Tolosa Water Supply Upgrade Project

An artist's impression of the two new enclosed storage tanks

Updated May 2017

TasWater has completed the construction of two new covered water storage tanks at 317 Tolosa Street, Glenorchy.

TasWater’s $24 million Tolosa Water Supply Upgrade Project made these tanks the main water supply for Glenorchy for the coming decades, allowing for the area’s expected population growth. Water quality will also be improved, since the new water tanks will be enclosed and less susceptible to contamination than the open-air Tolosa Dam, which has reached the end of its useful life.

Although it has not supplied drinking water since 2014, TasWater has maintained the Tolosa Dam as a back up in case of emergency. With the new tanks now complete, this back up is no longer needed. Maintaining the Tolosa Dam would require significant investment to upgrade the dam to modern standards, so TasWater is working with Glenorchy City Council on a plan to decommission the dam. This means emptying the dam and lowering the dam wall so it can no longer hold water.

The Tolosa Water Supply Upgrade Project included a new pipeline to connect the tanks to the existing water reticulation network, running from the tanks to the base of the Tolosa Dam, via Tolosa Street.
