North Head Wastewater Treatment Plant

We are planning to upgrade the facilities at our North Head Wastewater Treatment Plant (WWTP). The benefits of the project include better quality biosolids and reduced odour from truck movements through Manly.

The project involves building two new digesters, a new dewatering facility and new sludge thickening equipment. These changes will help to ensure the reliability of our operations and that we continue to meet the requirements of our Environment Protection Licence.

We believe we have a role in protecting the environment and aim to beneficially re-use as many of the by-products of wastewater treatment as possible. Better quality biosolids can be diverted from landfill and reused in agriculture, meaning a positive outcome for the environment.

As part of our concept design we have considered the project’s environmental impacts and how they can be mitigated. More information can be found below.

    We have prepared a Review of Environmental Factors (REF) for our plans to upgrade the biosolids treatment process at North Head WWTP.

    We are seeking comment on our REF from community and stakeholders, including Northern Beaches Council, state government agencies and local community groups.

    The REF will be on display from Monday 19 March to Tuesday 3 April 2018.

    You can view the REF here or at the Northern Beaches Council Customer Service Centre, 1 Belgrave Street Manly.

    The REF outlines the project’s likely impacts on the environment during construction. As work will be located within an existing operational site and previously disturbed areas, we expect that the work will have minimal impacts to the environment.

    The new digesters, dewatering facility and sludge thickening equipment will have no visual impact. The project will have no impact on the Natural Heritage status of Sydney Harbour National Park.

    Environmental safeguards will be implemented to minimise any impacts caused by our construction activities. Once operational, we do not expect to cause any significant environmental impact.

    During construction, Sydney Water will keep the community informed on progress and let them know if work is likely to impact them.

    You can view the REF here from 19 March 2018.
