Galmoe Middle School, South Korea

Uiwang City, South Korea | 2002

The Oasis School Project, an idea by Prof. Mooyoung Han, began in October 2002. He teaches Water Quality Management and Water Recycling Technology at Seoul National University in South Korea. His issue was to develop a pilot project together with Galmoe Middle School. Based on this example, all schools in Korea would harvest rainwater to be used for cleaning purposes, and for the garden and ponds. The Oasis School Project also ensures that a minimum amount of water for emergencies remains in the underground rainwater storage tank. Such an emergency could be fire or an earthquake, or a drinking water crisis in the country.

The rainwater is collected from the flat roof of the school building. On its way to the cistern, it passes through parallel installed WFF 150 vortex fine filters by WISY AG and is cleaned. The filters are installed underneath the school's car park and can be easily removed for cleaning purposes. Prof. Han's students regularly carry out inspections in order to optimise the rainwater utilisation. The results should be of value to planning engineers for future projects.
