Delhi, the capital city of India, is one of the most densely populated metropolitan regions in the world. With over 20 million residents, rapid urbanization, growing industries, and increasing commercial hubs, the city generates massive volumes of sewage and wastewater every single day. Managing this wastewater is critical to maintaining public health, sanitation, and environmental safety.
This is where Sewage Treatment Plants (STPs) come into play. These plants treat wastewater to remove contaminants, harmful microorganisms, and organic matter before safely discharging or reusing the treated water. In Delhi, the demand for efficient, eco-friendly, and advanced STP systems has skyrocketed over the years, leading to the growth of several reputed manufacturers.
