Perumal Koil Street Kulam

Perumal KoilKulam has been chosen for restoration by CMWSSB as part of the Sustainable Water Mission. This pond is located on the Perumal Koil Street  Assissi Nagar Link Road. It is at the Northern end of Nehru Street. A Perumal temple is located nearby the pond and hence the name. The pond is roughly rectangular in shape. There was no water in the pond during the time of survey. The pond has no steps, revetment, inlet or outlet. It was dumped with solid waste earlier.Liquid waste disposal was happening to some extent as the area surrounding the pond is fully urbanized. The pond has its own in-situ catchment. The soil is sandy in texture and light yellow in colour favouring good percolation of the stored water in the pond. Now the pond is fully restored under the Chennai Smart City project funds.

Location

This pond is in Division 27 of Zone  3 and is located on the Perumal Koil Street  Assissi Nagar Link Road. It is at the Northern end of Nehru Street. A Perumal temple is loacted nearby the pond and hence it has its name. The pond is located at North Latitude 13 9'7.47" and East Longitude 8013'55.13"

Field Observation and Inferences

The pond is roughly rectangular in shape. There is no water in the pond during the time of survey. The pond has no steps, revetment, inlet or outlet. It was dumped with solid waste earlier and at present is being removed. There is very minor liquid waste disposal happening as the area surrounding the pond is fully urbanised. At present, there is no specific catchment to the pond but for its own in-situ catchment. The soil is sandy in texture and light yellow in colour favouring good percolation of the stored water in the pond. The bund of the pond in the southern side is under partial encroachment. The pond needs immediate intervention and can be renovated and restored. Based on the Google Earth output, it is inferred that the total area of the pond is 2,710.82 sq.m and the total length of the bund is 180m. The average depth of the pond is about 2m.

 

 

Impact of Urbanisation

The imagery extracted from google earth on 21.03.2016 and 01.06.2002 is presented below shows changes in the shape of the pond indicating the encroachment on the bund.

Proposed Interventions

As total station was not done to this pond the exact extent is not available and hence run off model was not generated to this pond.

Based on the field observation and inferences, following were the list of activities proposed for renovating the pond.

  • To start with, the pond can be desilted and deepened.  
  • The bund need to be formed and strengthened;         
  • Revetment need to be provided with toe wall and binding wall along with steps.
  • Bush clearance all around the pond and provision of a pathway all around the pond to a width of  1.8m and properly fenced.
  • A recharge well of 1.2m in diameter to a depth of 3m can be provided in the pond to facilitate groundwater recharge.
