Stage 3 - Maria Island Critical Infrastructure Upgrades

Find out more

​​​The Maria Island Rediscovered project is making progress, with the public now invited to have their say on Stage 3 of the project.

​The Stage 3 proposal consists of:​

  • Construction of a new centralised Wastewater Treatment Plant (WWTP) and effluent disposal system.
  • Decommissioning and site rehabilitation of the existing WWTP.
  • Service connections (including electricity, water and sewerage) to existing serviced buildings at Darlington.
  • Upgrades to the fire water main servicing the PWS houses.
  • Upgrades to the raw water supply pipeline.
  • Dredging of the Bernacchis Creek Reservoir to pre-flood capacity (which supplies raw water).
The site is located in Darlington, within the Maria Island National Park and the Darlington Probation Station – Australian Convict Sites World Heritage Area.  

Stages 1 and 2 of the project delivered a number of upgrades to the pressure sewer system infrastructure for the Darlington precinct and service corridors. Stage 2 also saw the completion of pressure sewer system reticulation works for the public amenities on the island, reopening of the jetty toilets, and completion of a new solar array and battery storage system to provide a sustainable energy supply for the island. Completion of Stage 3 works will see the final connections of critical infrastructure works completed in Stage 1 and 2. 

The draft Reserve Activity Assessment (RAA) document was prepared in accordance with PWS advice and specialist advice.  Natural and cultural values assessments were completed to avoid and limit potential impacts.  

Once complete, the critical infrastructure delivered through the Maria Island Rediscovered project will facilitate sustainable visitation to the Island into the future.
In 2021, the Tasmanian Government allocated funding to the Maria Island Rediscovered Project to complete necessary upgrades to the critical infrastructure on the Island.​
