A standpipe tube with a porous piezometer tip connected at its lower end is installed in a borehole. Alternative types may be driven or pushed into soft soil, and different tip designs are available to suit various types of ground.

For borehole installations, bentonite and grout are used to seal the borehole above the tip. Groundwater can enter the tube only via the tip. Depth to the water level is measured with a water level meter.

The water pressure corresponds to the height of the water surface in the standpipe above the piezometer tip. A bourdon pressure gauge connected to the top of the standpipe will be required to measure artesian heads.

Ideal piezometer to ascertain the piezometric level during routine site investigation.
Simple low cost system.
Standpipes can be installed and head readings taken in boreholes to depths in excess of 200m.
Drive-in piezometers can be installed to depths in excess of 10m in soft soils (shear strength less than 20 kPa)
Ideal for long term readings in high permeability ground (greater than approximately 10-6m/s).
