Nanganallur Temple pond is a local pond owned by Revenue Department and maintained by GCC.  The water body comes under Nanganallur village in Alandur zone. SWD of the surrounding area is connected to the water body and serves as the inlet sources. There is no proper outlet for the water body. Water is greenish in colour. The pond is not connected to any upstream and downstream water resources. No proper outlet is found.  The pond gets storage during the monsoon rains.  Benefits from the implementation of this project include improvement of water quality by providing constructed wetland and aquatic floating island. Due to de-silting and refilling the pond with puddle clay, water will be made available throughout the year and hence, fish culture will be developed. With proper counseling and guidance, the Residents Association will take care of the pond and hence, water body will be protected.  The pond has been restored under the Chennai Smart City project funds.
