New Delhi, Dec. 28 -- Days after two teenagers were arrested for allegedly drugging, tying up and killing an 18-year-old before dumping his body at the Haiderpur Water Treatment Plant (WTP), Delhi Police on Friday said 35 bodies have been recovered from the facility so far this year, the highest count in the last four years. Police said that around two to three bodies are recovered every month. Senior officers said bodies frequently reach Haiderpur through the Munak Canal, which carries raw water into Delhi from Haryana. "There are no filtration nets along most stretches of the canal before it reaches Delhi. As a result, bodies from Haryana and several parts of Delhi are often swept into the Haiderpur plant, where they get trapped in the filtration system," an officer said. The Munak Canal is a 102-kilometre-long aqueduct that terminates at this plant. Police said that as bodies from Haryana take multiple days to reach the plant, nearly all of them decompose beyond identification and most of them remain unclaimed. Of the 35 bodies recovered this year, only 20 have been identified, police said, adding that the deaths include cases of natural causes, drowning, suicide and murder. Police on Sunday said they have asked the plant authorities to increase surveillance and deploy additional guards. As reported earlier by HT, the Haiderpur WTP has long been a grim endpoint for missing persons from Delhi and Haryana....
