  abstract = {{A}rtesian aquifers offer interesting opportunities for water supply by providing a low-vulnerability groundwater resource that is easily abstracted without any installation of pumps or power supply costs. {H}owever, hydraulic tests are challenging to perform, notably where the piezometric head is above ground level with free-flowing wells not equipped with valves and open for years. {T}his paper describes a low-cost, easy to reproduce and adaptable device, the free-flowing artesian well device ({FFAWD}), which is mainly designed with a set of {PVC} tubes equipped with a pressure probe and a valve. {T}his device is used to perform hydraulic tests on free-flowing artesian wells, to measure the piezometric head of the aquifer and to compute its transmissivity. {T}he practical use of the {FFAWD} is described and a method is proposed to compute the piezometric head and the transmissivity of the aquifer from this data set (free-flowing well discharge and pressure increase measurements) with any adapted analytical solution, using the {H}oupeurt-{P}ouchan method. {A}rtefacts such as post-production effects, surge effects, and the impact of a leaky well are identified to avoid any misinterpretation. {T}he {FFAWD} was applied to the volcano-sedimentary artesian plain of {P}asuruan ({I}ndonesia). {T}he advantages and limitations of using the device, along with the interpretation methodology, are also discussed.},
