Welcome to Your Say

We will soon be renewing 3km of water pipes in East Fremantle, Bicton and Palmyra. This work will improve the security and reliability of the water supply to the area for decades to come. Construction work is planned to begin in late 2021 and will be completed in a staged approach which will continue through to mid-2022. More information about the timings and locations of these stages will be shared closer to construction starting.How can I find out more about the project or ask a question?<ul><li>Read up on <a href="https://yoursay.watercorporation.com.au/pipes-for-perth-east-fremantle?tool=forum_topic#tool_tab" rel="noopener noreferrer" target="_blank">project updates</a> below</li><li><a href="https://yoursay.watercorporation.com.au/pipes-for-perth-east-fremantle?tool=qanda#tool_tab" rel="noopener noreferrer" target="_blank">Ask a question</a> and we will respond<a href="https://yoursay.watercorporation.com.au/pipes-for-perth-east-fremantle?tool=news_feed#tool_tab"></a></li></ul>Find out more information on how we can <a href="https://yoursay.watercorporation.com.au/pipes-for-perth-east-fremantle?tool=news_feed#tool_tab" rel="noopener noreferrer" target="_blank">support businesses during construction</a>.

Pipes for Perth - East Fremantle

We are progressing a proposal to construct a seawater desalination plant in Alkimos. This will be on Water Corporation land - known as the Alkimos Water Precinct - located between the coast and Marmion Avenue. We already operate a wastewater treatment plant there. This services the local area and Perth&rsquo;s growing northern corridor. We are currently undertaking a <a href="https://www.watercorporation.com.au/Outages-and-works/Ongoing-Works/Alkimos-Wastewater-Treatment-Plant-upgrade">separate project</a> to upgrade this facility to keep pace with growing demand in the area.A potential desalination project in Alkimos would include:<ul class="decimal_type"><li>A 50 billion litre per year desalination plant within the Alkimos Water Precinct, with the possibility of a future 50 billion litre per year expansion</li><li>An ocean intake pipeline below the seabed that brings seawater into the plant</li><li>An ocean discharge pipeline below the seabed that safely takes brine (salty water) away from the plant</li><li>A 33.5 kilometre <a href="https://yoursay.watercorporation.com.au/33044/documents/96866">pipeline</a> to transfer drinking water produced by the plant to Wanneroo Reservoir for supply into Perth&rsquo;s Integrated Water Supply Scheme</li><li>Built-up, vegetated, sand dunes on the western side of the Alkimos Water Precinct. We will incorporate this into the existing natural dune system to minimise potential visual and noise impacts from the plant</li><li>Provision for a 4.9 billion litre per year groundwater treatment plant and sustainable coastal bores</li></ul>Working with the communityWe engaged the local community about a possible seawater desalination plant in Alkimos in 2018. There is a high level of support from locals and the wider Perth community for desalination as a rainfall independent water source in Alkimos.We invited the community to learn about the project and provide feedback. This was through a series of local face-to-face events and through our online platform. Learn more about our <a href="https://yoursay.watercorporation.com.au/33044/documents/96864">conversations with the community</a>. We have incorporated the feedback and ideas we received. We&#39;ve completed more studies and refined potential construction methods and precinct designs. We&rsquo;re committed to minimising any potential disturbance to the local community. We have already used initial feedback to <a href="https://yoursay.watercorporation.com.au/33044/documents/96865">reduce potential visual and noise impacts</a>.Protecting our environmentWe have conducted extensive research to minimise environmental impact. The location and construction of the offshore pipelines required has been investigated. These will bring seawater in and safely take brine away from the plant. Read more about how we are planning to <a href="https://yoursay.watercorporation.com.au/33044/documents/96868" rel="noopener noreferrer" target="_blank">protect the marine environment</a>.Protecting Aboriginal HeritageAn Aboriginal heritage survey has been completed over the development area footprint of the proposed plant and pipeline route to Wanneroo Reservoir. The survey indicated that the plant site does not impact heritage sites as defined under the existing Aboriginal Heritage Act 1972. A few registered Aboriginal heritage sites were identified close to the proposed pipeline route and Water Corporation is reviewing the pipeline route to avoid those sites. An Aboriginal Heritage Management Plan for the project is being progressed and Water Corporation will engage with Traditional Owners on the development of an ASDP Aboriginal Engagement Strategy. This strategy will set the framework for engagement with Aboriginal stakeholders and identify opportunities for Traditional Owner participation in project planning, procurement, employment and heritage.More informationPlease also refer to <a data-fr-linked="true" href="//www.watercorporation.com.au/newdesal">www.watercorporation.com.au/newdesal</a>

Alkimos Seawater Desalination Plant

Since 2009 we have been working to create an integrated water supply scheme that provides secure, high quality water to the towns of Nannup, Bridgetown, Hester, Boyup Brook, Greenbushes, Balingup and Manjimup.Known as the Warren Blackwood water supply scheme (WSS), historically it relied on independent local dams. Now it is an integrated scheme with groundwater supplementing dams due to the impact of climate change.In 2022, the scheme will be expanded to include the communities of Kirup and Mullalyup with the completion of the <a href="https://www.watercorporation.com.au/Outages-and-works/Ongoing-Works/Greenbushes-to-Kirup-pipeline">Greenbushes to Kirup pipeline</a>. The scheme may also be expanded to include supply to <a href="https://www.watercorporation.com.au/Outages-and-works/Ongoing-Works/Pemberton-source-investigations" rel="noopener noreferrer" target="_blank">Pemberton</a>, Northcliffe and Quinninup.Water Corporation is reviewing the water source development plan for the Warren Blackwood scheme due to climate change, declining water quality, conflicting land use within water source catchment areas and increasing demand.The scheme currently relies mostly on groundwater from the region&rsquo;s deepest aquifer, the Yarragadee aquifer, via a bore near Nannup. A further 25% of water supply comes from the larger local dams - Millstream Dam, Manjimup Dam and Tanjannerup Dam. Originally, the bore was only used for backup supply, but now it is the main source.

Warren Blackwood water supply planning

Between May and November 2022 Water Corporation will renew 2.1kms of ageing water main on Beaufort Street between Walcott Street in Mount Lawley and Dundas Road in Inglewood.<a href="https://yoursay.watercorporation.com.au/beaufort-street/survey_tools/register-for-updates111" rel="noopener noreferrer" target="_blank"> </a>Work will be carried out in a three stage approach to minimise traffic impacts and to maximise construction efficiency. Each stage will take up to eight weeks to complete.<ul><li>Stage One: Walcott Street to First Avenue</li><li>Stage Two: First Avenue to Central Avenue</li><li>Stage Three: Central Avenue to Dundas Road</li></ul><img src="https://s3-ap-southeast-2.amazonaws.com/ehq-production-australia/2161ece964cd090695da09cf2a568b9aab77d3c8/original/1643342471/f25bae2bb704051f0ed058e80690da94_Beaufort_St_%28550px_wide%29_v3.png?1643342471" style="width: 399px;" class="fr-fic fr-dib fr-fil"> During construction, both lanes of Beaufort Street (Northbound) will be closed within the stage area and detours will be in place. Beaufort Street (Southbound) will remain unchanged.Access will largely still be provided to side streets and car parks during the work, from the Southbound lane.While one stage of work is being completed, the other two stage areas of Beaufort Street (Northbound) will remain open, however detours will still be in place. Detour maps, including access points and timing will be provided soon.All construction work will be undertaken within the road, so pedestrian access to businesses will remain open throughout the period. For more information on the pipe location and details, please see our FAQs.As part of this project we&rsquo;re committed to supporting local businesses during construction. We are currently liaising with a small project working group, with the aim of creating initiatives to help keep visitors to the area.Keep an eye out for us, as we will be in the community over the next few months to talk to you more about the project and answer any questions you may have.
