Vibrating Wire Piezometer is installed in a borehole using a fully grouted method. Using a traditional method involves the placement of sand pockets surrounding the piezometers, grout columns, and bentonite seals to separate piezometers at different levels.

Where is piezometer installed?

The piezometer is to be installed/constructed at the minimum of 50 m distance from the pumping well through which groundwater is being withdrawn. The diameter of the piezometer should be about 4” to 6”. The depth of the piezometer should be same as in case of the pumping well from which groundwater is being abstracted.

How do standpipe piezometers work?

The groundwater pressure pushes the water into the standpipe until the level of water inside the standpipe (h) is equal to the piezometric level (pore water pressure) in the ground at the elevation of the porous filter. That is how the piezometer water level is used and monitored.
