At the interview, our Engineers introduced to the media two trenchless pipe rehabilitation technologies, namely spiral wound rehabilitation technology (SPR^TMPE) and cured-in-place-pipe (CIPP) lining.  DSD is planning preventive rehabilitation works to tackle the risks associated with ageing of drains and sewers.  Amongst them, a public works item namely “Rehabilitation of trunk sewers in Kowloon, Shatin and Sai Kung” is scheduled for commencement end this year.  DSD will employ trenchless rehabilitation technologies to reduce the impacts to public and traffic during construction.
