The Origin

During the flood seasons of years 2001 ~ 2005, a series of catastrophic typhoons made landfalls on Taiwan island which each caused severe landslide and mudflow disasters. As a result, tremendous volumes of sands and silts were transported to and deposited in the Shimen Reservoir by streams. Therefore, the water in the reservoir and its upper stream reaches were highly turbid such that the turbidity of raw water in the reservoir drastically rose to over tens of thousands units. Moreover, the very slow settling rates of silts and fine sands in the reservoir led to the severe raw water turbidity to continue for several days without any significant attenuation, which far exceeded the treatment capacities of local water purification plants. Such events aggravated degradation of the functions of these plants, and even compelled the plants to close their operations. Eventually, the concerned water supply to various districts was stopped or carried out on the basis of sub-district by sub-district. Especially in the event of Typhoon Aere that made landfall on Taiwan in 2004, the Taoyuan area suffered from serious water supply deficit for as long as 18 days. The adverse situation resulted in the inconvenience of local people’s livings and the impact on the potential investors’ interest in developing local industries. For solving the water deficit dilemma in the Taoyuan area, the WRA formulated the first phase (Years 2006 ~ 2008) implementation plan of this Shimen Reservoir and its Catchment Management Project (the project). The plan aims to facilitate the preparation of related budgets specifically earmarked and to ensure the implementation progress of the project in good order. Its contents have been worked out in line with the “Special Act Governing the Management of Shimen Reservoir and its Catchment Area” (the Act), which was passed by the Legislative Yuan on January 13, 2006.
