First, welcome to permies!
India is a huge country with a robust manufacturing sector--so all the components are available in the country--but whether they are available in your local area is a question I can't answer. A steel drum and rockwool are the most essential components, and the rest can be made out of a variety of materials. Have a hunt around your area to see if you can find or order those. If so, I'd go ahead with the project. Best of luck!
