The Revierwasserlaufanstalt Freiberg (approximately: "Freiberg Mines Water Management System") or RWA Freiberg, was a historical water management system that delivered driving water to the Freiberg mines in the time of the German Electorate and later Kingdom of Saxony. Today the system is used to supply drinking and industrial water and is operated by the Saxony State Reservoir Office (Landestalsperrenverwaltung Sachsen). The Revierwasseranstalt Freiberg has been selected as a candidate for the future UNESCO World Heritage Site of the Ore Mountain Mining Region (Montanregion Erzgebirge).
