Since 2009 the Lao Institute for Renewable Energy (LIRE) collaborates with BORDA (Bremen Overseas Research and Development Association) to disseminate Decentralized Wastewater Treatment Solutions (DEWATS) to reduce illnesses which are related to insufficient sanitary conditions and environmental pollution by sewage and wastewater. To impart a better understanding about the DEWATS approach a camera team accompanied our engineers and community facilitators to create a video which visualises our work. The video shows our DEWATS-engineers and community facilitators during the whole process of implementation at Khoualuang Primary School in Vientiane Capital, Lao P.D.R.
Khoualuang Primary School's compound was flooded up to 30cm height after every heavy rain. The surrounding canal system was to shallow both to deal with the high amount of solid waste and to cover high amounts of water coming from the main road and the neighbored area. As a result bad odor occurred and the surrounding area was steadily polluted. Last but not least, toilets and basins were in very bad condition so that a save and hygienic use was not possible. In the context of School Based Sanitation (SBS) DEWATS has been successfully implemented as a cost-effective, low maintenance solution for wastewater treatment. Now, pupils and teachers of Khoualuang Primary School can teach, learn and play in a school with improved sanitation and a clean environment.
