Question

How does the water in rain fed tank get its colour?

Answer 1

the colour of the water of the rainfed tanks varies with the nature of the earth of the catchment area

Answer 2

the water in the fed tank helps in the rusting process of the tanks. The fed tanks are usually made up of iron and are not coated so often. as a result a thick brownish iron oxide gets layered in the tank having a chemical formula of Fe2O3.XH2O .
