Description of Event:
Smt. Rukmini Shyama Raju Club for Social Service, School of Civil Engineering organized a cleaning programme at puttenahalli lake near Yelahanka. The students of school of Civil Engineering joined our hands with the team of IASE. The students of social service club had actively participated in cleaning of the lake by removing the weeds from the lake.
Puttenahalli lake is a 10-hectare water body, near Yelahanka, 14km North of Bangalore. This lake has been listed in the said LDA and is a habitat of birds. At present it is just a moss filled pit with stagnated water which is emiting four smell. It is observed that it is a home to many rare species of birds.
The day began with preparation of boat with drums, which was attached to the bamboo sticks in order to go inside the lake. Some of the workers went inside the lake with the help of the boat. A big rope provided to us was used to remove the weeds from lake to the land. The worker inside the lake used to put the rope around the weeds and rest of the students use to pull the weeds with the help of rope and dump on the other side.
The weeds were removed and spread on the land, which was left to dry and decompose. These weeds were further can be manure and can be used in place of fertilizers to grow the plants on the side of the lake as this lake is a home for bird.
Purpose of cleaning programme:
• Puttena halli Lake is stinking & whenever people pass through they experience foul smell. This is not done the cleaning for several years.
• This lake could be converted to minimize smell nuisance so that the inhabitant of nearby residential area can use it for their relaxation.
• This place was once a bird sanctuary and it may be possible to regain the glory.
• We must keep the water bodies clean as the water is very precious and scarce. It can recharge the ground leading to potable water by bore wells for nearby residences.
Outcomes of the programme:
• Puttena hally Lake got cleaned and week load on the lake was reduced.
• The foul smell due to stagnant water is minimised.
• We may hope to see the chirping of birds in future.
• We can get the manure by decomposition of the weed which we have removed from lake. This manure can be used for plants & trees around the lake.
Concluding remarks:
After the programme by the School of Civil Engineering, budding engineers of the school got the awareness & importance of cleaning the lakes. The student actively participated in cleaning of the lake with some innovative ideas for making raft & methods to remove the weeds of lake.
