The smooth operator
SARA Water goes underground in Basel to monitor the raw water and river water used to produce the region's drinking water.
Clean drinking water is the mainstay of modern, healthy societies. Extensive and sophisticated measures are therefore needed to monitor this precious commodity and detect any contamination from an early stage. Rigorous standards and legislation set strict limits in this regard.
Online monitoring offers clear advantages over the widespread practice of taking samples and having them analyzed in a laboratory: readings are logged in full and always up to date. Industrielle Werke Basel (IWB) has just implemented this service for its customers in the Swiss canton of Basel-City and surrounding municipalities: installed in the tank of the fast filtration plant, SARA Water now monitors the raw/river water around the clock for inputs of artificial radio isotopes and changes in the natural radiation.

Thanks to its in-situ nuclide detection, SARA Water reliably identifies the slightest change of less than 1 nSv/h and enables the element-specific impact potential to be clearly determined without delay. The automatic, finely configurable alarm functions of SARA and NMC ensure that any deviation gets the attention it deserves. Moreover, data is permanently logged over many years, providing a complete documentation of the readings and results.

This form of early detection online is particularly useful when reservoirs are fed by watercourses, but also for those exhibiting large fluctuations in their natural setting. With IP69K protection and a maximum diving depth of 500m, SARA Water can be deployed 24/7 for measurements both directly in the reservoir and in its feed waters.
