding client expectations.

Cleaning of a Culvert Chamber in NSW

Faced with an extremely challenging culvert, this historic brick arch required precision and caution due to its fragile nature, susceptible to damage if mishandled. TDG Environmental was tasked with cleaning out the culvert chamber, measuring nearly 30m in length and 2m in width.

Project Highlights

  • TDG’s team successfully removed the debris, with over 95% being recycled, aligning with sustainability goals and contributing to a circular economy.
  • Despite the challenging conditions, TDG exceeded expectations by completing the project one day ahead of schedule.

Wastewater Inlet Works Cleaning in NSW

TDG Environmental was reached out by a local council to clean and clear the blockages at the inlet. The client was also aware that we were unable to clear the blockages without Ultra High-Pressure Water Blasting (UHPWB).

Project Highlights

  • Confined Space Entry: removing rags and debris around the blocked pipes
  • Ultra High-Pressure Water Blasting (UHPWB): leveraging cutting-edge technology to effectively clean inlet pipes and sump.
  • Eco-Friendly Solution: sucking debris and sludge out of the inlet pipes and sump with the TDG Eco Recycler

Stormwater Survey, Inspection and Condition Assessment

Stormwater Survey, Inspection and Condition Assessment of the entire North Adelaide Storm Water network

Project Highlights

  • Mapped approx 48km of Stormwater Network & over 3,800 storm water pits.
  • Provided real time updates of project tracking and digital files with TDG’s cloud based Utility Track system.
  • Fully renewed the city’s data on their critical infrastructure, and increased visibility of these assets, the outcome of nearly 6000 man hours

Lagoon Dredging in VIC

TDG’s unmanned (remote operated) dredge is unmatched when it comes to delivering efficient desludging of wastewater lagoons. The minimal footprint requirements of the equipment profile make it an ideal solution for sites that have challenging site constraints.

Project Highlights

  • Use of local providers for earthmoving works.
  • Able to complete the work on time and on budget.
  • Successfully completed the work in a challenging environmentally sensitive site to the client’s satisfaction.

Sewer Bypass in Queensland

Successful Partnership with TDG and client in delivery of Sewer Bypass in Queensland

Project Highlights

  • Equipment & Personnel were mobolised to site within 2 hours, staying on scene for 10 days
  • TDG Environmental ’s ability to ramp up immediately and execute work safely and efficiently over an extended period of time
  • Using our Superior Kaiser Technology, combined with our 22,000l Semi Tankers we were able to tanker away the inflows with minimal equipment, managing the risk profile, whilst being cost efficient for the customer.

Pump Station Wet Well Cleaning

Cleaning of one of the largest pump stations in Brisbane, handling all waste from the S1 trunk main.

Project Highlights

  • Works completed in one shift
  • TDG water recycler performed flawlessly vacuuming debris from over 30m from unit with a 20m vertical pull
  • Specialised noise cancelling headphones with Bluetooth / UHF communication allowed worker to remain protected whilst maintaining continual communication with crews.

West End 375mm Trunk Main Robotic Concrete Removal

TDG was contacted about using our high-pressure robotic cutter to remove concrete slurry that had entered a 375mm trunk sewer main during construction. Another contractor had started the process of removing the concrete deposit but their robotic milling unit was proving to be ineffective and as a result an alternative methodology was needed.

Project Highlights

  • Achieving up to 1m of concrete removal daily
  • Success development of methodology to effectively remove the concrete from the sewer main.
  • Liaising directly with client to provide daily progress updates
