Andarkuppam Burial Ground Pond

Andarkuppam Burial Ground Pond

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 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

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.
