In the metropolitan area, networked water supply reached 100%, although the sewage network is not complete (Regione del Veneto, 2008c). Though recent efforts have likely lowered this rate, improvements are still needed. To some extent, this reflects generic problems that affect the water supply sector in general. The water supply sector, insofar as it relies on hydraulic technologies, entails high capital costs relative to operating costs and to the tariffs generally charged for water.
