Regulators are demanding greater efficiency in the way water infrastructure is managed and water authorities have limited resources available to achieve this. As a result, alternatives to traditional asset management approaches are being developed. From a customer and stakeholder perspective, use of this technology will result in a much faster renewal time (meaning less time connected to temporary services), reduced disruption during the works period, and reduced reinstatement. Up until now water main renewals have been characterised by online and offline replacement of the existing main with a new pipe or liner forming a pipe within a pipe.
