Water storage ...

.... built by humanity.

There has been little to no rain for around 6 months in the rural areas of southern Spain and water storage, preservation and distribution is a major concern. These are traditional water storage tanks one will find walking along the rural trails, on the farms and in small villages. They can be of all sizes -- these are around 4 metres tall -- and are used primarily for irrigation and watering animals.

In the extra, a rustic method of providing water for goats in scrubby, arid land where there is no other water source. This is simple, yet effective, human resourcefulness, with a tank on wheels, a pipe and a bath tub.
