Water and Leak Detection

Water Leak Detection

As a pre-construction services provider, specialising in data collection in support of understanding and monitoring assets, infrastructure and the environment, Central Alliance is excited to partner with Utilis to bring proven satellite scanning technology to accurately find water leaks and provide saturated ground analysis.


This revolutionary new way of detecting water leaks by analysing spectral images from satellites (applying the same technology used to look for water on other planets), means Central Alliance can assist organisations to understand the interaction between utilities and critical infrastructure, whilst separately also identifying saturated ground that may highlight drainage, or geotechnical problems.


Leak Detection


The technology uses spectral spaceborne imaging – taken from satellite-mounted sensors – to spot leakage in underground distribution and transmission pipes. The raw imagery is then overlaid onto a GIS map and is processed by using unique algorithms. The algorithm detects water by looking for a particular spectral “signature” typical to treated water. The data is then processed to deliver a pinpointed leakage graphic report overlaid onto a map with streets and pipes if required.




Fully remote – monitoring of utility leaks and ground saturation.

Coverage – wide area coverage in one satellite image.

Efficiency – leaks are found and saturated ground analysed without the time and manpower associated with the traditional methods of field based surveys providing significant health and safety and resource benefits.

Accuracy – the leaks are displayed via user friendly GIS reports that can pinpoint leaks with great accuracy including street/pipe locations.

Complete data – this data can be provided stand alone or as part of a more complete and integrated asset management approach by Central Alliance that can combine data from various sources (including geology, hydrogeology, hydrology, drainage, utility mapping, examination reports) to provide a risk map for critical infrastructure.

Integration – from various disciplines within Central Alliance including leak verification, drainage surveys, topographical and utility surveys, monitoring and investigation, to offer a complete picture and critical insights to our clients that will serve to inform the design and remediation/construction phases.
