Residents informed the elected representative that 40-60 feet wide roads have now been shrunk to a mere 20 feet, due to encroachments. Ravi M, Secretary, Sri Sarvamangala Nagar Residents Welfare Association, said, “We also asked the officials to ensure that the roads, which have been encroached upon by houses, are made free from these obstructions. The narrow roads make it difficult for school buses and water lorries to traverse, creating congestion during peak hours.” Lack of underground sewage network means that storm water drains turn into illegal sewer lines. In addition, there is inadequate flood checking mechanisms in the locality, said Dayanand K, a civil engineer. “We want the underground drainage network process to be accelerated. The proposed flood channel from Selaiyur lake to Mahalakshmi Nagar, and from there to Sembakkam lake should be completed. The work on the flood channel has been done for 300 metres but stopped due to encroachments on the road. We have suggested the installation of a flood pumping station, which is common in other countries.
