Interflow has started rehabilitation and repair work in the Northern Suburbs Ocean Outfall Sewer (NSOOS).
The NSOOS is a large wastewater tunnel that is over 28 km long and is vital in keeping our waterways clean.
Interflow have been contracted by Sydney Water to remove the silt and debris that has built up within the tunnel over the years as well as resurfacing the walls and roof which have deteriorated. It will ensure the NSOOS continues to protect public health and the environment for many years to come.
