Which of the following best describes the institution’s approach to rainwater management?:
Less comprehensive policies, plans or guidelines that incorporate green infrastructure
A brief description of the institution’s green infrastructure and LID practices:
In Taiwan, under subtropical weather, trees and lawns on campus can benefit from rainwater directly, and the lakes connected through creeks provide water for additional watering.
The total area of the campuses is 296.5272 acres, and the area of vegetated grounds is 100.4245 acres. Some areas retain the original forests. The hydrological method of natural environment retention and interception is used to delay rainfall peaks. The development areas are scattered interconnected by forest green to absorb the surface rainwater inflow, and in turn, to reduce the impact from heavy and peak raining. There are five lakes spreading around the campus, which work as detention ponds besides the beautiful recreation sites. In the south campus, grass ditches and grass belts are installed to replace concrete drainage facilities, which can increase the amount of surface infiltration and reduce environmental impact.
Rainwater is also collected for irrigation on green roof gardens, in which the Green Roof team in residential colleges designed and implemented the system. They will extend their green roof project to the Education Building, where the solar panel facility will generate electrical power for watering and lighting. These practices will equip students with sustainability skills to make the best use of water.

A brief description of the institution’s rainwater management policy, plan, and/or guidelines that supports the responses above:
The campus built took advantage of the original topography of low slope from the south and the north, and there are waterways in the campus that connect multiple open water bodies to form lakes. The advantage of the terrain is used to collect rainwater in the area. For example, instead of irrigating for planting and landscape maintenance using tap water, the campus can benefit from rainwater to provide groundwater for trees and grass.
The total area of the campus is 296.8 acres, and the area of vegetated grounds is 100.4245 acres. The amount of water needed for irrigation is 214,681.268 gallons, and the annual water demand is 78,358,664 gallons. However, considering that the campus is located on a hillside and has abundant groundwater resources, the forest vegetation on the campus is good, and the effect of water conservation can be adopted. There are many open water bodies within the campus, which can store rainwater to replenish the groundwater source without the need for additional watering from tap water.
