The best material for harvesting water is corrugated iron sheets. I have heard that clay tiles need at least one or 2 rainy seasons before the water can be harvested but even then it may not be 100% safe for drinking.
I beg to differ, natural clay tiles are safer in the long run, the worst u can get is some clay sediment in the early days, and after all, its natural stuff that can't harm you.
