The Standpipe Piezometer is designed to be placed within a drilled hole to provide a filtered inlet point. The pointed PVC tip is suitable for pushing into very loose sands at the base of a borehole, a stream, or into very loose tailings or pond sediments. It is excellent for metals sampling, as it is composed of a pre-formed porous polyethylene tube set inside a perforated PVC piezometer tip. The Standpipe Piezometerr is well suited for water level monitoring, permeability measurements, construction control, de-watering drainage operations, and slope stability investigations.
