The common argument against the utilisation of SPIS is that this technology goes hand in hand with overexploitation and eventually depletion of limited water resources such as groundwater. Concerns are based on the following reasoning: SPIS lead to free pumping and hence an overexploitation of groundwater reserves is inevitable or at least very likely.
From a resource economist perspective, this argument is known as the Herder Problem or “the Tragedy of the Commons”  first described by Hardin in 1968: If there is a finite common-pool resource (e.g. groundwater) where it is difficult and costly to exclude potential users, this resource will eventually be exhausted because the rational individual will maximise his/her own utility rather than conserving the resource for the benefit of all. Meaning that an open-access resource will inevitably be over-exploited unless access and use of this resource are restricted by some form of governmental regulation or the allocation of property rights
