Renovation of an old main, by insertion of a medium density polyethylene (MDPE) pipe, reduces costs in excavation and reinstatement. Traditionally the inserted pipe is smaller than the existing main resulting in a reduction in flow capacity. This paper reviews the development and evaluation of a lining technique, known as Swagelining, which produces a close fit inside the existing main, thus maximising flow Capacity.
