Scope

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

Challenges

• Heavy silting of pipes, some with more than 70% silt/sludge, large tree roots and other obstructions. Efficiently cleaned with TDG’s drain cleaning equipment.
• Numerous pits in the network were buried under asphalt. TDG had to find innovative ways to CCTV and clean multiple lines to maintain the project deadlines.
• Dense residential area required close customer engagement and considerations for the community   
• Many old assets were not recorded accurately. The time and effort put in revealed an additional 40% more pits and pipes accurately mapped and captured on the GIS.

The outcome

The client has a better understanding of their stormwater assets location and condition ratings. TDG Environmental were able to offer options and estimates for rehabilitation of the pipe networks.
