NEC has been used to rehabilitate a 4.2 km long trunk sewer in Tuen Mun, Hong Kong under live flow conditions. The work involved trenchless slip-lining of the live trunk sewer along Lung Mun Road in Tuen Mun using 2.3 m diameter glass-fibre reinforced plastic (GRP) pipe segments. Three remote-control robots were collaboratively developed to help clear the sewer of silt and obstructions and assist with lining, particularly on curved sections.
