Attualità dei sistemi idrici ipogei di raccolta delle acque piovane

Abstract

The underground systems for catchment and storage of meteoric water are a type of hydraulic works with a multi-millenary history, presently used, and with very interesting future perspectives in the framework the conversion to the “green economy”. An interesting topic, related to the possible anthropic reuse of ancient meteoric water collection and storage systems, is the evaluation of the chemical interactions between water and the rocks inside which these systems are carved, and the possible superseding of maximum admitted concentrations of chemical species potentially toxic or noxious for human health. In this work, after a review of the lithological nature of these systems, we discuss the chemical character of the water they collect, using direct measures and theoretical data from the literature, giving indications for its possible anthropic uses.
