The Gurugram Metropolitan Development Authority (GMDA) on Sunday said it has replaced most of the damaged sewage pipeline at the Iffco Chowk sinkhole, barring a small four- to five-foot patch that has been kept open to allow desilting of the sewer line. The authority will test the new pipeline for leaks on Monday, after which the remaining patch will be closed and the damaged road repaired, officials added.They said it will take around three to four more days to completely repair the road, after which the sinkhole area will be filled and the road restored.
Two service lanes of the highway were barricaded following the incident and have remained closed since. A 1,000 mm master sewer line had collapsed at the Iffco Chowk service lane on the Delhi-to-Jaipur side on Tuesday, August 25, creating a large sinkhole and causing panic among commuters and congestion on the road. Following the collapse, GMDA began dewatering and diversion work before starting pipeline rehabilitation on Thursday, August 27.
Officials said that once the pipeline is fully repaired and leak testing is completed, the stretch will be handed over to NHAI for road reconstruction. Following the incident, GMDA officials said they have started surveying sewer pipelines across the city, and those found to be old and in dilapidated condition will either be upgraded or replaced.
The repair of the road was earlier estimated to take another five to six days, potentially allowing the barricaded service lanes to reopen by the first week of September.
