Water Intake and Supply System

Last Updated:2019-07-22 Visitors:3235

The water supply system of this bureau is mainly divided into tap water and irrigation water supply systems. The intake and supply systems of tap water include the Shuangxi Creek and the Keelung River (the First Branch of the Taiwan Water Coporation), the Xindian River (Taipei Water Department), the Dahan River (the Second Branch and the Twelfth Branch of the Taiwan Water Coporation), and the Touqian River (the Third Branch of the Taiwan Water Coporation). Their water supply systems are described as follows:

The Shuangxi Creek and the Keelung River belong to the water supply districts of the First Branch of the Taiwan Water Coporation. The water resources mainly rely on the streamflow of the Gongliao weir of the Shuangxi Creek and the Badu Pumping Station of the Keelung River, and the reservoir water of the Sinshan Reservoir and the Sishih Reservoir. The water of the Badu pumping station is directly used for the Sinshan water treatment plant, and the excess water is stored in the Sinshan Reservoir. When water is insufficient during the dry season, water will be supplied from the reservoir.

The Xindian River belongs to the water supply district of the Taipei Water Department. In addition to the Taipei City, it also supplies water to several districts in New Taipei City (i.e. Sanchong District, Xindian District, Yonghe District, Zhonghe District and Xizhi District). Besides this river supports the First Branch of the Taiwan Water Coporation for Tamsui District, Xizhi District and Shenkeng District as well as the Twelfth Branch of the Taiwan Water Coporation for Zhonghe District and Luzhou District. Almost all of the water resources are from the Xindian River, and the water from the Nanshi Creek, a tributary of the Xindian River, is preferred. Water would be replenished from the Feitsui Reservoir, located along the Beishi Creek, as the water demand, supplied by the Nanshi Creek, could not be fully met.

The intake facilities of the Dahan River are the Shimen Reservoir (including the Zhongzhuang bankside storage pool), the Yuanshan weir, located in the downstream of the Dashan River, and the Sanxia River, a tributary of the Dahan River. Taoyuan City is the water supply area of the second branch of the Taiwan Water Corporation. The water is mainly transported through the Shimen Channel and the Taoyuan Channel.

The North Taoyuan area can be irrigated by the Yuanshan weir in addition to the Taoyuan Channel. The South Taoyuan area is irrigated by the Shimen Channel, with a supplement from the Sankeng Booster Station associated with the second pumping station. The Banqiao District and Xinzhuang District of the New Taipei City are supplied by the twelfth Branch of the Taiwan Water Coporation. Its water resource includes the Sanxia River Pumping station and the Yuanshan Weir. It also has pipes connecting the Taipei Area. When the amount of water in the streamflow is insufficient during the dry season, the Taipei Water Department can support the water supply through the pipe to reduce the pressure on the water supply of the Shimen Reservoir.

The Touqian River is the water supply area of the third branch of the Taiwan Water Coporation. Its main water source is the Touqian River, which is jointly supplied by the Longen Weir, the Baoshan Reservoir and the Baoshan Second Reservoir. The water mainly comes from the Longen Weir and can be supported by the Shimen Reservoir of Taoyuan and the Yongheshan Reservoir of Miaoli when water deficit occurs.

The water supply systems of the main irrigation channels include the irrigation water intake systems of the Shuangxi Creek, the Keelung River (Peikee Irrigation Association), the Dahan River (Taoyuan Irrigation Association and Shimen Irrigation Association), and the Touqian Creek (Hsinchu Irrigation Association). These systems are introduced as follows:

The Shuangxi and Keelung Irrigation Districts are located in the northeastern Taiwan and belong to the Peikee Irrigation Association. The main irrigation water sources are the Keelung River and the Shuangxi Creek. The main irrigation channels are the Wainan Shan Channel, the Dieyukeng Channel, the Sijiaoting Channel and the Bagusan Channel.

The irrigation area of the Dahan River is located in the downstream of the Shimen Reservoir. It belongs to the irrigation districts of the Taoyuan Irrigation Association and the Shimen Irrigation Association. The main irrigation channels are the Taoyuan channel and the Shimen channel, which are then subdivided into dozens of branch channels.
