During October - November, Geotest completed leak detection and the repair of a 60 mega litre potable water storage pond. The project involved decommissioning of the original deteriorated liner and a repair completed to what was the floating cover in order for it to be used as the new lining.
In order to source the leaks, we used a variety of techniques starting with the inflation of the lining. Whilst underneath, the technicians were able to see daylight through the obvious holes which were documented for repair later. We used this opportunity to install our future leak detection system. The cover was carefully deflatedto ensure it relocated correctly preventing further damage to the lining upon filling the pond with water again.
We then used a combination of vacuum testing and e-testing techniques to find, test and repair nearly 200 holes – some barely visible to the naked eye but with the potential to cause serious water loss once the pond was full. It just goes to show the amazing capabilities of our e-testing systems!
