TDG delivered a comprehensive and organised solution to fulfill the client’s specified works scope, involving coordination with various contractors such as locators, traffic management, and surveyors, while navigating through multiple jurisdictions and permits including those from local government, Department of Transport, and resident notifications.

The client engaged TDG to carry out smoke testing as a proactive measure to identify and address leaks and defects in sewer systems. The local pump station for council has recorded more water going through then what is scheduled capacity. Through the implementation of smoke testing, TDG successfully pinpointed areas of concern within their sewer infrastructure, leading to targeted repairs, improved system integrity, and enhanced environmental protection.

The client engaged TDG to conduct an investigation into a pipeline connected to a drainage tank for a Community Centre, which experienced surcharge and flooding during heavy rainfall. Through CCTV investigation, we identified the pipeline obstruction caused by large tap roots and masses. Subsequently, TDG was tasked with restoring the pipeline to its full structural integrity and serviceability.

The project in Wellington involved TDG Environmental using Multi-Sensor Inspections (MSI) to profile interceptor corrosion, resulting in the discovery of rapid degradation, demonstrated through a comparison report spanning 2013 to 2020, highlighting the need for ongoing inspections and leading to client satisfaction and pipeline relining.

TDG was tasked by the client to conduct comprehensive data collection within the project’s catchment area to evaluate network conditions and renewal needs. This involved employing various techniques, including CCTV inspections, laser profiling, and GPS surveying.

The successful removal of a submerged car from creek in Sydney NSW, conducted by experienced contractors via crane while ensuring minimal environmental impact and implementing traffic control for public safety, resulted in a safely accessible site following completion of fencing repairs and car removal.

TDG provided liquid waste removal services for the 2023 Airshow, managing the largest attendance in the event’s history; approx 20,000 per day during the trade days and 80,000 people per day during the general public days. With 8 vehicles strategically stationed on site, we removed over 710,000 litres of liquid waste throughout the event.

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.

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.

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.
