Wastewater Treatment in India

H2O Alert! Why India Has to Change the Way it Looks at Water

Page: 3/4

Treatment of wastewater has become a moral responsibility for industries and municipal corporations as well. Advisor, Xylem Water Solutions India Pvt Ltd, AP Singh comments, “The wastewater treatment market for a developing country like ours has a wide scope for the development of new technologies. Due to this, organizations are constantly carrying out research and coming up with innovative new solutions.”

Now trending: #ZLD

A 2011 FICCI report states that only 60 per cent of industrial wastewater, mostly large scale industries is treated and re-used. However, now the situation seems to be changing with the introduction of the Zero Liquid Discharge (ZLD) concept – a water treatment process in which the entire wastewater is purified and recycled.

Kulkarni elaborates, “As a regulator, we are promoting the zero liquid discharge policy so that zero discharge takes place; this is a distant dream for us. However, many industries are carrying out this technique on their own and have been recycling their wastewater.”

Supporting Kulkarni, Singh adds, “Owing to government regulations and escalating ground water costs, most of the leading industries have already implemented or are in the process of implementing zero liquid discharge.” In Gujarat too, certain industries are following this concept and are running successfully as it’s a good business model. Senior Environmental Engineer, Gujarat Pollution Control Board, VR Ghadge says, “Gujarat is also working towards developing a zero liquid discharge policy to encourage industry players to invest in this new technique.”

Opportunities and Hurdles

Major government projects such as the Clean Ganga project, development of 100 smart cities and the establishment of industrial corridors are some of the major opportunities for players who deal in the wastewater treatment industry. Singh explains, “Smart cities are a major opportunity for the municipal segment as one can opt for a sewage treatment plant, treat the water and then send it across to the industries for their usage.”

In addition to this, Soundararajan gives us another example of this model, he says, “In Tamil Nadu, the Coimbatore Municipal Corporation is already implementing this model and selling the treated water to the industries. With this, the corporation is also making money.”
