Galmoe Secondary School, South Korea

In October 2002, the Oasis School Project began, an idea of Prof. Mooyoung Han. He teaches water quality management and water recycling technology at Seoul National University in South Korea. His intention was to create a pilot project with Galmoe Middle School, following the example of all schools in Korea collecting rainwater to use for cleaning, garden and pond. The Oasis School Project also provides for a minimum amount of water to remain in the underground rainwater storage tank for emergencies. This could be a fire or earthquake, or a drinking water emergency in the country.

The rainwater from the flat roof of the school building is cleaned by parallel installed WFF 150 vortex fine filters from WISY AG on its way to the cistern. The filters are installed under the school's car park and can be easily inspected for cleaning purposes. Prof. Han's students regularly conduct investigations at this property to optimise rainwater harvesting technology. The results should be of help to the planning engineers of future projects.
