Tamazula de Victoria Wastewater Treatment Plant, Durango, Mexico

The Tamazula de Victoria wastewater treatment plant is located in the city of Tamazula de Victoria, in the state of Durango, Mexico. It serves a population of 1,278 people, classifying it as a small-scale municipal facility. The plant is situated in an inland area, far from coastal zones, and its operations are part of the local water management infrastructure. The plant provides secondary treatment, which is the standard biological treatment process for removing organic matter and suspended solids. With a designed capacity of 172.80 cubic meters per day and an actual discharge volume of 120.96 cubic meters per day, the plant operates below its full capacity. In Mexico, wastewater treatment plants are regulated under the National Water Law (Ley de Aguas Nacionales) and the official standards NOM-001-SEMARNAT-1996, which set discharge limits for pollutants into national waters. The treated effluent is discharged into a local water body, likely a river or stream within the Tamazula River basin, which ultimately drains into the Pacific Ocean. The plant plays a crucial role in protecting the local aquatic environment and public health by reducing pollution loads before discharge.

The plant discharges into a local watercourse within the Tamazula River basin, which flows through the Sierra Madre Occidental region. This watershed supports diverse aquatic life and provides water for agricultural and domestic use downstream. The treated effluent helps maintain water quality in the river system, which eventually drains into the Pacific Ocean, contributing to the health of coastal ecosystems.
