A team of the Delhi and Noida metro rail corporations on Tuesday made a presentation before the state environment impact assessment authority (SEIAA) in Lucknow to obtain clearances for beginning the 30-km Noida-Greater Noida metro project.
The SEIAA will assess and take a call on environment clearances later.
The 30-km Noida-Greater Noida metro link is expected to be ready in November 2017 and about 50 % of the work has been completed.
The Delhi Metro Rail Corporation (DMRC) and the Noida Metro Rail Corporation (NMRC) are obtaining environment clearance after the NGT order in response to a petition that metro projects should also obtain such clearance.
The team of DMRC and NMRC officials gave a detailed account of the scale of construction and the requirement of land, water and other resources.
As per the detailed project report of the 30-km project, 1,40,00,000 litres of water is required during the construction phase of the project. The project requires 53,622.67 sq m of land for metro stations, 16,000 sq m for substations, 700 sq m for a radio tower, 2,00,000 sq m for a depot and 14,439 sq m for a running track.
Environmentalist Vikrant Tongad, who had filed the petition in the NGT in April, alleged that many metro project details that the DMRC provided to the SEIAA are incorrect.
“The DMRC informed the state environment authority that it has parking facility only at six stations. But, they have parking facility proposed at all 21 metro stations that are being built on this link. Also, the DMRC is using a green land for casting yard and not taking enough steps to conserve rainwater,” Tongad said in his complaint.
The DMRC has not made provisions for rainwater conservation at its six metro stations between Noida City Centre and Mayur Vihar-I in Delhi, Tongad said.
Officials of the DMRC and NMRC, however, denied the allegations made in Tongad’s complaint.
“We will reply to every objection raised in the complaint. The casting yard is temporary and we will develop a park on the same land once our work gets completed. The Noida authority has provided us land for parking facility at six metro stations so far. We have told the same to the environment authority. We have laid down provisions for rainwater conservation at all six metro stations,” Santosh Yadav, managing director of the NMRC, said.
Gauhar Mahmood of Jamia Milia University’s engineering department said that the NCR cities get waterlogged even after a brief spell of rain because steps are not taken for rainwater conservation.
“Be it metro or any other big project, we will have to ensure that rainwater is used for recharging groundwater. Else, we will face environmental repercussions,” Mahmood said.
Pramit Garg, DMRC project director for the Noida-Greater Noida project, said, “We are conserving rainwater at the current six metro stations in Noida. Similarly, we will lay provisions to save rainwater at 21 stations coming up on the 30-km under construction Noida-Greater Noida metro link.”
NMRC on Tuesday started construction of five 2.9 metres X 17.5 metres precast pier cap. The 160 tonne pier cap is a slab on which Metro track and platform rests. Made using French technique, pier cap of this size is being made for the first time in India, says DMRC officials. Total 105 pier caps will be built for Noida-Greater Noida Metro link.
