The Eco-pro is a wastewater treatment plant by Noble Sovrano Ltd. It is based on MBBR technology that has been around since the early 80’s. It requires an Aerobic biological process by which micro-organisms grow in biofilms on prescribed media to accelerate treatment process. When you discharge kitchen and bathroom water straight into storm-water drainages, it comes back to hurt you by polluting underground water, same as when you allow sewage seep through underground suck-away tanks into the environment in densely populated towns or cities. It lead to: dysentery or diarrhoea outbreak, food contamination, underground water pollution, degradation of the environment and eventually, sicknesses and deaths.
