Kureepuzha Wastewater Treatment Plant, Kollam, Kerala

Kureepuzha is a proposed wastewater treatment plant located in Mathilil, Kollam, Kerala, India. Designed to serve a population of 77,502, the plant is part of the city's efforts to improve sanitation and water quality. As a proposed facility, it is not yet operational but represents a significant investment in the region's wastewater infrastructure. The plant's designed capacity is 1.00 million liters per day, though the treatment process has not been finalized. In India, wastewater treatment plants serving populations of this scale typically operate under the National River Conservation Plan or state-level pollution control board regulations. Such plants are expected to meet effluent standards set by the Central Pollution Control Board (CPCB) for discharge into inland water bodies. Once operational, Kureepuzha will treat wastewater from Kollam, with treated effluent likely discharged into the Ashtamudi Lake or the Kallada River, both of which drain into the Arabian Sea. The region's backwaters and coastal ecosystems are ecologically sensitive, supporting diverse aquatic life and local fisheries. Proper treatment is essential to prevent nutrient loading and protect these valuable water resources.

Kureepuzha's treated wastewater will likely be discharged into the Ashtamudi Lake or the Kallada River, which flow into the Arabian Sea. The Ashtamudi Lake is a large estuarine system that supports rich biodiversity, including mangroves and migratory birds. Protecting this ecosystem from untreated sewage is critical for maintaining water quality and the livelihoods of local fishing communities.
