Clontarf to North Head section (Section 1)

We're continuing to refine our plans to desilt the next section of the NSOOS from Clontarf to North Head (Section 1).

You may recall from our last newsletter, as part of our preparation, we’re building an underground access cavern at the North Head facility. This involves excavating sandstone rock about 60 metres underground. The cavern will serve as a new NSOOS access point for our specialist desilting equipment and crews.

While the NSOOS rehabilitation is underway, we’ll temporarily redirect wastewater to the Northside Storage Tunnel (NST). To support this, we’re continuing with our planning to clean out silt from parts of the NST underground at our North Head facility so it can continue operating as a diversion to the NSOOS.

This important work will help to pave the way for future sections of the NSOOS to be rehabilitated and once completed, will increase capacity, assist in preventing overflows, and extend its lifespan.
