For both deep and surface water entering the Kristineberg Main Building, salinity and temperature are continuously measured. It can be seen on the Water and weather data web page. Compiled measurement results from 2007-2013 and 2016-2018 are shown in diagrams below.
The deep water intake is at 32 metre depth. It is pumped up through the Main Building to a water reservoir on the third floor. The water is flowing through four serie-connected tanks, where sediment and large particles sinks. From the last tank, the water flows down through the building to the laboratories. In the thermoregulated rooms there are screen filters in the taps. In other labs, water is unfiltered.
