"In conclusion, the trial carried out for Ice Pigging showed that this method of cleaning was successful and had been shown to be economically competitive to other available technologies. Further to this, once this technology becomes commercially available throughout Australia; it has the potential to be more widely used across the network." Michael Redrup, Gosford City Council's Operations Manager

The Project - Drinking Water
Ice Pigging was used to clean 630m of cement-lined cast iron pipe. The objective being to clean the water mains and to provide measurable results to demonstrate the success of the process. SUEZ was able to provide pre and post-clean camera inspections, physical pipe samples, pre and post-NTU levels and volume of sediment removed.
Discoloured water is an ongoing battle for Gosford City council. Ice Pigging was identified by the Council's Water Operations team as the most appropriate method of removing sediments and other particles from the inside of drinking water pipes. In favour of swabbing, which they had used for many years, Ice Pigging would allow Gosford to overcome the drawbacks of swabbing.
Water bottles lined up to show the progression of dirty to clean water with the use of Ice Pigging.
