Cleaning Process

Alrode, Johannesburg

The polluted stormwater is collected from the industries and channeled to the main stormwater pipeline. The pipeline, that now has been updated and sloped in two degrees, conducts the water into the stormwater treatment plant. After the collection of the water in a reservoir and having pumped it up to the surface (utilizing the energy of the power lines), the treatment starts by using a set of physical filters and chemical procedures to trap inorganic and organic particles present in water. The water flows down by gravity through seven cleaning stations to finally go back to the wetlands after meeting the required effluent standards.
