The port sector would require investment worth 550 billion rupees while shipping and inland waterways would need another 450 billion rupees by 2015, he told reporters after a business conference.
India's Planning Commission estimates that the infrastructure sector will require investment of $500 billion between 2007/08 and 2011/12, which is key for the economy to sustain an average 9 percent growth.
"We will require one trillion rupees investment by 2015 (in ports, shipping and inland waterways," Sarma said.
But a cash-strapped government is looking for greater private role in infrastructure building and has been inviting foreign players to pour in more money and bring in their expertise in Asia's third largest economy.
"There is tremendous room for private sector to participate. We have got a lot of response from foreign players for the port sector," Sarma said.
Sarma said cargo handling volume in 12 major ports in India was at 520 million tonnes, while smaller ports contributed another 260 million tonnes during 2007/08. "We are expecting a 12-15 percent growth in 2008/09."
The government aims to double capacity in major ports to 1,000 million tonnes by 2011/12, and raise it to 500 million tonnes for smaller ports, he said.
Raising port capacity and speedy cargo handling is crucial for India to sustain high growth in exports and imports.
India's trade minister said last month exports are expected to grow by more than 20 percent to $155 billion. Imports grew at a faster pace of 30 percent and stood at $211 billion in the first eleven months of 2007/08.
