The Delhi government wants to ensure that people do not throw garbage in drains leading to the Yamuna river in the wake of upcoming Commonwealth Games and the river far from being cleaned. The government plans to build walls around the major drains to ensure that no solid waste and other garbage flow into the river Yamuna. More than Rs 100 crores has been earmarked for the work to cover the major drains leading to the Yamuna along with the beautification of the areas near the drains. The special adviser to Delhi government, Mr R. Narayanswami, and chief secretary Rakesh Mehta had inspected the major drains and their outfall to the Yamuna and had directed the flood and irrigation department to make foolproof arrangment for the upcoming Commonwealth Games. The top officials had directed that the major drains, which are falling into the Yamuna, should be protected from garbage by constructing boundary walls on both sides of the river and also the existing measures taken on bridges should be strengthened by raising wire and mesh fencing. They had identified Najafgarh drain and the supplementary drain as the main contributor to the pollution in the Yamuna. The top officials have called for fencing of all the left out portions of the drains and the non-inhabited areas. The work includes fool-proofing of the Amberali Bridge to Karaula Bridge at the cost of Rs 7.46 crores, Karaula bridge to its outfall into the Yamuna at the cost of Rs 7.30 crores, which are part of the Najafgarh drain. The design work for securing the drains has been prepared and finalised by IIT, Delhi. The work includes construction of 2.88-metre-high brick masonary wall along right side of the drain and a 3metre-high wall on the left side to ensure encroachment of the government land and garbage dumping. The plan also includes the beautification of the left bank of the supplementary drain from Wazirabad to Badli Bridge with the plantation of trees and shrubs.
