Yorkshire uses 'no-dig' technology on gravity-fed sewers

摘要

Yorkshire Water has tri-alled a world-first 'no dig' gravity-fed sewer lining system to increase the lifespan of its underground sewers by up to 50 years. The technology is expected to save the firm around £1.25 million over five years by renewing large sections of its underground gravity-fed sewer infrastructure without having to replace it.
