Jeppinamogaru STP - Under-Construction Sewage Treatment Plant in Bajal, Karnataka

Jeppinamogaru STP is a sewage treatment plant currently under construction in Bajal, a locality in Mangaluru taluk, Dakshina Kannada district, Karnataka, India. The plant is designed to serve a population of 133,624, placing it in the category of a medium-to-large agglomeration under Indian urban wastewater management norms. As the plant is under construction, its treatment process and discharge volume are not yet operational. Under India's environmental regulations, sewage treatment plants of this scale are typically required to meet secondary treatment standards as per the Central Pollution Control Board (CPCB) guidelines, with potential for tertiary treatment if discharging into sensitive water bodies. The designed capacity is 1.00 million liters per day (MLD), indicating a facility sized for the projected population. The plant's location in coastal Karnataka means its treated effluent will likely discharge into a local watercourse that drains into the Arabian Sea. The region's high rainfall and proximity to the coast necessitate robust treatment to protect downstream ecosystems, including estuaries and marine habitats that support fisheries and biodiversity.

The plant is situated in the coastal belt of Karnataka, within the Netravati-Gurupura river basin, which ultimately drains into the Arabian Sea. The downstream environment includes estuaries and nearshore marine areas that support diverse aquatic life, including commercially important fish species. Effective wastewater treatment is critical to prevent nutrient loading and pathogen contamination in these sensitive coastal waters.
