    Piezometers are used to measure groundwater levels and pressures. They are typically small-diameter observation wells made of PVC that can represent hydraulic head at a point in an aquifer. Piezometers have applications in monitoring pore water pressures during construction projects to ensure safety and evaluate slope stability. They are installed by lowering them into boreholes and backfilling the entire borehole with grout. Piezometers provide important early measurements of groundwater levels.

    PIEZOMETER
    OBJECTIVE
    To measure the hydraulic head of
    groundwater in aquifers
    To measure the pressure of a fluid
    at a specific location in a column.
    INTRODUCTION
    a small-diameter observation well used to
    measure the hydraulic head of groundwater
    in aquifers.
    also be a standpipe, tube, vibrating wire
    piezometer or manometer
    Piezometer should ideally have a very short
    screen and filter zone, so that they can
    represent the hydraulic head at a point in the
    aquifer.
    Definition

    Piezometers are generally 2 inch


    (5.08 cm) plastic (PVC) wells which are
    used to calculate ground water flow
    directions and to sample water quality
    at different depths of an aquifer.
    APPLICATIONS OF PIEZOMETER
    Monitoring pore water pressures to
    determine safe rates of fill or excavation.
    Monitoring pore water pressures to evaluate
    slope stability.
    Monitoring dewatering systems used for
    excavations.
    Monitoring ground improvement systems,
    such as vertical drains and sand drains.
    Monitoring pore pressures to check the
    performance of earthfill dams and
    embankments.
    Monitoring pore pressures to check
    containment systems at landfills and tailings
    dams.
    TYPES OF PIEZOMETERS

    Types Of Vibrating Wire Piezometers

    Heavy-Duty
    Push-In PIezometer
    Piezometer
    Low-Pressure Vented Pressure
    Piezometer Transducer
    Installing Piezometers
    To install a piezometer:
    It eliminates the conventional sand filter
    and bentonite seal.
    The piezometer is lowered into the
    borehole, sometimes tied to a grout pipe,
    and the entire borehole is backfilled with a
    non-shinking, low permeability grout.
    CONCLUSION
    Piezometer is a important test to measured
    the hydraulic head of ground water in a
    aquifer
    This can provide an early observation about
    ground water level
    The objective of the test is to avoid collapse
    soil and movement of soil.
