Checking waste could bring water to millions in Asia - Study
Millions of people in Asia and the Pacific could have access to clean
water if leaks were plugged and water utility reforms adopted, says a
new study by the Asian Development Bank (ADB).
"While Asia and the Pacific is increasingly facing a major water
crisis, we see unacceptable levels of water being lost through leaks and
inefficiencies," said ADB's Vice President for Knowledge Management and
Sustainable Development, Bindu Lohani, "By cutting the amount of lost
water in half, 150 million people could be supplied with treated water."
ADB estimates that 29 billion cubic meters of water is lost each year
in the region - enough to fill more than 11 million Olympic-sized
swimming pools - causing Asia's water utilities to lose more than $9
billion in revenue each year.
By examining eight of the best-performing water utilities in Asia,
Good Practices in Urban Water Management concludes that a low rate of
unaccounted for water (UFW) is critical for efficient service delivery.
While current UFW levels in the region are as high as 60 percent, an
UFW level of less than 20 percent is a realisable goal. In fact, it
notes that Phnom Penh managed to bring its lost water rate down to just
six percent in 2008.
The study identifies seven universal themes to serve as a model for
replication by water utilities: corporatisation for better
accountability, economic sustainability, unaccounted-for-water
reduction, holistic approach to manage water resources including water
supply and waste water management, staff productivity, collaborative
engagement among government, utilities and society and inclusive
approach to addressing the needs of the urban poor.
Asian water utilities need to show innovation to provide service to
low-income households, the study says, noting that each of the eight
water agencies studied provided some kind of subsidy for obtaining a
water connection and, in deserving cases, for the use of water as well.
Launched recently at the Singapore International Water Week, the
study cites Singapore as one of the models for water management which
other Asian cities can learn from. The country has a low level of lost
water due to leakage, a strong government commitment for water
sustainability, and is pricing water to take in the full costs of
delivery and management. Its
water utility, PUB, is seen as a test bed for innovative
technologies.
The study, which is a collaborative effort between the ADB and the
Institute of Water Policy, Lee Kuan Yew School of Public Policy,
National University of Singapore, provides new insights into urban water
management in the cities of Bangkok, Colombo, Jamshedpur, Kuala Lumpur,
Manila, Phnom Penh, Shenzhen, and Singapore.
