Late last year, after nearly eight years of operation, the pipes servicing a Port Macquarie Reclaimed Water Treatment plant that recycles sewerage for domestic water use needed a thorough clean, along with other parts of the Council's potable water system.Port Macquarie-Hastings Council engaged SUEZ environnement Australia to undertake the project using a method of cleaning water pipes known as ice-pigging.

It has been found to be significantly more effective, efficient and environmentally friendly than traditional techniques.
