Hillston and Goolgowi soils are prone to movement due to changing moisture content.
In Hillston, Council has commenced a program of re-lining defective sewerage pipelines. Re-lining is the preferred option due to the cost of replacing deep pipelines, some of which are more than 5 metres underground. The re-lining process inserts a new secure plastic lining and is carried out by specialist contractors.
Council has completed around 200 metres so far at a cost of nearly $50,000.
Further sections will be completed in 2011/12 and 2012/13.
