Vadaperumbakkam Pond is located on the Andarkuppam - Redhills Road in Balaji Nagar. The pond has its own in-situ catchment. Now the pond is fully restored under the Chennai Smart City project funds.
AREA: 2832.802 Sq.mtrs ZONE: 2 DIVISION: 17
This pond is located in Division 17 of Zone 2 and is on Andarkuppam - Redhills Road in Balaji Nagar. It is located to the East of the road. The GCC divisional office is located on the southern side of the bund. In the Western bund there is an Amman temple located. The pond is located at North Latitude 1310'33.21" and East Longitude 8013'4.22"
The pond is irrugalar in shape. The pond is filled with water during the time of survey. Sullage from the neighbourhoods is diverted into the pond. The pond is also encroached by the temple and surrounding residences. Part of the bund could not be seen. Construction debris is being dumped at one side of the pond. It is infested with water hyacinth. Though the pond has an inlet from the storm water drian, the darin carries sullage water which gets fully drained into the pond.
The pond is under highest level of destruction with dumping of solid waste, diversion of sullage and encroachment. Also it is affected by severe weed infestation. As it is severely polluted the water is not in use by the community. The pond infact has become a nuisance structure for the community as it becomes a place for mosquito breeding and emanates foul smell.
The imagery extracted from google earth on 21.03.2016 and 31.08.2001 is presented below shows major change on the water spread area of the pond.

Based on the field observations and inferences, followed by the data analysis, following were the list of activities proposed for renovating the Vadaperumbakkam Pond near Divisional office.
-
To start with, the sullage diversion into the pond should be stopped. At this stage this would be a tough task to perform as it would lead to local unrest in terms of disposing the sullage water. Hence the source from where the sullage emanates should be addressed by introducing soak pits at the house hold level.
-
The existing water should be dewatered and disposed.
-
The pond should be desilted and water hyacinth removed.
-
The bushes all around the bund should be removed and the pond should be provided with fencing and protected from further encroachment.
-
Dumping of solid waste should be stopped.
After completing the above tasks it is better to retain the water body as such for 2 3years after which the water body can be converted into a water harvesting and recharge system. Introducing recharge system at this stage would lead to the pollution of groundwater and hence it is not recommended.
Provision of revetment and steps can be considered at later stage as the pond cannot be brought into immediate use at the present condition.
