Objectives The objective of this project is to trial equipment for water removal from the top of the main without the need for BA equipment, ensuring the water from within a specific section of the main is fully removed and allows engineers to install a PE siphon directly on the network without installing a water collection pit at a relatively low cost. The success criteria for the project is to trial and test a Top Tee siphon adaptor and show that: Removes water from a PE main in a controlled environmentCan be applied directly on to a PE network resulting in a reduction of required fittingsReduces the requirement for larger excavations & removes the need for a water collection pitRestores gas supply to customers in a shorter time frame. Product is a cheap cost solution for removing water over traditional methods.
Abstract Heavy flooding and events such as burst water mains cause pipelines to take on water. Water ingress is a problem that NG faces on its distribution network. Water ingress can lead to loss of system pressure and loss of supply to customers. When emergency incidents occur, the current method of removing water from multiple streets requires an excavation to be made to uncover the section of pipe, installation of a pit to allow water to gather, siphon out the water, and once removed the saddle is then plugged and the excavation back filled. This has to be done in multiple streets to remove the water from an entire area. This can be very time consuming and keeps customers off gas until the water is removed. National Grid working with Gas Leakage Solutions are going to trial and test a Top Tee Siphon adaptor that can withdraw water from the top of PE mains without the requirement for Breathing Apparatus, as a low cost solution compared to traditional methods and other techniques on the market. Network Maps will be utilised to identify low points in the areas, with altitude readings from our ESRI system to pin point locations for excavation and use of this product.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
