San Pedro Itzican is a municipal wastewater treatment plant located in the town of San Pedro Itzicán, within the municipality of Poncitlán in the state of Jalisco, Mexico. The plant serves a population of 5,476 residents, placing it in the small agglomeration category under Mexican wastewater regulations. The plant provides secondary treatment, which is the standard level required for municipal wastewater in Mexico under the official standard NOM-001-SEMARNAT-1996. It has a designed capacity of 518.40 cubic meters per day and treats a similar volume of wastewater daily. As a coastal facility within 10 km of the Pacific Ocean, the plant's discharge is subject to stringent effluent quality limits to protect marine ecosystems. The treated effluent from San Pedro Itzican ultimately drains into the Pacific Ocean via local waterways. The plant plays a key role in safeguarding the coastal environment and the health of nearby communities by reducing pollutant loads before discharge. Its operation supports the ecological integrity of the region's coastal waters.
Environmental context
The plant discharges treated wastewater into local watercourses that flow into the Pacific Ocean. This coastal region supports diverse marine life, including fish and crustacean populations important for local fisheries. The plant's secondary treatment helps reduce organic matter and suspended solids, mitigating eutrophication risks and protecting nearshore habitats from excessive nutrient loading.
