Primary School Pin-Shi, Taiwan

Hsin-Chu, Taiwan | 2003

Since 2002, primary schools can apply for financing if they want to invest in environmental protection. Typical plans consist of facade constructions to provide passive heat insulation, biotopes and systems for rainwater harvesting. Meng-Tai Fu is one of 6,000 employees at the Industrial Technology Research Institute (ITRI). In consultation with Fu, an underground rainwater storage tank capable of holding 20 m³ was built at Pin-Shi primary school and connected to 440 m² of roof surface. Upstream from the storage tank, the rainwater is cleaned via a WISY FS filter collector and a WISY WFF 100 vortex fine filter.

The pupils are taught in the subject of environmental protection. This also involves recording the rainwater yield and the level of water in the cistern every week. Pupils are also able to provide information about how the water is used: 60% of water from the cistern is used for the toilets, while 40% is for irrigation. Pupils can fill their watering cans from three containers set up above ground that hold 250 l of rainwater each and water the plants in the school playground. This task is also part of the lessons on environmental protection. When the containers are empty, they are automatically refilled by a central pumping system in the cistern.
