Hi-tech water efficiency system
Takadu is a world-leading Israeli
technology designed to monitor the
distribution and provision of drinking
water. The system provides real-time
information on leaks, breaks and other
inefficiencies. It analyses flow and
pressure inside pipes and factors in
external data, such as climate and
seasonal water use. The information is
automatically collected centrally for
detailed analysis.
2011 was the first full year in which we
used the system and we were able to
detect leaks better, improve equipment
availability, reduce minimum night time
flow, and decrease the time it took us to
respond to problems in our water pipes.
Aguas de Antofagasta expects the use of
Takadu will help to reduce water losses
and increase overall efficiency.
