Abstract

In questo lavoro vengono affrontati due temi molto rilevanti nel dibattito eco-nomico relativo alla configurazione ottimale dei settori idrico e fognario. In par-ticolare, viene discussa la letteratura empirica internazionale che ha analizzato l?esistenza di possibili economie di scopo derivanti dalla gestione congiunta del servizio idrico al dettaglio e all?ingrosso. A questo proposito, la maggioranza degli studi esaminati tende a identificare l?esistenza di non trascurabili economie di integrazione verticale, soprattutto nel caso di operatori di medie e piccole dimen-sioni. Inoltre, viene passata in rassegna l?evidenza empirica relativa alla presenza di economie di scopo tra il servizio di depurazione e smaltimento delle acque reflue e le parti rimanenti della filiera del Servizio Idrico Integrato. Da questi lavori sembra di poter concludere che esistano di economie di scopo tra (alcune delle) componenti della filiera idrica e fognaria per imprese di dimensioni medio-piccole. In particolare, tali economie sarebbero presenti nei segmenti dove ? pi? semplice condividere taluni fattori produttivi, oltre alla competenza tecnico-manageriale, quali il segmento relativo alla potabilizzazione dell?acqua e quello del trattamento e smaltimento dei reflui. Il lavoro discute infine l?applicabilit? di tali risultati al caso italiano
