Il presente lavoro definisce un progetto architettonico volto a mitigare la vulnerabilià idrica della zona della Valle del Belice. L’intervento scaturisce da un’indagine finalizata a coniugare l’eredità culturale con le urgenze tecniche del territorio compreso tra Salemi e Gibellina Nuova, poli nodali del dibattito architettonico contemporaneo. In Sicilia, l’acqua ha storicamente operato come principio ordinatore trasversale, agendo qua le catalizzatore di stratificazioni tecnologiche e simboliche: essa ha definito la morfologia degli insediamenti e plasmato le gerarchie sociali e rurali. Allo stato attuale, tuttavia, la senescen za delle reti infrastrutturali compromette il soddisfacimento del fabbisogno idrico locale. In questo scenario, l’analisi idrogeomorfologica e la stima della domanda d’acqua sono risultate propedeutiche alla definizione della portata dell'intervento e dell'obiettivo programmatico: ga rantire la copertura del 10% del fabbisogno idrico per uso civile. Sotto il profilo formale, è stato rilevante lo studio delle architetture legate all’acqua in contesti climatici simili alla Sicilia. Queste si manifestano nella tassonomia, in cui i ridisegni si dividono in condotti, pozzi, cisterne o fontane in base al loro rapporto con l’acqua: i condotti trasporta no l’acqua, i pozzi la captano, le cisterne la accumulano e le fontane la celebrano. L’intervento ha rilevanza su due scale. A livello territoriale, si ipotizza un condotto ipogeo ispirato ai Qanat, sistema idraulico di matri ce araba storicamente radicata nel territorio siciliano, e caratterizzato da affioramenti puntua li. L’operazione progettuale consiste in una trasposizione tipologica: diversamente dal modello originale che intercettava la falda freatica, il nuovo segno infrastrutturale capta il deflusso superficiale. Il tracciato ricalca il sedime dell’incompiuta ferrovia Salemi-Kinisia, convertita in asse pedonale; tale infrastruttura agisce come sutura concettuale tra due centri che hanno vissuto la ricostruzione del 1968 secondo logiche divergenti. Lungo questo sistema emergono tre episodi architettonici: una cisterna ipogea concepita come oasi nel punto di captazione; un pozzo articolato sui vari livelli del punto in cui Salemi aggetta sulla valle; a Gibellina, un sistema di piattaforme e fontane che riqualifica lo spazio aperto residuale. Il modello risultante si configura come un prototipo territoriale adattabile a differenti condizio ni ambientali

The project stems from an investigation aimed at reconciling cultural heri tage with the technical urgencies of the territory between Salemi and Gibellina Nuova —two pivotal nodes in contemporary architectural discourse.
