The project - "Installation of the long water tube tiltmeter in Książ Geophysical Observatory" was accepted to realisation by the Committee of Scientific Research of Poland (KBN). The works over a new tiltmeter were started in 1997. The long water-tube tiltmeter consists of two perpendicular tubes, 81 and 92 m length. The tubes are partially filled with water. Variations of the water level at the ends of tubes are measured with very high precision near to single nanometers with use interferometric method. The pictures of the interference rings are reading by the CCD-cameras, analysing and storing on hard disc of the PC-computer. The lack of drift of the long water tube tiltmeter permits on new investigations. We can expect that collected measurements allow to considerably improving accuracy of the tidal waves parameters determination as well as investigate the secular and long period variations of the plumb line. The phenomena of present movements of the tectonic plates, movements in Sudeten formation as well as rate of erosion processes are on the list of new investigations. The applications of a new tiltmeter also contain investigations over plumb line variations, generated in ocean and produced by " global greenhouse effect". The "greenhouse effect" is reason of long period and systematic variations of the plumb line as well as modulation of tidal waves (Chojnicki, 1989, 1991 and 1991) (Kaczorowski, 1989 and 1989). On the list of applications of a new tiltmeter there are also investigations of non-periodic effects of plumb line variations produced by atmospheric phenomena. An additional aspect of construction of the long watertube tiltmeter is possibility of initiation comparatives works between two difFerent kind tiltmeters. The comparison between long water tube and horizontal pendulums will allow determination of the instrumental drift of the quartz horizontal pendulums, working in Książ station since 30 years and increase scientific value of 30-years long, continuous series of observations, performed at the Książ station.
