This is what it costs to install a water pipe in Manila. Equivalent to more than three years’ worth of vended water, it is a heavy investment for people living on a day-to-day subsistence basis.
Rapid population growth in urban Asian cities have placed severe pressure on water companies. Estimates reveal non-revenue water losses of about 50-65%, due to unauthorised consumption, inacuurate metering or pipe leakages.
How do they get water?
In urban Philippines, only 60% of the population have piped water. Water companies are reluctant to supply to slums, because the act of doing so may “legalise” the informal settlements.
Those who cannot afford piped water often turn to small-scale private providers. In 2003, they supplied water to 44% of the population in Jakarta, at a much higher cost. Drinking

Rivers, lakes and wells represent a key source of water in Southeast Asia. However, they are threatened by pollution due to a lack of wastewater treatment and massive leakages into the water table.

Five drums of water, which can last a person for 20 days, can cost up to US$3 in Manila. The same amount of water from a pipe would cost about US$0.20. There is little regulation and no guarantee of the water quality.

the cost of piped water across the region
Cities in Southeast Asia use different models to price water for household consumption. The state of Sabah in Malaysia adopts a flat rate scheme, while cities like Singapore, Manila, Phnom Penh, Vientiane and Penang price their water according to blocks. Debates on sustainable cost recovery and marginal cost pricing are ongoing and it is unclear which system is superior or better for the poor in Asia.

About 40% of the population in urban Cambodia are forced to practice open defaecation due to lack of access to basic sanitation.
