There is a small pond in the end of Nattar steet in Velachery. It is being slowly tortured for being located in a booming locality and doing a sacred service for storing precious water. As a part of torture, construction debris and garbage is dumped in its bund. It may slowly die due to the torture.
Also there is one puniyankeni(small pond) located near a amman temple in the interior of velachery. It is slightly lucky as there is a compound wall built around it. But still faces the torture of garbage being dumped.
Given a rejuvenation, both of them will faithfully and loyally help mankind.
