Overview
SEAPAL Zona Norte I is a wastewater treatment plant serving Puerto Vallarta, Jalisco, Mexico. It serves a population of 109,527 and is located within 50 km of the Pacific coast.
SEAPAL Zona Norte I is a municipal wastewater treatment plant located in Puerto Vallarta, Jalisco, Mexico. It serves a population of approximately 109,527 residents in the northern zone of the city, which is a major tourist destination on the Pacific coast. The plant is part of the SEAPAL (Sistema de Agua Potable y Alcantarillado de Puerto Vallarta) utility system. As a large agglomeration serving over 100,000 people, the plant operates under Mexico's federal water regulations (Ley de Aguas Nacionales) and NOM-001-SEMARNAT standards, which set discharge limits for wastewater into national waters. Plants of this scale typically employ secondary or advanced treatment to meet regulatory requirements for coastal discharge. The plant's treated effluent likely discharges into the Pacific Ocean via local drainage systems or the Ameca River basin. Puerto Vallarta's coastal location means the plant plays a critical role in protecting marine ecosystems, including nearby Banderas Bay, which supports diverse aquatic life and is an important area for tourism and fisheries.
Environmental context
The plant is located within 50 km of the Pacific coast, with discharge likely reaching Banderas Bay, a large bay that supports coral reefs, mangroves, and diverse marine species. The bay is an important migratory corridor for humpback whales and sea turtles. Proper treatment is essential to prevent nutrient pollution and protect coastal water quality in this ecologically sensitive region.
