Introduction: Rising Demand for Water Treatment in India
India is one of the fastest-growing economies in the world, but this growth comes with a serious challenge—water scarcity and water pollution. Rapid industrialization, urban expansion, population growth, and depletion of groundwater resources have made water treatment and wastewater treatment not just important, but essential.
Industries, residential societies, commercial complexes, hospitals, hotels, and municipalities are now legally and environmentally required to install RO plants, sewage treatment plants (STP), effluent treatment plants (ETP), water treatment plants (WTP), ultrafiltration (UF) systems, and water softeners.
As a result, the water treatment industry in India has grown rapidly, with hundreds of companies offering different technologies. However, only a few truly stand out based on experience, manufacturing capability, technology, compliance, and customer satisfaction.
In this detailed guide, we list the Top 10 Water Treatment Companies in India, carefully selected based on:
