Nathdwara Wastewater Treatment Plant, Bhalawaton ka Khera, Rajasthan

The Nathdwara wastewater treatment plant is located in Bhalawaton ka Khera, within the Nathdwara Tehsil of Rajsamand district, Rajasthan, India. It serves a population of approximately 28,729 people, classifying it as a medium-sized agglomeration under Indian urban wastewater management frameworks. The plant's construction is completed, indicating readiness to manage municipal sewage from the area. As a facility in India, the plant is subject to the Water (Prevention and Control of Pollution) Act, 1974, and the Environment Protection Rules, 1986, which set discharge standards for treated wastewater. For a population of this scale, secondary treatment is typically required to meet biochemical oxygen demand (BOD) and total suspended solids (TSS) limits before discharge. The regulatory framework ensures compliance with national standards. The treated effluent from the plant is likely discharged into a local watercourse that eventually drains into the Banas River, a tributary of the Chambal River, which flows into the Yamuna and then the Ganges. This downstream connectivity highlights the plant's role in protecting the Ganges basin ecosystem, which supports diverse aquatic life and provides water for millions of people. The region's semi-arid climate makes water reuse and conservation critical.

The plant's treated effluent likely enters a local stream that feeds into the Banas River, a key tributary of the Chambal River within the Ganges basin. The Chambal River supports a rich diversity of aquatic species, including the Ganges river dolphin and gharial, and is an important migratory corridor. Downstream, the Yamuna and Ganges rivers provide water for drinking, agriculture, and industry, making effective wastewater treatment essential for public health and ecological balance in the region.
