Thamaraikulam (Shanmugapuram)
Thamaraikulam (Shanmugapuram) has been chosen for restoration by CMWSSB as part of the Sustainable Water Mission. This pond is located on the Siva Prakasam Nagar Main Road (40 feet road off Surapet Main Road). It is located to the South of the road and to the North of Tambaram - Maduravoyal - Puzhal Bye Pass Road. The pond is roughly square in shape. There was water in the pond during the time of survey. There is no revetment, steps, inlet or outlet to the pond. At present, there is no specific catchment to the pond but for its own in-situ catchment. The area around the pond is urbanized. There is an overhead tank located on side of the pond. The bund is in good condition. Lotus flowers usually grow in this pond and thus the pond was named as Thamaraikulam. One of the major advantages of this pond is that it is not polluted neither by solid waste dumping nor domestic liquid waste diversion. No major encroachment was observed. The pond was in a condition that it could be easily renovated and restored. Now the pond is fully restored under the Chennai Smart City project funds.

This pond is in Division 24 of Zone - 3 and is located on the Siva Prakasam Nagar Main Road (40 feet road off Surapet main Riad). It is located to the South of the road and to the North of Tamabaram Maduravoyal Puzhal Bye Pass Road. The pond is located at North Latitude 13- 8'24.58" and East Longitude 8010'59.38"
The pond is roughly square in shape. There is water in the pond during the time of survey. There is no revetment, steps, inlet or outlet to the pond. At present, there is no specific catchment to the pond but for its own in-situ catchment. The area around the pond is urbanized. Here is an Over Head Tank located on side of the pond. The bund is in god condition. The water spread is with Lotus and hence the pond gets its name. One of the major advantage of this pond is that it is not polluted neither by solid waste dumping nor domestic liquid waste diversion. Also no major encroachment observed as of now. The pond can be easily renovated and restored.
Based on the TSS output, it is inferred that the total area of the pond is 19,103.036 sq.m and the total length of the bund is 547.98m. The average depth of the pond is about 2m.
The imagery extracted from google earth on 16.04.2017 and 21.03.2016 is presented below shows no major change on the water spread area of the pond.

The actual volume stored in the tank during 1987 a normal rainfall year - after losses due to evaporation and recharge is given in the following graph.
The total storage of the tank in its present condition is estimated at 38,206.072cu.m Based on this estimate, there will be water available in the pond for almost 138 days in a year. The net inflow estimated for an excess rainfall year is presented below :
Based on this estimate, there will be water available in the pond for 146 days
Based on the field observations and inferences, followed by the data analysis, following were the list of activities proposed for renovating the Pond.
- To start with, the pond can be dewatered, desilted and cleaned in the water spread area.
- The bund need to be trimmed, strengthened;
- Revetment to be provided.
- Bush clearance all around the pond and provision of a pathway all around the pond to a width of 1.8m and properly fenced.
- Also the surface run off from the road can be diverted into the pond through a filter chamber.
- A recharge well of 1.2m in diameter to a depth of 3m can be provided in the pond to facilitate groundwater recharge.
