Smart membranes and pipe monitoring networks; waterproofing and real-time leak detection systems

Sensor UK developed electronic geomembrane leak location monitoring systems for use on hazardous waste storage sites in the 1980s. The technology has been developed and adopted by industries to provide reliable and accurate geomembrane leak detection, designed to contain or protect assets.

The technology came to the UK water industry during concern for failing assets and unreliable coating systems, crucial to potable water supply. Various levels of protection have been developed from simple loose‐laid impermeable membranes to real‐time notification systems and remote operating of the membrane interrogation software.

A DWI Regulation 31 Approved geomembrane, designed for use in contact with potable water utilising the technology, identifies and locates leaks. The system has been installed above service reservoirs for various water authorities in the UK and Canada but is also suited to lining impounding reservoirs, tanks and lakes as well as chemical‐free water treatment facilities.
