Ecological Purification System in Samoa

Ecological Purification Systems (EPS) is commonly used by the Water Authority in Samoa for water treatment. Water is naturally purified through use of micro-organism established on the sand filter after heavy settable solids were removed at the settling and roughing pre-treatment filters. The system has many advantages from the viewpoint of cost, energy, chemicals and environment; however, it is prone to high turbidity but can be managed by adding appropriate size sedimentation tanks and roughing filters. The Samoa Water Authority continues to invest in EPS systems by implementing small scale EPS in isolated rural communities.
