On the eve of Environment Day, MD, HMR Mr.NVS Reddy conducted a brain storming session with the engineers of L&T, HMR and the energy conservation and environmental experts working with the Metro project regarding the strategy of the Metro project to contribute to environmental improvement in Hyderabad city. The experts have informed that Hyderabad Metro will reduce about 3.5 lakh tonnes of CO2 (carbon dioxide) and other pollutants from the atmosphere in the city in a year mainly due to containment of usage of personal vehicles, reduction in consumption of diesel and petrol, etc.
A study conducted by the Central Road Research Institute(CRRI) revealed that Delhi Metro reduced 3 lakh tonnes of vehicular pollutants in 2011 and recovered the whole cost of the Delhi Metro project in 5 years in terms of it’s economic benefits (reduction in fuel consumption, savings in travel time, reduction in pollution levels, etc.).
Usage of regenerative technologies by which the power produced by the braking system of Metro coaches will be reused; efficient utilization of natural light in Metro stations, workshops and other buildings; usage of energy efficient electrical devices and solar energy form part of the Hyderabad Metro strategy to contribute to environmental improvement, which is as under:
- Benchmarking Hyderabad Metro performance against world’s best Metros for environmental improvement.
- Adoption of energy efficient technologies at design stage for optimum benefits.
- Metro stations, workshops and other buildings to be constructed as green buildings with natural ventilation to reduce air-conditioning and lighting requirement.
- Cantilever station design on only central pillars to avoid tunnel effect and lighting requirement.
- Replacement of 20% cement by fly ash in concreting works to absorb the earth polluting fly ash and to reduce cement consumption.
- Saving of about 50,000 litres of water per day by usage of curing compound instead of conventional daily water curing of the concrete pillars, station structures, etc.
- Creation of about 500 water harvesting structures near Metro Rail stations, along Metro corridors and in depots and other buildings.
- Reduction/containment of noise pollution generated by road vehicles through noise containing sophisticated Metro coaches, low vibration trackforms, resilient base plates, suspension systems, erection of noise barriers in sensitive zones, etc.
- Large scale plantation along Metro corridors and in other parts of the city.
Mr.NVS Reddy and L&T Metro Rail MD Mr.VB Gadgil have indicated that they would strive to make the Hyderabad Metro one of the best Metros in the world in terms of energy efficiency and to reduce pollution levels in the city.
