Hunter Water signs 3-year subscription to monitor Grahamstown Dam

Posted: Sunday 3rd May 2020

Rezatec, in association with its partner Detection Services, will provide ground-breaking geospatial analytics to monitor structural and environmental change at Hunter Water’s Grahamstown Dam, Australia until 2023.

Following a successful initial deployment, which proved correlation of Rezatec’s analytical insights with previous events and subsequent works, Hunter Water has now moved forward with a 3-year subscription to monitor Grahamstown Dam.

Hunter Water’s Dams Safety Engineer, Daniel Turnbull, commented, “From our first encounter with Rezatec, they have been great to work with. We are very confident in the capability of Rezatec’s technology and this subscription will help enhance our monitoring of Grahamstown Dam.”

Using sophisticated analysis of satellite derived imagery and geospatial data, Rezatec’s technology allows for a risk-based approach to monitor dams and reservoirs, with sub-centimetre precision. Due to the wealth of archive satellite data available, this technology is the only way for dam owners and engineers to look retrospectively at changes and trends over time. This enables a historic duty of care, with accurate insights to identify patterns of abnormal activity. Geospatial technology is critical in addressing asset repairs, maximising operational and infrastructure issues, while optimizing capital improvement and sustainability programs.

“It’s great to have Hunter Water on board as a client and continue to demonstrate our excellence in providing satellite solutions for dam owners and operators,” stated Philip Briscoe, Chief Operating Officer at Rezatec. “Our mission is to help our clients make data-informed asset management decisions to dynamically manage the integrity and safety of their assets”.

Hunter Water has tried and tested other technologies however they have not been able to provide the same level of frequency and insight at such a competitive price, nor gain the retrospective insights via any other method.

Detection Services General Manager, Chris Evans, stated, “As a long-term partner of Rezatec’s, the Dam Monitoring product is a game-changer for dam owners and operators, with the ability to remotely monitor infrastructure accurately and frequently, without sending teams into remote locations”.
