Andarkuppam Burial Ground Pond

This pond is located in the southern part of Vichur-Eachankuzhi Road. Since it is located in the premises of Andarkuppam Burial Ground, the pond remained abandoned for many years. The Greater Chennai Corporation had identified this pond and found that the pond could be reformed as a potential water resource. Subsequently, the pond has been restored under the Chennai Smart City project funds.

Location

This pond is in Zone - 2 and located on the Andarkuppam - Redhills Road. It is located to the North of the road inside the Andarkuppam Burial Ground. The pond is located at North Latitude 13'11'37.71" and East Longitude 80'16'7.27".

Field Observation and Inferences

The pond is roughly rectangular in shape. There is no water in the pond during the time of survey. There is no revetment nor steps provided on the bund. The pond is free from encroachment and pollution. There is no specific catchment to the pond but for its own in-situ catchment. The pond is inside a well protected area with compound wall provided on all sides of the burial ground. There is no inlet or outlet to the pond provided. Based on the interaction with the local community, it is inferred that the pond use to hold water for about 9-10 months in the past, whereas now it holds only for about 5 - 6 months in a year. In the past, the pond water was used for washing and bathing by the local community.
The quality of stored water is reported to be good and fit for domestic washing. There is no weed infestation found in the water spread area. There is no storm water drain available nearby.
Based on the Total Station Survey output, it is inferred that the total area of the pond is 2423.751 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 16.04.2017 and 15.06.2010 is presented below shows no major change on the water spread area of the pond.

Pond Storage Estimation

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 4,847.5 cu.m Based on this estimate, there will be water available in the pond for almost 133 days in a year. At no point of time, the pond overflows in a normal rainfall year. The total inflow to the tank in a normal rainfall year is estimated at 4,364.12 cu.m; the total groundwater recharge will be 2,884.26 cu.m.The estimate made for an excess rainfall year ie during 2005, is given in the following Graph :

Based on this estimate, there will be water available in the pond for 268 days. The pond in its present volume does not over flows even in an excess rainfall period for the assumed catchment. The total inflow to the tank in an excess normal rainfall year is estimated at 6,048.50 cu.m; the total groundwater recharge is 2,080.3 cu.m.

Proposed Interventions

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 de-silted and cleaned in the water spread area. 

  • The bund need to be trimmed, strengthened; 

  • Revetment need to be provided. 

  • Bush clearance all around the pond and provision of a pathway on the bund to a width of 1.8m and properly fenced. 

  • Also the surface run off from the road and the open space can also 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.
