Mexican sewer diver Julio Cu Camara, 52, is lowered down in a cage during a dive at the city's drainage system plant in Mexico City March 21, 2013. Cu Camara's job involves diving in the city's sewage system to clear blockages and repair infrastructure, on an average of four times a month, for about 30 minutes to six hours depending on the amount of work needed. Cu Camara, who started working as a sewer diver 30 years ago, uses a diving suit and helmet that weigh more than 40 kg to protect him during his dives. During his working experience, he has found dead humans, horses, weapons and car parts among other things. Mexico City has a drainage system which measures more than 7,456 miles (12,014 km) long.

Flushers Tim Henderson (L) and Stan Cheeseman pose for a photograph with land surveyor Neil Lloyd (R) in the Thames Water Fleet sewer, a Victorian sewer system designed by Joseph Bazalgette, beneath the streets of London March 13, 2013. After heavy rainfall, raw sewage gushes into the River Thames from a network of dank sewers beneath the streets of London. A Victorian-era problem that has never been fixed, the cobweb-laced tunnels just metres from a new railway station at Blackfriars underscore Britain's infrastructure backlog. The need for a new "super sewer" for Europe's financial capital was identified as far back as 1989 but privatised utility Thames Water, lacked government funding and had more pressing priorities such as cleaner drinking water.

Children fill their jerry can with water in a slum area of the Akhdam community in Sanaa October 24, 2012. Yemeni Akhdam, or servants, are similar to hereditary castes, but are distinguished by their African features and the menial jobs they perform. Widespread prejudice places the Akhdam at the bottom of Yemen's social ladder. Asked about the origins of the Akhdam, Yemenis say they are descendants of Ethiopians who crossed the Red Sea to conquer Yemen before the arrival of Islam some 1,400 years ago - making them outsiders in their own country. Most live in slum areas in the outskirts of the capital Sanaa and other main cities. They reside in small huts haphazardly built of wood and cloth, without basic services such as running water, electricity and sewage networks. REUTERS/Khaled Abdullah (YEMEN - Tags: SOCIETY POVERTY)
