EcoAsia had a range of technologies suitable for schools, universities and colleges. Periodic gastrointestinal disease, such as virulent shigella, can spread quickly though communities of students where contaminated water or insufficient waste disposal is a problem. As populations expand, and educational infrastructure ages, so old sewerage or waster disposal systems become overloaded and fail, contaminating water. Children are too precious. Educational planners should familiarize themselves with our products and ask for the technical specifications.
