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.

Dam Safety Monitoring, NSW, Australia
EWS supplied Iridium satellite devices to various dams in NSW to monitor both geotechnical and hydrometric parameters. EWS VWT devices were installed to read and transmit data from vibrating wire piezometers around the dam catchment and EMT devices were installed to monitor water levels both upstream and downstream. The remote locations of the dams had previously prevented the operators from implementing effective monitoring systems, with EWS devices Iridium satellite connectivity this problem was easily solved.

Flood Warning Systems, Pilbara, Western Australia
Rivers and weather events in the Pilbara region of Western Australia (WA) are extreme. Battling with streamflow networks that can take out entire roads & rail coupled with daily rainfall events which can range from 20mm-+100mm in the wet season, reliable early warning systems are critical for mine site operation and safety. Numerous water level monitoring sites were installed on reactive tributaries utilising the EWS Iridium Satellite connected devices. Additional Tipping Bucket Rain Gauges were installed in surrounding areas to provide more accurate and localised meteorological information to customers.
