Indirapuram Trans Hindon Wastewater Treatment Plant, Ghaziabad, Uttar Pradesh

Indirapuram Trans Hindon is a wastewater treatment plant located in Ghaziabad, Uttar Pradesh, India. It serves a population of approximately 494,000 residents in the Indirapuram area, making it a large-scale facility under Indian urban wastewater management standards. The plant is operational and plays a key role in managing domestic sewage from this rapidly growing suburban region east of Delhi. As a large agglomeration serving nearly half a million people, the plant is expected to provide at least secondary treatment under India's environmental regulations, which are aligned with the Water (Prevention and Control of Pollution) Act of 1974. The Central Pollution Control Board (CPCB) and Uttar Pradesh Pollution Control Board (UPPCB) oversee compliance, including effluent discharge standards for biochemical oxygen demand (BOD) and total suspended solids (TSS). Facilities of this scale typically employ activated sludge or similar biological treatment systems. The plant discharges treated wastewater into the Hindon River, a tributary of the Yamuna River, which ultimately flows into the Ganges. The Hindon River is heavily impacted by urban and industrial pollution from the Ghaziabad region. The plant's operation is critical for reducing pollutant loads and protecting downstream water quality, particularly as the Yamuna-Ganges system supports millions of people and diverse aquatic life.

The plant discharges into the Hindon River, which flows into the Yamuna River, a major tributary of the Ganges. The Hindon River basin is densely populated and faces significant pollution pressures from urban runoff and industrial effluents. The treated wastewater from this plant helps mitigate nutrient and organic loading, supporting the ecological health of the downstream Yamuna and Ganges systems, which are vital for drinking water, irrigation, and biodiversity.
