Casagrande Piezometer

Low cost easy to use PVC piezometer with long term reliability and excellent corrosion resistance


The Casagrande piezometer is used in standpipes or observation wells to monitor piezometer water levels or groundwater levels. Construction is from durable perforated PVC body with an inner filter element with 70 micron pores.

The unit is normally connected to PVC pipes and installed in boreholes. Standpipe piezometers or observation wells with Casagrande tips are most advantageous in high permeability soils where time-lag and high volume displacement are not critical.
