AUSGUST 2020 SEDIMENTATION PROFILING SONAR SURVEY OF STORMWATER OUTFALL USING ROV

Desilting stormwater pipelines presents its own set of challenges for councils and state asset owners. One difficulty is providing companies with accurate quantification and composition of sediment accretion within pipelines, culverts and tunnels. AUS-ROV has developed systems which allow for accurate 3D modelling within conduits to enable stakeholders to assess the quantity of sediment within their water infrastructure. These surveying techniques can then be repeated periodically or after contractors complete pigging or desilting in order to gauge the extent or success in removing foreign debris and sedimentation. Comparitave reporting can inform asset management of rates of accretion or assist in developing an understanding of the effects of storm, flood or tidal surge mechanisms. AUS-ROV’s specialist engineers, with decades of experience in stormwater and coastal engineering, can provide clarity on the general internal condition of conduits in what is otherwise typically a difficult asset to manage with traditional diving and confined space entry.
