Campvale catchment

Port Stephens Council and Hunter Water Corporation have been working together on the Campvale catchment project.

Finding a solution has been challenging as we need to balance our desire to reduce flooding periods with making sure water quality leaving Campvale Drain is good enough to enter Grahamstown Dam, our drinking water supply.

Following extensive investigations and technical modelling, a proposed solution has been developed that balances the competing requirements. The proposal involves regular maintenance of the drain and either modifying or pumping around, the area known as ‘the pinch’ to increase the water flow rate down to Campvale pump station. This would reduce the frequency of flooding events occurring and of particular interest would be that there would be a 75% reduction in flooding events where inundation lasts longer than 10 days.

Following a pause brought on by Covid-19, Hunter Water and Council re-engaged with the community in July / August 2020 and received feedback on the proposed solution. Following further engagement with key stakeholders, such as Medowie Progress Association and the local MP, the preferred solution is being further investigated.

These further investigations will include hydraulic modelling, water quality assessments, a review of contamination risks, a review of environmental constraints, and preparation of cost estimates in order to confirm the preferred option. It is envisaged that the next phase of this project will be complete in the latter half of 2021.

Thereafter a plan will then need to be developed to seek funding for the design and eventually funding for implementation.

Consultation and engagement has continued with key stakeholders who provided comment during the survey and indicated their interest.
