Hyderabad: For the first time in South India, the Hyderabad Metro Water Supply & Sewage Board (HMWSSB) was using a trenchless technology to repair and restore decades old sewage pipelines in the city, said MA&UD Minister KT Rama Rao.
Inspecting the Cured in Place in Pipe (CIPP) technology being put to use by the water board at NTR Gardens here on Wednesday, Rao said the technology facilitates restoration of ageing pipelines without the need of digging and the challenging task of replacing the old pipelines with new ones could be avoided.
The conventaional way was a cumbersome process that also caused hardships for the citizens in the form of traffic restrictions. Using the CIPP technology on experimental basis, the HMWSSB has taken up works for 1.5 km stretch from the sewerage treatment plant to GHMC head office at a cost of Rs 18 crore and if this yielded desired results, the entire 120 km main trunk line in the city would be revived using it, Rao said.
Being used in other countries, the new technology ensures durability of pipelines for 40 years to 50 years. The Union government has the responsibility to encourage adoption of newer technologies for improvement of basic amenities in the cities, he said added that the Centre was imposing 30 per cent custom duty on material used for CIPP. “We will request the Centre to reduce the duty,” the Minister added.
