Central Coast Council is investing $1.47million this financial year to upgrade and improve the performance of the Central Coast’s sewerage infrastructure,

Council Senior Manager Water and Sewer, Bileen Nel said the work is part of an $11million multiyear project to reline targeted gravity sewerage infrastructure across the region.

“The innovative technology we are using to rollout our sewerage relining project means minimal disruption to services during works and minimal environmental impact as the need to excavate is eliminated in most cases,” Ms Nel said.

“We are rehabilitating damaged pipelines by firstly clearing any blockages and then inserting a liner that reinforces the existing pipe structure, seals any leaks and significantly reduces the risk of future intrusion, particularly from tree roots.”

This region-wide project is targeting gravity sewerage mains, manholes and junctions that have been identified for renewal.

Ms Nel said tree roots and the flushing of inappropriate items were the main causes of partial and total blockages in sewerage systems.

“Tree roots certainly do impact our sewerage network, particularly in heavily wooded areas like the Central Coast.

“Flushing things that should not be flushed can also cause significant damage – please never flush cooking waste, fats and oils, cigarette butts, nappies, dental floss, sanitary items, and wipes – even if they are labelled ‘flushable’.”

Central Coast Council operates and maintains over 2,200 kilometres of sewerage mains.
