The Challenge
Southern Downs Regional Council are responsible for stormwater networks in various towns across the region, and many rural culverts. Council was seeking a contractor to collect condition and defect data on 10% of the region’s stormwater infrastructure that would help to manage Council’s stormwater assets in an efficient and effective manner, through timely intervention, while maintaining an agreed level of service.
The Solution
Proterra Group undertook condition inspections in the field to assess stormwater assets e.g. Culverts. Pipelines and Headwalls, Stormwater pipelines, access chambers, pits, endwalls and open drains lined with concrete or stone. This was accomplished by collecting condition and defect data on existing assets, deriving condition ratings and providing data and outputs in a format that enables Council to import these into its asset management systems.
Defect information for structural integrity and serviceability was provided as indicated by industry guidelines. CCTV was carried out in accordance with the latest version of the WSAA Conduit Inspection Reporting Code of Australia WSA05. Defect information for the structural integrity and serviceability was provided as per the distress modes in Practice Note 5, Stormwater Drainage – Condition Assessment & Asset Performance Guidelines.

The Benefit
Proterra Group had previously undertaken stormwater assessments for SDRC and has good working knowledge of the network and Council area. CCTV and Quickview methods were utilised to inspect stormwater assets for this project. In cases where the pipe length did not exceed 60m, the asset was able to be quickviewed which is a faster operation than CCTV. Pipe segments were identified in GIS mapping as two distinct categories (<60m and >60m) which allowed field officers to efficiently inspect stormwater assets. GIS mapping was utilised throughout the project to monitor the progress of Quickview and CCTV inspections.
The Result
Proterra provided Council with condition ratings for the sampling of Pipe segments, Stormwater Structures and Open drain segments as requested by Council. Proterra was also able to provide a GIS dashboard that displayed the stormwater network sampling progress of this project.
