A man pours excess water on to the road after filling up his barrel (R) with water from a spout near the construction site of a building on Augusta street, in Sao Paulo February 3, 2015. Builders opened a water well by drilling into one of the numerous rivers running underneath the city of Sao Paulo, according to local media. Residents and small businesses are taking advantage of the water from the spout as Sao Paulo, Brazil's largest city, has nearly run out of water and whole country faces power rationing as the worst drought in more than 80 years dries up hydroelectic reservoirs.
