Over the past 4 years Rise has partnered with PWC to innovate PWC’s WSP surveys and sludge management practices and technology.

Initially Rise invested in an Australian made bathymetric USV (unmanned surface vehicle) to do the first-ever digital bathymetric surveys of PWC’s WSP’s, providing PWC with accurate sludge and WSP 3D modelling.

However, the unique conditions of the majority of NT WSP’s (no inlet works, high organic and inorganic debris) meant the off-the shelf USV struggled.

Rise then co-funded an AMCG grant to develop the world first “Steamer” paddle driven USV which has been successfully tested in PWC WSP’s.

Rise’s comprehensive WSP services using both USV and aerial drones provides:

- Digital bathymetric survey of full lagoons to assess sediment depth and volume – to inform capital works; sludge management; compliance with Discharge Licence.

- Aerial imagery to monitor lagoon emptying process and progress.

- 3D modelling of empty lagoon to accurately measure the volume of the lagoon.
