Why are the Gosford CBD water and sewer upgrades important?

A major upgrade of Gosford’s water and sewer infrastructure is required for a number of reasons including:

  • significant forecasted population growth
  • increased number of approved dwellings
  • planned and forecast high-rise developments to be used for a range of purposes including residential, business, health and education
  • development of non-residential floor space and to enable efficient and sustainable redevelopment to occur within the CBD
  • fostering economic growth by enabling development opportunities that create local jobs and reduce the need for Central Coast residents to commute to work 
  • maximizes the usage of existing utility infrastructure 
  • required to position Gosford as the capital of the Central Coast in accordance with the expectations of the NSW Government as per the Central Coast Regional Pan 2016. 
Are there any impacts because of the current Gosford CBD water and sewer upgrades?

Yes, there will be some short-term pain but the long-term gains will be worth it. Whilst we acknowledge there will be some impacts, Council is making every effort to minimis these by:
