Patna Metro Construction Goes Green with Top Soil Conservation Efforts

17/02/2023

PATNA ( Metro Rail News ): The construction of the city’s new metro system is taking place with a focus on topsoil conservation. Delhi Metro Rail Corporation Ltd. (DMRC)understands the importance of preserving the fertile top layer of soil, which is essential for growing crops, plants, and trees. It is also a finite resource that can take hundreds of years to form but can be easily lost or damaged due to construction and development activities.

DMRC is taking a responsible and sustainable approach to the construction process by
implementing measures to minimize the impact on topsoil and promote its conservation. The topsoil is being carefully removed and stored for future use in parks, green spaces, and other landscaping projects within the city. Fertile topsoil is stripped to a depth of 20cm from the areas to be used for construction, and it is then stockpiled to a maximum height of 40cm in designated areas, covered or stabilized with temporary seeding for erosion prevention and then maybe reapplied to the site during the plantation of the proposed vegetation. It is also in line with the objectives of the Soil Conservation Act, which aims to promote sustainable land use practices and prevent soil degradation.

Saving trees during metro construction is another key aspect of DMRC’s commitment to
environmental responsibility and sustainability. During construction, it is important to
minimize the impact on existing trees and to replant new trees where possible. To achieve this, DMRC has implemented several measures, such as conducting a tree survey to identify and map the location of all the trees on the construction site, protecting them by installing barriers and providing appropriate care or translocating them someplace safe on need basis.

The DMRC is committed to ensuring that Patna Metro Project does not cause undue harm to the city’s tree population and is taking steps to ensure that the new metro facility enhances the city’s natural beauty and greenery.

Innovative Dust Suppression Technology Employed for Patna Metro Construction

PATNA (Metro Rail News): The Delhi Metro Rail Corporation Ltd. (DMRC) has implemented advanced mist spray dust suppression technology to minimize the impact of dust pollution during the construction of the new metro line in Patna. This technology involves the use of specialized equipment to produce fine particles of water that bind with the dust particles, preventing them from becoming airborne. By strategically placing the mist spray equipment on-site, the entire construction area is covered, making it an effective and eco-friendly solution for controlling dust pollution.

Patna’s air quality has been a growing concern in recent years, with the Air Quality Index (AQI) frequently exceeding safe limits set by the World Health Organization. However, the use of mist spray dust suppression technology during the construction of the Patna Metro has the potential to significantly control the AQI in the city. It is an ideal solution for cities like Patna where air pollution is a serious concern and will solve the concerns of local residents regarding dust pollution around construction sites.

The effectiveness of mist spray technology in controlling dust pollution, even in the harshest conditions, has been proven. It not only keeps the surrounding area clean but also reduces the risk of respiratory problems for workers and nearby residents. DMRC ensures the implementation of environmental best practices for controlling emissions or minimizing the impact of construction activities on the environment, as required by the Air (Prevention and Control of Pollution) Act, 1981.

The construction of the Patna Metro is expected to be completed by 2026 and will provide much-needed transportation options for residents in the area. With the use of mist spray dust suppression technology, residents can be assured that the project will be carried out with utmost care for the environment and their health.

DELHI (Metro Rail News): The forthcoming Regional Rapid Transit system (RRTS) corridor in Delhi is likely to reduce the travel time from different locations in the NCR and other adjacent places like Haryana and Rajasthan to National Capital. Passengers will be able to travel from Ghaziabad to Haryana in just 45-50 minutes through Delhi-Panipat Corridor, and Delhi-Gurgaon- Alwar RRTS corridor will help travellers to commute from Delhi to Neemaran in around 70-75 minutes.

The Central government had approved the Delhi-Panipat RRTS corridor.

However, they have got the approval of the Haryana and Rajasthan governments.

The Delhi-Panipat corridor, which is 103 km long, will connect Delhi with Sonipat and Panipat in Haryana. It will also link Murthal, Ganaur, Samalkha, and Panipat to Delhi with high-speed rails. There will be 17 stations on this line. Delhi will have six stations ( Sarai Kale Khan, Indraprastha, Kashmiri Gate, Burari, Alipur and Mukarba Chawk ). With the help of this project, people will be able to reach Murthal in about 40-50 minutes and to reach Panipat from Delhi, it will take around 65 minutes.

The Delhi-Gurgaon-Alwar Corridor will be developed in three phases. In phase one, the 107-km-long SNB Urban Complex (Shahjahanpur-Neemarana-Behror) will be constructed, which will link Gurgaon, Manesar, Panchgaon, and Rewari. Commuters will be able to travel to Neemarana from Delhi in just 70-75 minutes.
