Delawas II Wastewater Treatment Plant, Jaipur, Rajasthan

Delawas II is a wastewater treatment plant located in Sitapura, within the Jaipur Municipal Corporation area of Rajasthan, India. Serving a population of 88,176, the plant is part of the urban infrastructure supporting one of India's major cities. The facility is operational and plays a key role in managing domestic wastewater from the surrounding area. As a plant serving a medium-sized agglomeration, Delawas II is expected to comply with India's Central Pollution Control Board (CPCB) standards for wastewater treatment. These standards typically require secondary treatment for such population scales, with provisions for tertiary treatment in sensitive areas. The regulatory framework ensures that treated effluent meets prescribed discharge norms. The treated wastewater from Delawas II is likely discharged into a local watercourse that eventually drains into the Yamuna River basin, which is part of the larger Ganges River system. The region's semi-arid climate makes water reuse and quality management particularly important for sustaining local agriculture and groundwater resources.

The plant is located inland in the semi-arid region of Rajasthan, where water resources are scarce. Treated effluent likely flows into a tributary of the Yamuna River, which ultimately joins the Ganges River. The downstream environment supports diverse aquatic life and is used for irrigation, making proper treatment essential to prevent nutrient loading and contamination of groundwater.
