An example of how we make a difference in communities, is our new partnership with Emater in Brazil to build a septic tank for waste water treatment. The project aims to reduce the environmental consequences of waste water in rural communities. The system consists of a tank built with layers of rubble, gravel, sand and soil. Sewage is collected in a chamber, filled with tyres and debris, where it decomposes and is treated by micro-organisms. Water is absorbed by the roots of plants grown in the tank and released into the environment, without infiltrating the soil, avoiding contamination of the water table. The project is simple to build, low cost and highly efficient in treating sewage, as well as reusing nutrients to grow ornamental plants. This solution is a more sustainable method of sanitation in rural communities, preserving soil and water resources, and requires little maintenance and integration into the local landscape.
