Rainwater Harvesting Tanks

FAQ: What tank would be best for rainwater harvesting at a camping site?

The customer needed a rainwater harvesting tank for camping site that was located on a mountain top. Collapsible tanks were offered as a solution for their low costs and easy transportation.

Question: I want to build a campsite on top of a 1000ft mountain that is hard to climb. The area has a rainfall of about 700 mm per year. I want a system to catch rain water on top of the mountain to provide campers with water for washing. As everything has to be physically carried up the mountain, I'm thinking of a portable water tank and a way to catch the water.

The rainy season is from November to March and I need to store water from April to November. I think I'll need to store a total of 10,000 liters. If you have a solution, where can I buy if I live in Namibia?
