Block No 1_P 11_P 13to19 at Asarma Ta Choryasi Dist Surat Wastewater Treatment Plant, Chorasi Taluka, Gujarat

Block No 1_P 11_P 13to19 at Asarma Ta Choryasi Dist Surat is a municipal wastewater treatment plant located in Chorasi Taluka, Surat district, Gujarat, India. The plant serves a population of approximately 100,218, classifying it as a large agglomeration under Indian urban wastewater management standards. It is situated in the industrial and urban corridor of Surat, a major city in western India. The plant has a designed capacity of 1.00 million liters per day (MLD) and is currently operational. Indian regulatory standards under the Environment Protection Act and the National Green Tribunal guidelines require that plants of this scale provide at least secondary treatment to meet discharge norms. The plant likely operates under the oversight of the Gujarat Pollution Control Board (GPCB), which issues consent to operate and monitors effluent quality. The treated wastewater from this facility is discharged into local water bodies that eventually drain into the Gulf of Khambhat (Cambay) via the Tapi River system. The Gulf of Khambhat is a shallow, macro-tidal estuary that supports diverse marine life and is an important fishing ground. The plant's operations contribute to protecting downstream ecosystems from untreated sewage, particularly in the sensitive coastal zone of the Arabian Sea.

The plant's treated effluent flows into the Tapi River basin, which drains into the Gulf of Khambhat on the Arabian Sea coast. The Gulf of Khambhat is an ecologically productive estuary supporting mangroves, fisheries, and migratory bird populations. The region is subject to high tidal influences, and nutrient loading from upstream sources can impact coastal water quality. The plant's location within 50 km of the coast underscores the importance of adequate treatment to prevent eutrophication and protect marine biodiversity.
