Dam Safety Monitoring, NSW, Australia

Australia’s longest road tunnel at 11kms long, this project is located near the Blue Mountains Region of NSW. When completed, the $2.5Billion project will form the main road corridor between Central Western NSW and the Sydney Region. Over 100 boreholes were drilled with some fitted with VWPs and others with monitoring wells, EWS Well-Caps and VWT devices were installed and are providing critical remote data over Iridium satellite connectivity for the geotechnical investigation.

Four large TSF's in Australia's Northern Territory and Northern Queensland area retrofitted 1000's of vibrating wire piezometer sensors with EWS' Iridium VWT devices to replace the unreliable radio datalogger networks previously installed. The upgrade provided the TSF's with the easy to install devices which transmit individually over the Iridium Satellite network, removing the risk of single point failure. The increased reliability and visibility of critical geotechnical data relating to the TSF assists the mine in meeting its GISTM obligations.
