Residents of Cambodia's capital city used to have little access to safe drinking water; now more than 90 percent of homes have it.
Phnom Penh, Cambodia
Ek Sonn Chan, the general director of the Phnom Penh Water Supply Authority, offers visitors to his office cool water in a crystal glass, covered by a silver lid in the shape of a Cambodian crown.
It is tap water – unboiled.
He drinks from his glass first, after taking off the lid and waiting a moment to let the chlorine smell dissipate. Then he encourages his visitors to do the same.
"I always guarantee to all my guests – if you drink my water and have a problem, I will be responsible," he says. "All my staff drink the water from the tap. My granddaughter is 1 year old and she drinks the water from the tap."
The water in this developing-world capital comes from the river – a river into which floodwaters mix with water from the sewer drain during rainstorms. (The city has no waste-water treatment plant.)
Yet the employees at the city's water authority guarantee it is safe to drink. The water is so good that it passed the test of the Coca-Cola Co., they say.
In 1993, when Mr. Chan took over as director of the water authority in Phnom Penh, Cambodia, the government enterprise wasn't even making enough money to cover its electricity bill or to buy chlorine for purification.
Employees made extra cash by selling illegal connections to the city's water pipes. More than 72 percent of the water supplied into the system was unaccounted for – either lost due to leaks or stolen.
After the end of the brutal Khmer Rouge regime, during which the city had been emptied of its inhabitants, the staff didn't even know where more than half of the pipes in the 174-mile distribution system were. Only a small area close to the city's center had running water, and the pressure was so low that water couldn't even go up to the second floor of buildings.
