Utilities across the world are laying new plastic pipes, often to replace older worn out assets. However they have a problem. Once the new asset is covered up and reinstatement complete, it is notoriously difficult to find it again, precisely because it is made of plastic. OXEMS has developed the OXEMS Solution based on technology originally undertaken at the University of Oxford, to address this need. Early trials have proved to be very successful and we are now beginning full rollout with UK utilities.
