The water source of the Tamsui campus, Taipei campus, and Lanyang campus of TKU mainly comes from rivers. The water is treated by reservoirs and public water purification plants and then turned into tap water. The quality of water is guaranteed by the Tap Water Law of Taiwan. The water source (reservoir) is sent to TKU for use through the following procedures:
1. Water intake: pumps the water into the water diversion channel with a water pump at the water source (or reservoir).
2. Water diversion: the process of sending water from the water source to the water purification plant.
3. Water purification: after the water enters the water purification plant, it undergoes purification procedures such as mixing, gelling, sedimentation, filtration, and disinfection to remove impurities and germs in the water.
4. Delivery (distribution) of water: the water is suitable for drinking after the water purification process and disinfection, known as tap water, and the tap water is distributed to the user through a pipeline.
In addition, a small amount of rainwater collected by the TKU’s building equipment is also used for irrigating campus plants. The total water consumption is 526,652,556 liters of tap water treated by the water plant in the river; a small part of it is collected by rainwater and used as sprinkler irrigation for plants, about 2,556 liters.
