Sewer Rehabilitation, JAL Nigam, Ghaziabad
New Bus Stand to NH-24
Sewer Rehabilitation work from New Bus Stand to NH-24. Total rehabilitation length of 6.2 km’s by cured-in-place pipe (CIPP) Technology.
A resin-saturated felt tube made of polyester, fibreglass cloth or a number of other materials suitable for resin impregnation, is inverted or pulled into a damaged pipe. It is usually done from the upstream access point (manhole or excavation). It is possible to invert the liner upstream (e.g. from the downstream access point) but this carries greater risk. It is possible to install a liner from the downstream access point, upstream to a blind end; however, this carries the highest risk of all the CIPP installation methods. CIPP is considered a trenchless technology. Little to no digging is involved in this trenchless process, making for a potentially more cost-effective and less disruptive method than traditional "dig and replace" pipe repair methods.
