North Head Biosolids Upgrade Project

Now that the two new digesters are finished, we need to remove the tower crane from our site.

We'll need to dismantle the crane and remove it using five semi-trailer movements. This means there will some heavy vehicle movements to and from the facility between 6 am and 5 pm on Saturday 21 October. If we aren't able to remove the crane on Saturday 21 October, we'll defer the work to Saturday 28 October..

We’ll make every effort to minimise impacts on our neighbours during this delivery and avoid unnecessary loud noises, however the movement of the trucks for this brief period will be noisy.

We recently completed an important milestone for our Biosolids upgrade project – construction of our two new digesters is now finished!

Standing over 14 metres high, our work to build the two new digesters involved pouring over 1,300 cubic metres of concrete in ten stages. This was done over eight months between August 2022 and March 2023.

The two new digesters will increase the processing capacity of the facility from 40 tonnes to 70 tonnes of sludge per day by 2043 and contribute to reusing 100% of biosolids created as fertiliser on farms in NSW.

Our next steps are to install new fittings and equipment to support the two new digesters as well as completing some tests and checks to get them ready for use.

The aerial picture shows our two new digesters recently installed.

We've completed nine of the 10 concrete pours for the new digesters so far and our next pour is planned for Tuesday 14 March, weather permitting. If we’re not able to complete the pour on Tuesday, we will defer the work to Wednesday 15 March

We need regular deliveries of concrete throughout the day, so there will be frequent truck movements to and from the facility:

• during school zone hours (between 8 am and 9.30 am and 2.30 pm and 4 pm)
• between 6 am and 7 am in the morning.

We've completed eight of the 10 concrete pours for the new digesters so far.

If we’re not able to complete the pour on Wednesday, we will defer the work to Thursday 23 February.
