Our Community Charter

WaterNSW is committed to ensuring the community is provided with clear, accurate and concise, information about the Warragamba Dam Raising Proposal in a timely manner.

Our engagement and relationships with the local community are essential in informing the environmental assessment.

We aim for open two-way conversations and easy transfer of information between WaterNSW, the wider community and other stakeholders.

Engagement to date

Since mid-2017, in preparation for the 2021 Public Exhibition of the EIS, we have had conversations with hundreds of stakeholders and communities throughout the Hawkesbury-Nepean floodplain and around, and upstream of Warragamba Dam, including but not limited to:

  • Briefings to 10 councils in the region including Camden, Hornsby, Wingecarribee, Penrith, Liverpool, The Hills, Blue Mountains, Wollondilly, Blacktown and Hawkesbury
  • Formal briefings for the Greater Blue Mountains World Heritage Area Advisory Committee
  • Briefings for special interest groups including Local Government Advisory Group and Yerranderie Management Committee
  • Around 20 scoping interviews with government agencies, emergency service providers and community stakeholders for the proposal’s Socio-economic Impact Assessment (SEIA)
  • Phone and online survey invitations to over 300 community and service groups, particularly those interacting in flood events with vulnerable communities
  • Presentations at meetings of the Indigenous Land Use Agreement (ILUA) Consultation Committee of the Gundungurra Tribal Council
  • Briefings to and involvement in survey work for Registered Aboriginal Parties
  • Coordination of catchment special area site visits for the Colong Foundation for Wilderness and Aboriginal stakeholders
  • Briefings for Yerranderie Management Committee
  • Contact with owners of more than 600 properties in the proposal study area to enable collection of survey data for noise, geomorphology, Aboriginal Heritage and biodiversity studies
  • Six pop up stalls at shopping centres and events throughout the region
  • Displays at 10 locations which helped to keep local communities informed as the proposal progressed
  • Responding to phone calls and email questions about the proposal
  • NSW Office of Environment and Heritage briefings
  • NSW Department of Planning and Environment briefings
  • Commonwealth Department of Environment and Energy briefings
  • Briefings with Local and State Government representatives.

These activities have shown that there is a high level of community interest in the proposal. Some people have raised concerns about potential environmental impacts. Others strongly supporting the proposal are concerned it is not progressing quickly enough to reduce the risks to people and their homes downstream if it floods.

We have conducted a series of phone and web surveys with groups and agencies that particularly interact with community members who are vulnerable in flood situations and face-to-face surveys with a variety of businesses about the potential effects and benefits of the proposal. The responses have been used to inform the Social Economic Impact Assessment for the Environmental Impact Statement.

Also, since 2014, the Hawkesbury-Nepean Valley Flood Management Taskforce and more recently the Hawkesbury-Nepean Valley Flood Risk Management Directorate have undertaken a series of engagement activities with key stakeholders and the community on the Hawkesbury-Nepean Flood Risk Management Strategy, including an overview of the Warragamba Dam Raising proposal as a key element. More information, including the Flood Strategy, is available online at:
