Gurugram, Oct. 6 -- Garbage from Delhi is allegedly being brought across the border and illegally dumped in Gurugram even as the Municipal Corporation of Gurugram (MCG) has intensified field monitoring to tackle persistent sanitation problems across the city. Gurugram police arrested 10 people on Sunday evening and seized seven vehicles, including canters and tractor-trolleys, in a crackdown on a network allegedly transporting garbage from Delhi into the city. Four cases have been registered - two at Bajghera police station and one each at Udyog Vihar and Rajendra Park police stations. Police said they are yet to establish where in Delhi the waste originated, but a preliminary investigation found that it was being brought into Gurugram in commercial vehicles before plastic was separated and transported elsewhere. Gurugram police spokesperson Sandeep Kumar said investigators are trying to establish the entire chain, including those arranging the transportation, the routes used, the locations where the remaining waste was dumped and those receiving the segregated plastic. "We are examining the role of vehicle owners, operators and others involved in segregation and further transportation," Kumar said. Investigators are also examining the ownership and checking whether owners were aware of the alleged illegal activity. The case comes amid continuing complaints of garbage, construction and demolition (C&D) debris and horticulture waste being dumped on vacant plots, roadsides and other vulnerable locations across Gurugram. In July, MCG teams had intercepted vehicles allegedly carrying waste from Delhi near the Udyog Vihar and Kapashera borders. Against this backdrop, municipal commissioner Pradeep Dahiya on Monday directed all additional municipal commissioners and joint commissioners to spend two hours in the field every day, from 10am to noon, inspecting sanitation work and addressing problems. Senior officials inspected garbage vulnerable points (GVPs) in different parts of the city on Monday, reviewed waste lifting and directed sanitation teams to ensure regular cleaning. MCG also made sprinkling of lime mandatory after garbage is removed from GVPs and ordered regular monitoring. The Delhi-Jaipur Expressway, Sector 29 and adjoining areas have been identified for special monitoring. Officials have been directed to ensure that C&D waste, horticulture waste and other garbage found in these areas are removed immediately. Dahiya also asked officials to remain in touch with elected representatives, ward committee members and resident welfare associations so that local sanitation problems can be identified and resolved quickly. Gurugram generates around 1,400 to 1,500 metric tonnes of waste daily, while civic authorities have repeatedly struggled to prevent garbage from returning to cleared dumping points....
