Water Leakage Control and Detection :
BUDA helps to monitor, control, locate, localize and pin-point any suspected leaks (Picture 1 & 2) from any pressurized water supply system.

Hydrogen Testing for Gas Leaks
To detect possible leakage in pipes, ducts or cables, BUDA uses hydrogen gas in control of nitrogen to achieve such means.

They have the most advanced technology and equipment including Data Loggers, (Picture 3), Leak Noise Correlator (Picture 4), Mechanical and Electronic Listening Devices and Gas Leak Detectors to facilitate this type of investigation. BUDA's experienced leakage detection experts will reduce survey times while obtaining the most accurate results, thus preventing any further loss of water and ultimately save time and money for our clients.
