2. ABSTRACT
• Water samples are collected from randomly selected 20 different sampling
sites for analysing physicochemical parameters.
• The work evaluated is the Ground Water Quality and Quantity analysis of
Devanahalli area, Bangalore dist., Karnataka.
• Here in this study, it is analysed the physiochemical parameters like pH,
Turbidity, Total dissolved solids, Alkalinity, Total hardness, Calcium,
Magnesium, Chloride, Sulphate, potassium, phosphate, Faceal coliforms.
Spatial Analysis for all the parameters is done.
• Quantity analysis Aquifer zone identification, Aquifer zone mapping,
preparation of Thematic maps, Overlay analysis, calculation of aquifer zone
Creation.

3. INTRODUCTION
• Water is one of the most basic needs for all life on Earth. It occupies the vast bulk of our planet's
space, accounting for roughly 71 percent of the planet's total surface area.
• The study of the distribution, availability, consumption, and flow of ground water is known as
hydrology.
• There are three major types of surface water. Permanent (perennial) surface waters are present year-
round, and includes lakes, rivers, and wetlands (marshes and swamps).
• Semi-permanent (ephemeral) surface water refers to bodies of water that are only present at certain
times of the year including seasonally dry channels such as creeks, lagoons, and waterholes.
• Man-made surface water is water that can be continued by infrastructures that humans have
assembled. This would be dammed artificial lakes, canals and artificial ponds (e.g., garden ponds)
or swamps.
• Devanahalli was originally part of Gang wadi and was later ruled by the Rashatrakutas, Nolambas,
Pallavas, Cholas, Hoysalas, and Vijayanagara monarchs.
• Devanahalli's recent history stretches back to the 15th century, when a family of refugees escaping
Conjeevaram (modern-day Kanchi) settled at Ramaswami betta, east of the Nandi Hills.

4. OBJECTIVES OF THE
PROJECT
•Qualitative analysis of water Samples to understand
the physicochemical condition of water in the taluk.
•Seasonal variation quality and quantity of ground
and Surface water.
•Rejuvenation of surface water and Aquifers.
•Implementation of integrated water management.

5. METHODOLOGY

6. Under water quality tests, we have
1. Physical parameters : Color ,Odor, Taste , Turbidity, Electrical
conductivity
2. Chemical parameters : pH , Dissolved oxygen, Total hardness,
Alkalinity, Total dissolved solids, Total suspended solids,
Fluorides, Nitrates, Chlorides, Sulphates
3. Biological parameters : E COLI (M.P.N: - Most Probable
Number)

8. RESULTS

12. TEST RESULTS

13. ADVANTAGES
1. Physicochemical analysis helps the improvement of the water quality of
the area.
2. Aquifer zone mapping helps to identify the water zones present in the
Borewell.
3. Thematic maps explain Exploratory spatial analysis, synthesizing spatial
data by revealing patterns and relationship and data presentation.

14. DISADVANTAGES
1. Improper maintenance of the physicochemical analysis process.
2. Aquifer depletion from over pumping, the amount of local
precipitation, water tanks can be very hard to clean.
3. A thematic map that are composed of a special purpose and a statical
map that is based on the spatial variation, does not present exact
values, it can be difficult to distinguish between distinct shades.

15. ACHIEVEMENTS
1. The project is sponsored by the Water Institute, Department of Civil
Engineering, UVCE, Bangalore University Bengaluru.
2. The project is selected for project exhibition.
3. Publish the Journal paper.

16. SOCIAL IMPACT
1. This can increase the water potential in the area, which is helpful for
the sustainable development of Groundwater.
2. Enriches the availability of the water.
3. Water management in the area

17. • Maximum areas which can hold a Moderate quantity of water and floodplain areas are the good potential zones of GW.
Terrain belongs to the hard rock runoff is more and infiltration is very less hence tanks constructed across the stream to
store the water.
• Northern part of the terrain has very little groundwater as it contains the high slope and hilly terrain. Southern part of
Devanahalli Taluk is having good potential zones of groundwater as it has more tanks and 7th order drainages.
• Slope and aspect of the area reveals that the southern part of Devanahalli Taluk has a gentle slope compared with the
northern part of the study area. The East and West part of Devanahalli Taluk have moderate groundwater potential
zones, as they have moderate slopes.
• International airport is located at the southern part of the study area which needs more quantity of water.
• Rainwater harvesting is the only solution to recharge the aquifer, presently which is getting depleted due to the
overexploitation of groundwater.
• Output is validated with the Borehole depth data which reveals that, borewell depth in few cases mainly depends on the
Lineament and apart from this water is available at the Greater Depth around 1200ft.
• From the meteorological data it reveals that the source of Groundwater in Rainfall if failure in the seasonal rainfall hits
directly the storage of GW intern results in the draught.
• Decrease in the water levels of the tanks are due to the highest evaporation rate in the study area in the peak summer.
