1.1.1.WATER RESOURCES The main characteristics of Taiwan’s rivers are as follows: •21 major rivers, 29 secondary rivers and 79 minor rivers; •Relatively small drainage area, only nine rivers exceed 100km2; •Relatively short length, only six rivers exceed 100km; •Relatively steep slope, upstream reaches exceed l/100, downstream reaches I/200-l/500, only five rivers have slope milder than l/1000; •Poor watershed geological conditions; most watersheds are sandstone and shale and easy-tocollapse. Sediment concentrations are huge. There are also special geological structures such as mudstone and conglomerate which can easily become mudflow; •Concentrated rainfall, rapid flows, poor flow conditions, uneven time distribution of flows and rapid rise of flow peak.
1.1.2.WATER USE Agriculture is the major water user in Taiwan, accounting for 78 per cent of all use. The construction of a major canal from south to north is envisaged to alleviate water scarcity in the north. Seasonal variations of water availability, causing floods and droughts, are a major problem. Industrial pollution affects many rivers. Natural contamination of groundwater with arsenic and fluoride affects the drinking water supply of about 4 per cent of the population. Water resources management is fragmented among various agencies and levels of government.
1.2.WATER QUALITY, ECOSYSTEMS AND HUMAN HEALTH The following factors influence water quality in the country: •The population density of Taiwan is the second highest in the world. Domestic sewage is the major source of water pollution for many Taiwanese urban rivers. •Wastewater from the swine industry used to be a major water pollution source. Domestic pig farms are gradually becoming smaller after joining the World Trade Organization, but there are still about 7 million pigs being raised in Taiwan. •Over the last three decades Taiwan has begun to develop itself into a big international trading economy. There are nearly 11,000 factories in the country, whose manufacturing processes usually produce wastewater containing various contaminants.
2. GOVERNANCE ASPECTS 2.1.WATER INSTITUTIONS On 16 December 1972, President Chiang Ching-kuo, making an important urban development policy statement, gave the following instructions: “In order develop a public water supply system island-wide, a water corporation must be established immediately at the provincial level. At the same time, we must speed up the implementation of long-term plans for the development of water supply in order to concentrate human and financial resources, increase investment benefits and reduce operational cost.” In accordance with these instructions, on 1 April 1973, the Taiwan provincial government set up a preparatory office for the Taiwan Water Corporation, which now draws up plans for unified management and long-term development.
