Coimbatore Smart City tanks overrun by weed infestation
The Hindu“When I visit Valankulam for my daily walk, I am usually welcomed not by serene waters, but by a thick carpet of water hyacinth beneath which, I assume, there still is water somewhere,” a frequent visitor of the tank said. These, along with Krishnampathy, Selvampathy and Kumaraswamy tanks, form the seven Smart City tanks of Coimbatore. “The proliferation of water hyacinth not only disrupts the wetland ecosystem, but also acts as a breeding ground for mosquitoes and flies, which can spread bacteria to nearby human habitats, while also posing a threat to both resident and migratory bird populations frequenting the tank,” said Mouinudeen, a biologist Apart from Valankulam, most tanks do not have functioning sewage treatment plants despite the facilities having being built in 2021. “We have raised the issue several times with authorities, but no repair work has been undertaken,” said Babu, head of the Slevachntamani Tank Walkers’ Association.
