In the recent times, even though the general awareness about environment has grown, the problems associated with environmental deterioration are ever increasing. The destruction of environment is going on at alarming pace. The efforts to solve these problems are not bearing desired fruits. The main reasons for these failures are increasing population and fast changing life styles. This has resulted in over exploitation of limited natural resources. Added to these, we do not have accurate and scientific statistics and information about the current status of our environment. The genuine efforts to create awareness about these issues in general public are not adequate. General public seem to be callous and indifferent giving the lame excuse that “solving environmental problems is the sole responsibility of the government”.
Today, we are all facing acute shortage of pure water, and this problem is only increasing day by day. Till recently, naturally available water from sources such as tanks, lakes, streams, open wells and bore wells could be used without much treatment. However, many of these water sources have been polluted beyond repair. 

Today, the city of Bangalore needs 12 TMC of water per year (on an average of 1 TMC per month). To give a comparison, the total capacity of KR Sagar reservoir is 32 TMC. Currently, the water supply needs of Bangalore City are met mostly by Cauvery River, balance by other smaller water sources. Out of this water consumed, the city generates about 7 to 8 TMC of waste water, which on its way, pollutes many water sources such as rivers, wells, tanks, streams, reservoirs, etc.

In the year 1933, with the sole purpose of supplying water to Bangalore city, the then Maharaja of Mysore, His Excellency Shri Nalvadi Krishnaraja Wodeyar, through Dewan Sir M. Vishweshwaraiah, planned and constructed a dam in Tippagondanahalli (TG Halli) to create a reservoir. The dam is constructed across the Arkavathi River (originating from Nandi hills) and Kumudvathi River (originating from Shivagange hills). The reservoir (which is at a height of 2575 ft. from the Mean Sea Level) has about 532 sq. kms of catchment area and has a capacity to hold about 3.3 TMC of water.
This reservoir was supplying water to the entire Bangalore city till 1970. However, problems such as reduced rain fall, depletion of greenery around the catchment area, increased flow of silt and pollution to the reservoir and encroachment are pushing the TG Halli reservoir to the brink of extinction. Even today TG Halli reservoir is supplying water to various parts of Bangalore such as Rajajinagar, Basaveshwaranagar, Malleshwaram, Mahalakshmi Layout, Vijayanagar, Kamakshipalya, Sunkadakatte, Peenya, etc.

The local villagers and agriculturists share their experience that in the past small streams around the TG Halli reservoir area were full of water, even after the rainy season. They opine that the main reason for this was the abundant greenery in and around the catchment area. However, now the streams are dry within hours of rain fall. The indiscriminate felling of trees has resulted in erosion of soil and depletion of fertile top layer. Soil erosion has also resulted in siltation of the reservoir area, thus reducing its holding capacity. Encroachment of the government land in and around the catchment area has also added to the destruction of bio-diversity. The lands have become dry and arid. Unplanned housing and industrial developmental activities around TG Halli area is slowly polluting the land and the reservoir itself.

It is the social responsibility and sacred duty of every Bangalorean to save this reservoir, which had given us water all along, and bring it back to its past glory. We all should make this purpose a part of our life style. Even a small effort put in this direction would help in reducing the pressure on the eco-system of TG Halli reservoir. Constant research, creating awareness and planting trees could be some of the efforts in this direction. It has become imperative that large groups should work as a team to achieve these objectives. Planting seedlings and growing trees in this catchment area could be a wonderful effort in preserving environment.
Currently, in Bangalore city alone, about 90,000 births, about 20,000 new house constructions, about 10,000 marriages and about 35,000 deaths take place every year. In addition, number of other functions such as birthdays, anniversaries, etc., that are celebrated are innumerable. In total, about 2.5 to 3 lakh functions are celebrated annually in Bangalore city alone and they are only growing year after year. Most of these functions are celebrated in very grand ways incurring significant expenses.
Through our project, it is proposed to offer opportunities to the citizens to celebrate / observe any of the occasions and make it a memorable one by planting seedlings and growing trees.

We sincerely hope that our efforts will inspire many others to take up similar projects in their respective areas to improve the environment and make our planet a better place for the future generations.
