How to change the chennai city green

  1. 1. As an Engineer, How can we turn the Chennai city green???? By, JINAL JOLLY, 20074614, B.E AIE, CEG, Anna University.
  2. 2. Current Environmental problems in Chennai??? 1. Air Pollution and dust in roads. 2. Lack of trees. 3. Unclean cooum. 4. No space for waste deposition. 5. Water logging during rainy season.
  3. 3. As an Engineer, how can we resolve these? 1. Sprinklers in traffic signals: Sprinkling of water subsides dust. • Apart from using Water sprinklers for irrigation, it can be attached in the traffic signal posts, in which it can sprinkle water in a split of second when the signal is turned red. • This synchronisation of sprinkling water according to the timing of signal is electronically tuned.
  4. 4. 2. Narrow jet water sprayers in middle of road. • In the road seperators, tall water sprayers are attached. • These sprayers drizzles very less water such that the air get moist, while the pedestrians and vehicles are not wetted. • Sea water can be used in these sprinklers.
  5. 5. 3. Cooum reclamation • The project is on process. • 10 years for completion&1200 Cr budget. • But maintainance is more important than reclamation. • For this, secret cameras can be fitted along the banks to catch those who dump wastes on the river. • Dumping should be considered as illegal and they must be punished. • Political support is required for this.
  6. 6. 4. Find land for planting trees • The space under Kathipara fly over.( Shallow root trees) • Vast land unused in Kilpauk cemetery which is a very fertile land. • The bank along the Cooum river( Only after 10 years) • Instead of shrubs, plant tall narrow trees in the road seperators. • More parks in waste lands
  7. 7. 5. Creation of artificial infiltration ponds • Rainwater is allowed to stagnate in big artificial ponds and allowed to infiltrate thereby recharging groundwater. • This should be made compulsory in every School & College in Chennai, since open free spaces are always available there. • Political support is again required for this to achieve.
  8. 8. 6. Create huge swimming pools • Create huge, impermeable and non penetrable pools. • Expose it to the atmosphere during rainy season. • Close fully after rainwater is filled so that the water is not polluted and evaporated. Aerate periodically • Reuse the pure water during summer since rainwater is the purest of all water.
  9. 9. 7. Over head Neel Metal Fanalca. • Huge over head tanks are constructed in the Neel Metal Fanalca deposition area and instead of depositing the wastes on ground, it is deposited on these tanks using cranes and are burnt periodically. • Thus it will reduce the soil pollution thereby allowing water to infiltrate. • The harmful substances which are not supposed to burn are packed in a 100% air tight containers and can be safely deposited under sea.
  10. 10. 8. Parabolic roads. • The roads are designed in a parabolic manner which means higher at the middle and lower at the sides inorder to prevent water logging in roads. • The design should be safe enough to ensure the safety of the vehicles. • The drained water can be directed towards the roadside drainage.
  11. 11. FEASIBILTY??? 1. Economic Feasibilty • These are estimated to be high budget projects and cannot be done privately. • Only source is Tamil Nadu Govt. 2. Social Feasibility • Political support is very much required to put rules and orders. • Common people’s support should be always needed.
  12. 12. SO LETS JOIN OUR HANDS TOGETHER TO CREATE A GREEN CHENNAI………
