The well water which is collected in a concrete basin is pumped to the water preparation equipment, where it is filtered and treated in such a way that a TDS of 150-200 ppm is obtained. If appropriate, fluoride is added to the pre- prepared water. This water is pumped to the filling line.

The bottles, made of PET preforms, are formed in a blow moulding machine. The preforms, stored in cartons, are tipped into a reception hopper. From there they are aligned and transported to a pre-heater. Then the preheated preforms are automatically put into blowing moulds where they are filled with highly compressed and filtered air. By being pressed into the moulds, the preforms are given their final shape. The finished bottles are transported by means of a special blowing conveyor system to the filling machine.

The caps for the bottles are produced with an injection moulding machine. The raw material is filled into a mixing device from where it is transported to the injection moulding machine. The mixture is melted and injected into the moulds, where the mass solidifies into its final shape. The finished caps are discharged into bins. These bins are carried to the filling machine and the caps are manually tipped into the reception hopper of the cap conveyor.
