Bryn Estyn Bryn Estyn Water Treatment Plant Upgrade

What's this project all about?

The Bryn Estyn Water Treatment Plant (WTP) is Greater Hobart’s primary source of drinking water, providing around 60 per cent of the water supplied to customers in the Hobart, Glenorchy, Clarence, Brighton, Derwent Valley, Kingborough, Sorell and the Southern Midlands municipalities.

Located at Plenty in the Derwent Valley, the Bryn Estyn WTP was originally constructed in 1962, with capacity augmentations completed in 1972 and 1992. Over the last two years, TasWater has completed upgrades and expansions of the plant to ensure it can continue to provide high-quality drinking water and meet projected demand in Greater Hobart for years to come.

With a budget of $243.9 million, the upgrade at Bryn Estyn is the largest capital works project in TasWater’s history.
