In 2018, the Liner Integrity Survey and Assessment Division of TRI performed a record number of electrical leak location (ELL) surveys encompassing over 10 million square feet. TRI’s Australasia, China, and Brazil offices also continued to offer this service. TRI’s new Africa office is now also performing this service in South Africa, where it is now a regulatory requirement.
TRI’s in-house manufacturing process of the LISA 3000 Series ELL equipment is now complete. The multifunctional kit that TRI produces can perform dipole surveys using GPS-based data acquisition as well as the water puddle and water lance methods. In 2018, a new ASTM standard practice for ELL methods was authored, which requires mapping technology perfected by the 3000 series equipment. TRI expects this new important standard to be published in 2019.
