Sullia Mangalore Wastewater Treatment Plant, Sulya, Karnataka

Sullia Mangalore is a wastewater treatment plant currently under construction in Sulya, Karnataka, India. Located in the Dakshina Kannada district, the facility is designed to serve a population of approximately 90,946, addressing the wastewater management needs of this urbanizing area. The plant is part of India's broader efforts to improve sanitation infrastructure under national programs like the Swachh Bharat Mission. As a plant under construction, specific treatment processes and capacity details are not yet finalized. However, for a facility serving nearly 91,000 people, Indian regulatory standards typically require secondary treatment or higher, in line with the Central Pollution Control Board (CPCB) norms. The designed capacity is 1.00 million liters per day, indicating a medium-scale facility that will likely incorporate biological treatment processes to meet discharge standards. The plant's treated effluent will eventually drain into local water bodies within the Netravati River basin, which flows westward to the Arabian Sea. This region supports diverse aquatic life and is important for local agriculture and drinking water supplies. Proper treatment at this plant will help protect downstream ecosystems and reduce pollution loads in the river system.

The plant is situated in the Netravati River basin, which drains into the Arabian Sea near Mangalore. The downstream environment includes estuarine and coastal habitats that support fisheries and biodiversity. Effective wastewater treatment is crucial to prevent nutrient loading and contamination in these sensitive waters, which are also used for irrigation and domestic water supply.
