Water in the water main travels {{convert|19.3|km}} from the Bendora Dam via gravity to the treatment plant on Mount Stromlo, adjacent to the Cotter Dam pumping station, upstream from the confluence of the Cotter River with the Murrumbidgee River. Construction of the water main commenced in 1966 and was opened on 5 January 1968.
