Progress against specific outcomes and actions<br />

Specific Outcome 62<br />

Continue to implement the Working Wetlands project<br />

to deliver improved water quality, volume and landscape<br />

aesthetics for the RBG Melbourne lake systems,<br />

in particular Working Wetlands Parts A and B:<br />

a. Part A comprises the harvesting of rainwater from<br />

the local urban storm-water flows on Anderson<br />

Street and Domain Road, and the construction<br />

of wetlands to treat the harvested stormwater<br />

by the removal of sediments and nutrients.<br />

The treated water will then be stored in the lakes;<br />

and<br />

b. Part B comprises the pumping of water from<br />

the lakes, filtering and treating the water, and<br />

then pumping the water into the existing<br />

irrigation system. The implementation of Part B<br />

is subject to funding.<br />

At RBG Melbourne, implementation of the Working<br />

Wetlands Project – a major stormwater harvesting<br />

and recycling initiative – continued, with progress<br />

made in the following areas:<br />

a. Construction of Working Wetlands Part A, with<br />

an expected completion date of 31 October<br />

<strong>2011</strong>: stormwater harvesting from Domain Road<br />

was completed, wetlands were constructed and<br />

planted in the Nymphaea Lily Lake, and work<br />

continued on wetland construction in the<br />

Ornamental Lake. Challenges associated with<br />

the Coode Island silt in the Ornamental Lake<br />

required some re-design of the original proposal.<br />

b. Funding for Working Wetlands Part B was<br />

approved by the Commonwealth Department of<br />

Sustainability, Environment, Water, Population and<br />

Communities, enabling commencement of the<br />

project. An Expression of Interest process was<br />

undertaken to identify a shortlist of appropriately<br />

qualified contractors for the design and<br />

construct tender.<br />

Specific Outcome 63<br />

Raise funds to cover any funding gap for<br />

Working Wetlands Part A, and potentially for<br />

Part B pending the outcome of the current<br />

Federal funding submission.<br />

In January, a construction progress report and<br />

financial acquittal was submitted to the Sidney<br />

Myer Fund and The Myer Foundation for the first<br />

instalment of their 2009 Commemorative Grants<br />

Program’s grant to Working Wetlands. Following the<br />

acquittal, the final equal instalment was received.<br />

Further regular progress reports have been provided<br />

for the Foundation’s Directors, and in May <strong>2011</strong> the<br />

Foundation’s commitment to future water security<br />

at RBG Melbourne was again demonstrated with an<br />

invitation to lodge an additional funding submission<br />

to complete the project’s budget.<br />

Significant financial contributions from two other<br />

support institutions were also received, one from<br />

the Friends of <strong>Royal</strong> <strong>Botanic</strong> <strong>Gardens</strong> Melbourne,<br />

Inc. and the other from the <strong>Royal</strong> <strong>Botanic</strong> <strong>Gardens</strong><br />

Foundation.<br />
