SURAT: India's first district cooperative bank built on the green concept

 SURAT: India's first district cooperative bank built on the green concept will be inaugurated in the diamond city by Chief Minister Vijay Rupani on Friday
Established in 1909, the 109-year-old Surat district cooperative bank  has become the first among the 370 district banks in India and 18 district banks in Gujarat for constructing its new headquarter in the diamond city’s Majura Gate on the green building concept. Constructed on 45,000 square feet, the bank took just 15 months for completition at the cost of Rs 34 crore.

The terrace of the district bank is installed with rooftop solar plant for generating 36 kilowatts of electricity for its in-house needs. The solar panels have been so designed that the electricity requirements would be met even during the monsoon season.

The five-storey bank building has green patches for gardening at each of the floors. The entry of the building has a green landscape with lush garden for providing a different feeling to the customers visiting the bank. Each floor has the facility of toilets and reception, mineral RO plants for clean drinking water etc.
