Overview
Tonca wastewater treatment plant serves Panaji, Goa, India, with a designed capacity of 1.00 million liters per day, serving a population of 83,515. It is located within 50 km of the coast, discharging into the Mandovi River estuary.
Tonca wastewater treatment plant is located in Panaji, the capital city of Goa, India, along the Mandovi River estuary. It serves a population of approximately 83,515 people, making it a medium-sized agglomeration under Indian urban wastewater management standards. The plant is situated in the Miramar area, a coastal neighborhood known for its beaches and tourism. As per Indian environmental regulations, wastewater treatment plants serving populations above 50,000 are required to meet secondary treatment standards under the Water (Prevention and Control of Pollution) Act, 1974. The plant's designed capacity is 1.00 million liters per day, and it is currently operational. Plants of this scale in coastal areas typically employ biological treatment followed by disinfection to protect sensitive coastal ecosystems. The treated effluent from Tonca plant is discharged into the Mandovi River, which flows into the Arabian Sea. The Mandovi estuary supports diverse aquatic life, including mangroves and fish species, and is an important ecological corridor. The plant's proximity to the coast (within 50 km) underscores the need for effective nutrient removal to prevent eutrophication in the receiving marine waters.
Environmental context
The Tonca plant discharges into the Mandovi River, which flows into the Arabian Sea via the Zuari estuary. This coastal ecosystem supports mangroves, seagrasses, and diverse fish populations, and is a critical habitat for migratory birds. The plant's location within 50 km of the coast means that treated effluent must meet stringent standards to avoid nutrient loading and algal blooms in the sensitive marine environment.
