The Tungatinah Power Scheme is located in central Tasmania, approximately 2 hours drive North West of Hobart on the edge of the Tasmanian Central Plateau. Up to 55 cubic metres per second (m3/s) of water flows from a man-made lagoon on the edge of the central plateau to the power station in the valley below. The scheme was completed in 1957. The scheme was fitted with an intake gate, which stops the flow of water out of the lagoon, as a safety precaution. This is typical of hydro power stations which involve the movement of large volumes of water at high pressure. Problems with the existing gate led eventually to the decision to replace it. Hydro Tasmania recognised the cultural significance of the gate at the outset of the project. The gate was subsequently assessed through the Cultural Heritage Programme and found to have significant heritage value. This meant that new work was to avoid significant alteration to the existing gate. This paper describes the process whereby the existing geometry of the intake area was utilised along with the existing gate to allow the addition of a new radial gate and retention of the existing historic gate. This provided the reliability expected of a modern facility without impacting on a special part of Tasmania's engineering heritage.
