§ Mr. Skeetasked the Secretary of State for the Environment to what extent the system of pipe jacking, under which pipe is thrust through the ground by hydraulic pressure as opposed to cut and cover techniques, is used for sewerage in the United Kingdom.
§ Mr. Giles ShawThe technique of pipe jacking is a well-tried system of installing underground pipes and conduits. It is used by the water industry where site circumstances and local subsoil conditions are favourable, but no separate records are maintained of the proportion of water main or sewer pipeline lengths constructed by this method.
