The Southern Highlands Irrigation Scheme commenced operations in November 2017 and services the Bothwell area in the Southern Midlands of Tasmania. Water is harvested into the Southernfield Dam from the Shannon River and delivered via 58.4km of pipe from the dam at Waddamana Road in the north to Bothwell, and south to Hollow Tree. A pipeline also runs east from Bothwell to Pitcairns Marsh.
A pump station is located south of Waddamana Road on the banks of the Shannon River. The pump station can pump to the dam, into the scheme or a combination of both at the same time. There are also two booster pumps at Bothwell and Hollow Tree.
