Hong Kong's third-world water management system in urgent need of repair
Asit K. Biswas says Hong Kong's poor management of its water resources, from the waste in usage to its inept policy decisions, does not befit a city of its wealth and development

Over the past several decades, Hong Kong's water supply and wastewater management practices have been on an unsustainable path. Poor planning, absence of sustained interest from its top policymakers, an uninformed public, lack of regular media scrutiny and a series of poor policy interventions have ensured that, today, it lags behind nearly all cities of similar levels of economic development in its management of water.
Hong Kong is a net water importer. Currently, 70-80 per cent is imported from Guangdong's Dongjiang through multiple agreements. The Audit Commission reported in 1999 that the planners had so badly overestimated city water requirements in the 1989 agreement that some 716 million cubic metres of water literally went down the drain, which cost taxpayers, between 1994 and 1998, HK$1.7 billion.
Even after this sad performance, the next agreement was even worse. The requirement was again another overestimate. Consequently, between 2006 and 2012, the city had to pay for seven years of water imports but in reality used only about six years of water. This over-estimation cost the taxpayers another HK$2.8 billion.
As an adviser to 19 governments, I am not aware of a single city anywhere in the world which has consistently overestimated water requirements so badly for over two decades.
Not only has overestimation been a serious problem, but also no serious policy measures were taken to manage domestic and industrial water demands. At present, average water use in Hong Kong is about 220 litres per capita per day, a figure that is higher than in 2003. This is bad management since in nearly all similar cities of the world, the usage trends are generally declining because of better management practices and increasing awareness of the people that water is a scarce resource.
Accordingly, inhabitants of cities like Hamburg and Barcelona use about half that of an average Hongkonger. In Singapore, per capita water use has steadily come down in recent decades. It is now 152 litres per capita per day, which is still on the high side. An average Hongkonger uses 45 per cent more.
One of the reasons for this very high usage is because water and wastewater provisioning has been subsidised at higher levels with each passing year. The water tariff has remained the same since 1995, but costs of services have gone up steadily. This has resulted in some ridiculous situations, like the city providing private bottled water companies with highly subsidised water, which at the retail level is being sold at over 1,000 times the cost of city water.
