Who are we

Since Hydreka was founded in 1988, its major objective has always been customer satisfaction. Always there when you need it and ready to listen to its customers, Hydreka’s strength is based on its experience, and the work of its research and development department, which enables it to offer increasingly effective products and anticipate on customer requirements, making their often strenuous work in the field a lot easier. Hydreka has all the services and measuring systems required to deal with the water cycle, in France and abroad. In 2000, Hydreka joined  HALMA plc., an international group of technology-related companies, and is now part of its Environmental & Analysis division.

Our job

From data acquisition to data analysis, Hydreka is there to offer you solutions to meet your water network management needs.
Our mission is to be one of the global leaders and experts in standalone, communicating instrumentation solutions for the better management of water resources. The rapidly growing and urbanizing world population places huge strains on water resources and networks. Increasing climate instability has made severe weather more common, and water availability more complicated to predict. Water monitoring and management is increasingly crucial to provide and maintain access to safe drinking water, and support agriculture, energy, transportation, manufacturing, and civil infrastructure, all of which have huge implications for life and health.

Hydreka provides solutions to accurately measure the entire water cycle. We rent and sell a wide range of products across five application sectors, which can be combined and configured to report hundreds of parameters. All products are offered in combination with software packages to report and analyze the collected data. This flexibility allows us to provide uniquely tailored solutions and high-quality data, where and when you need them.
