Keeping the community informed

Central Coast Council is preparing to refurbish the Vacuum Sewer System at Davistown and St Huberts Island to improve the reliability and resilience of the system.

The refurbishment works will see key parts replaced in the existing sewer pots together with the installation of a ‘pillar’ next to the pot. The installation of the pillar will allow the critical components to be located above flood water levels, ensuring that the sewer system remains effective during major weather events.

Refurbishment works will commence in March 2022 and continue through to the end of June 2022 (weather permitting).

The majority of the work will be contained within the existing sewer pots located in front yards across the suburbs. Typically there is a pot shared between two houses, meaning that not every property will require works to be completed inside their boundary. Aside from seeing tradesmen on site completing the refurbishments, these works will cause no disruption to sewer services or the community more broadly. For properties on St Huberts Island, the new pillar will replace the existing steel pillar.
