This project’s objective was to amalgamate drainage information into a single system to improve the capability of Main Roads WA (MRWA) to react to emergencies and prevent catastrophic failures of assets. The data has been captured in a format tailored to MRWA needs based on a drainage specification in use by multiple Local Governments across Australia.
Talis has been involved with MRWA from the inception of this project, undertaking a pilot study in 2014 to ensure the required objectives could be achieved to a high level of accuracy using cost-effective methods. Since this initial study, Talis has mapped underground, subsoil and overground drainage for over 500km of freeways, highways and other state roads in multiple stages.
Coordinate and attribute information has been collected using a well-defined series of processes in order to achieve a consistent dataset. Stringent quality checks and validation techniques have maintained a high level of accuracy to ensure the database is relevant and functional. Talis have developed a Data Management Plan to accompany the system and guide its users.
As Talis’ involvement in this project has continued, our experts have developed and improved processes to extract, translate and load data more efficiently. Independent field verifications have been undertaken by MRWA to demonstrate the relevance and accuracy of the existing source data and translation outputs.
The benefits of the resulting Drainage Asset Management System include:
- Transfer of drainage data to existing systems to assist in the management of the network including preventative maintenance;
- Determination of asset location and pipe configuration within seconds;
- Availability of a drainage asset register to accurately value assets and retrieve asset dimensions and materials;
- Integration with other government organisation systems;
- Simplicity of ongoing system maintenance including addition of new assets or project stages; and
- Ability to perform trace functions on the localised drainage networks from sink to source or vice versa, in order to ascertain flow direction and possible pollutant entry or exit points.
