How It Works

The technology uses spectral aerial imaging – taken from satellite-mounted sensors – to spot leakage in underground
distribution and transmission pipes. The raw imagery is then overlaid on a client’s GIS water network and is processed by a unique algorithms. The algorithm detects drinking water by looking for a particular spectral “signature” typical to drinking water. Water Vision Technology processes the data to deliver a pinpointed leakage graphic report overlaid onto a map with streets, pipes and size information.

The result? Leaks are found without the time and manpower of field based acoustic surveys.

Technical Specs:

  • The innovative satellite scanning technology detects leaks efficiently, accurately and faster than existing solutions.
  • Remote sensing of subterranean water leakage is based on a primary algorithm that detects underground leaks by analyzing micro-spectral satellite imagery. Microwave satellite images as received as input and then applies mathematical manipulation and analysis to provide a vector of coordinates.
  • Water Vision Technology processes the collected scan data and provides the utility with the leak locations and estimated leak size. From discreet, professional technical support to turn-key programs that perform all leak correlation for utilities, Water Vision Technology works closely with utilities with solutions to convert found water leaks into revenue.
  • The technology is based on microwave reflectometry, or microwave electromagnetic signals. Microwaves are particularly useful for water detection, as water exhibits a high value of relative dielectric permittivity, therefore enabling the discovery and measurement of water in soil.
  • The technology has selected a specific microwave wavelength not only for its ability to penetrate the ground, but also due to its high sensitivity to treated water characteristics.
  • Water Vision Technology surveys an entire network periodically, providing monthly or quarterly results as requested.
  • Each scan typically requires only 2-4 days of field correlation to isolate the leak, raising the effectiveness of acoustic teams so that they can focus on the last few meters of a leak detection.
