Groundwater Recharge in Drought Areas of Chitradurga District

Published on Sep 03, 2020


1. From last 50 years, it is observed that the rainfall in the area is decreasing and very uneven from year to year.

2. Due to large consumption of ground water in the area, the ground water table is depleting down.

3. It is also observed from meteorological data that out of 5 years the area receives an average rainfall above 600mm once in a year and in 3 years an average rainfall less than 450mm.

4. To overcome the drought conditions there is no water source in the form of rivers. Hence, it became necessary to recharge the ground water when the area receives more rainfall.

5. The recharged water increases the ground water table, which makes the bores and wells alive even during drought or less rainfall years.

6. Villages selected are Mallappanahalli, Vaddikere, Kalavibagi, Kottige, Gollaryhalli, Harthikote, Giddaobanahalli, Yaradakatte, Salbommanahalli.

1. The main objective of ground water recharge is to store excess water in underground aquifers during times of surplus that can be recovered during periods of water scarcity.

2. To identify the dead wells, bores, ponds and tanks in the area, which can be recharged.

3. To identify the sources of water available to recharge ground water during excess or normal rains.

4. To design suitable structures where water can be recharged economically and efficiently.

5. To educate the people to grow crops whose delta is less during less rainfall years.


1. Data of existing tanks, wells, bore wells is collected from actual survey in the villages.

2. Source of water will be studied and analysed.

3. Rainfall data of area will be collected for about past 50 years from meteorological department.

4. Topographic maps and other data will be collected from the relevant government bodies.

5. Agriculture, horticulture data crops grown will be surveyed.

6. Study of soil strata for permeability and other characteristics.

7. Different thematic maps will be prepared using GIS technology.

8. Design of suitable structures like filtration tank, Retaining walls and recharge pits will be carried out suitably.

9. Probable cost of recharging will be estimated.

Scope For Future Work :

1. Ground water improvement for the surrounding villages

2. Other methods of recharging can be adopted

3. Economical in all aspects due to easily available of materials


1. Suitable method of recharging like designing filters.

2. Increase in the ground water table.

3. Economical and efficient methods of using ground water sources.

4. Suitable methods of design for increasing ground water can be adopted in all such areas where annual rainfall is less.

5. Economical use of water.

6. Suitable selection of crops like Maize, Ragi, Wheat, Cotton, Onion, Groundnuts etc.
