The company has engaged specialist consultants to survey and collect data via aerial photogrammetry and in-channel bathymetric survey across all civil and earthen assets.
Murray Irrigation head of water delivery Jarryd Pearce said aerial photogrammetry and in-channel bathymetric surveys were innovative technologies that will allow the company to efficiently collect data on and analyse all its assets.
“Murray Irrigation has a huge footprint, with 2755km of channel system and around 3500 bridges and culverts,” Mr Pearce said.
“For the company to send out individual staff to each site to gather this data, it could take years, would incur high costs and lack consistency across how the assets have been captured and inspected.
“By utilising this survey technology, the company will have a consistent set of data captured over a one to two month period that can be stored and analysed to determine the condition of all our assets, which will enable our asset management system to be aligned to best practice.”
Once the survey has been completed, all data will be compiled and digitally assessed over a 12 to 18 month period to provide a comprehensive condition assessment of all civil and earthen assets, including a defects list and silt volumes in channels.
The data will also inform the improvement of the company’s long-term condition monitoring strategy, which could involve imaging technologies such as drone and satellite to monitor weed levels and location.
“This is the first time Murray Irrigation has assessed and benchmarked the entire earthen asset base, which is the largest and potentially highest risk asset due to its potential impact on long-term asset liability,” Murray Irrigation CEO Ron McCalman said.
Bathymetric survey uses sonar to measure the bottom of a body of water, in this case, the company’s earthen assets such as channels.
Photogrammetry uses low flying aircraft to capture high-resolution imagery of terrain. This method will primarily capture the company’s civil and earthen assets above the water line such as channels and structures.
“These aircraft will be flying low over the area periodically during February and March,” Mr McCalman said.
“The focus of the survey is on Murray Irrigation assets across the whole footprint, and is not intended to capture any private property. However, if it does so, that survey data will be handled in line with the company’s privacy policy, which can be found on the Murray Irrigation website.”
