As water gushes through the labyrinthine infrastructure of the London water supply system, an ageing pipe creaks, whines noisily, and finally bursts.
Within seconds, an alert starts flashing on a remote computer in the tiny office of Takadu - an Israeli start-up in Tel Aviv.
Once picked up, the information is transmitted to Thames Water - the utility company responsible for bringing water to Londoners.
CEO Amir Peg on how Takadu works with water companies: "Almost instantly, we're able to detect, alert, locate, and basically inform the utility that there's something wrong," says Amir Peleg, Takadu's co-founder and chief executive, pointing to a computer screen.
The firm's specialization is smart water systems.
Thanks to Takadu, as well as to other measures, Thames Water managed to achieve five annual leakage reduction targets in a row.
Last winter, it received the prestigious 2011 Tech Pioneer award at the World Economic Forum in Davos.
