AREA: 5260.918000000001 Sq.mtrs    ZONE: 2    DIVISION: 16

This pond is in Division 16 of Zone -2, Manali and is located on the Kanniamman Pettai - Kadapakkam Road (off Andarkuppam  Redhills Road). It is located to the East of the road. It is bounded by road in all three directions and by settlements in South. The pond is located at North Latitude 13 11'43.40" and East Longitude 80 15'19.01"

The pond is rectangular in shape. There is water in the pond at the time of survey and is in use by the local community for bathing and washing purpose. . The pond is provided with retaining wall all around, with steps in one side of the pond ((North Eastern side). The agriculture fields located to the west of the pond is the major catchment to the pond.

The area around the pond is urbanized. There is a culvert provided on the road to divert the surface run off and an inlet provision was made in the pond to catch the run off. Weep holes have been provided on all side of the revetment wall of the pond to harness the surface run off all around. Based on the interaction with the local community, it is inferred that the pond used to hold water for about 9-10 months. In the past, the pond water was used for even cooking purpose due to its good quality. At present it is used for mainly for washing purpose. There is no revetment provided in this pond. As such there is no solid or liquid waste (sewage) diversion into the pond but for minor amounts of sullage diversion that can be prevented by providing soak pits at the source. The pond as such is in good shape in terms of water spread, free from encroachment / pollution. Minor encroachments observed along the bund of the pond. 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. Shallow open dugwells and filter point borewells are the common groundwater extraction structures in the area used for domestic and agriculture purposes. The groundwater is reported to be moderate in quality. Rejuvenating the pond will help to improve and sustain the groundwater resources in this area. The storm water drain constructed along the road can be checked and diverted to the pond provided there is no pollution in the storm water drain as such.

The actual volume stored in the tank during 1987  during 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 13,367.63 cu.m Based on this estimate, there will be water available in the pond for almost 118 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 7,886.38 cu.m; the total groundwater recharge will be 5,640.54 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 136 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 rainfall year is estimated at 16,550.51 cu.m; the total groundwater recharge is 6260 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.

• As there is water in the tank, it can be retained as such without any desilting or deepening.       
• The bund need to be trimmed, strengthened;
• Steps can be strengthened.
• Bush clearance all around the pond and provision of a pathway all around the pond to a width of  2m and properly fenced. 
• A diversion from the storm water drain into the pond can be provided.
• A recharge well of 1.2m in diameter to a depth of 3m can be provided in the pond to facilitate groundwater recharge. .
