Southern Midlands

The Southern Midlands Irrigation Scheme (SMIS) is part of the Future Irrigation Project which will inform the development of the Tranche Three suite of schemes proposed by Tasmanian Irrigation.
April 2015

The Southern Midlands scheme will be situated across the Central Highlands and Southern Midlands Council regions. The scheme will also support irrigation activities in the Brighton and Clarence Council regions.

The region proposed for the Southern Midlands currently incorporates a significant number of land holdings that provide a range of agricultural products. This varies from livestock to broadacre cropping to wool to fruit and vegetables and wine grapes. The construction of a dedicated irrigation scheme will increase the area of land able to be irrigated thereby allowing changes in agricultural activity to high value commodities, trading and movement of water between properties.

Demand for 31,500 ML/season was indicated from initial Expressions of Interest sought in March 2018.

The concept design for the scheme is based on a 180-day irrigation season. The proposed scheme consists of a low lift pump station at Hydro’s Lake Echo pumping to a nearby balance tank, water is then supplied via a mini-hydro system through the Bothwell region with a lift pump station near Shiners Hill providing supply through to Jericho and Kempton. The scheme also provides an interconnection with the existing Southern Highlands Irrigation Scheme and South-East Irrigation Schemes and provides supply through to the Elderslie and Broadmarsh areas via an offtake from Bothwell.
