The utilisation of underpressure electro-fusion Branch Saddles in gas and water distribution mains is well known and documented. To date the largest known Branch Saddles have been used for offtakes not greater than 125 mm . The advent of much larger underpressure Branching Saddles has enabled the industry to significantly reduce the cost of providing services when compared with the traditional methods of introducing a tee section by cutting into existing mains, operating by-passes and having to contend with large excavation, necessitating additional re-instatement costs. This paper provides the information that indicates the savings to be made by employing the new Large Diameter Branching techniques.
