This pond is in Division  16 of Zone -2 (Manali) and is located on the Andarkuppam - Redhills Road. It is located to the North of the road. There is a small Vinayagar temple loacted by the side of the pond. The pond is bounded by road in South North and East and by residential plots in west. The pond is located near the Kamarajapuram Bus Stop. The pond is located at North Latitude 13 11'31.19" and East Longitude 80 15'26.48".

The pond is roughly rectangular in shape. There was meager mount of water in the pond with lotus flowers observed during the time of survey. It is a sunken pond. The major components of the pond such as water spread and bund are in good shape and there are no encroachment observed in the water spread. Minor encroachment started in the western part of the bund. The pond is in good shape without any pollution of domestic solid or liquid waste dumping / diversion. There are no steps or revetment provided in the pond. The bunds are well stabilized. There is storm water drain provided on the Andarkuppam Redhills road and a diversion from the drain to the pond has been made. There is an inlet available to the tank from the north western side which carries the surface run off from the vacant areas located to the north of the pond. Interaction with the local community revealed that the pond has water for about 9- 10 months in a year. The pond was used by the community for bathing and washing purpose. Shallow openwells and borewells are the common groundwater extraction structures in the area. Based on well inventory conducted in and around the pond, it is inferred that the groundwater in this area is rich in iron content and also the salt content of the groundwater is above the permissible limit. The total dissolved solids (TDS) of the borewell located in the nearby burial ground was tested and found to be 6700 mg/lt (above the desirable limit of 500 mg/lt for domestic consumption). The TDS in shallow borewells of 9m depth is measured and found to be 2000 mg/lt. The depth to water level at the time of study is at 3m below ground level. As the groundwater is inferior in quality, the community feels that renovation of the water body would help in meeting their daily washing demand. Renovating the water body and converting it into a groundwater recharge system will be usefull is improving the quality of groundwater tapped in the area.

One of the major advantage of this pond is that it is not polluted neither by solid waste dumping nor domestic liquid waste diversion 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. The catchment area is in the process of getting urbanized now and hence immediate intervention would protect the water body from liquid waste getting diverted from the urbanized catchment.
The storm water diversion structure (refer picture above) should be constructed properly with proper levels maintained in the inlet and outlets. Hume pipes to be provided in the inlet (picture on the right) and outlets after considering their invert levels. Shallow recharge well of 1.8m in diameter and 2m in depth would suffice the recharge requirement. Based on the Total Station Survey output, it is inferred that the total area of the pond is 4298.75 sq.m and the total length of the bund is 268.71 m. The average depth of the pond is about 2.5 m.

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 3972.9 cu.m Based on this estimate, there will be water available in the pond for almost 121 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 2,636.17 cu.m; the total groundwater recharge will be 1,832.81 cu.m. The estimate was made in an excess rainfall year to see the inflow and outflow status. The actual volume stored in the tank after losses due to evaporation and recharge 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 6048.50 cu.m; the total groundwater recharge is 2080.3 cu.m.

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 desilted and deepened by about 1m.
• The bund can strengthened by providing the desilted material; 
• The pond can be provided with revetment and steps. 
• Provision of a pathway all around the pond to a width of  2m and properly fenced. 
• Stormwater diversion from the storm water drain to be provided through a hume pipe of 300mm diameter after checking its invert level with the inlet.
• A recharge well of 1.8m in diameter to a depth of 3m can be provided in the pond to facilitate groundwater recharge.
