Jeff Haydon - Montgomery Watson Australia Co-Authors: Max Anderson - Montgomery Watson Australia Peter Wilson - South West Water The rehabilitation of sewerage pipelines is carried out for either hydraulic, structural or operational reasons. The planning and investigation work completed to date for the town of Camperdown in South West Water is presented as a good example of using logical processes of low cost hydraulic planning to minimise high cost field investigations. Through the use of a calibrated hydraulic sewer model the effects of applying repair, lining or replacement solutions to reduce the quantity of wet weather inflow and infiltration have been modelled. The office based modelling of various combinations of the above works, together with supplementary flow management solutions, such as offline detention storage, has provided South West Water with valuable knowledge. The Authority has used this knowledge to evaluate a range of treatment and disposal options some of which involved I/I abatement and flow containment.
