Question

The residents of Nanganallur and Adambakkam wanted to revive an environment park on
AdambakkamEri. The lake needs to be desilted and deepened and a bund is to be formed for a walkers’
path. Moreover, steps are to be taken to prevent the discharge of sewage through storm water drains and
the dumping of garbage on the lake bunds. The environmentalists say that invasive species like water
hyacinth have clogged this water body. Also, the discharge of sewage into the lake has resulted in the
growth of unwanted plants. This is blocking the air-water interface, thereby reducing the dissolved oxygen
in the water and killing a lot of fish. The water bodies clogged by the invasive species also become a
breeding ground for mosquitoes. The State Government has been requested to expedite the works for this
at the earliest.
