The plant serves a population of approximately 1,369 people, reflecting its role in managing domestic wastewater for this small community. The plant provides secondary treatment, a standard level for communities of this size in Mexico. With a designed capacity of 129.60 cubic meters per day and a discharge volume matching that figure, the facility operates at full capacity. Mexican wastewater treatment plants are regulated under the Federal Law for the Prevention and Control of Environmental Pollution and the National Water Law, which set effluent quality standards for discharge into water bodies. The treated effluent from PTAR Huazalingo is discharged into local waterways that eventually drain into the Gulf of Mexico. The region's rivers and streams support diverse aquatic life and are important for local agriculture and ecosystems. Proper treatment helps protect downstream water quality and public health.

The plant discharges into the local watershed within the Pánuco River basin, which flows northeastward into the Gulf of Mexico. This coastal basin supports diverse aquatic habitats and is used for agriculture and fishing. Effective secondary treatment reduces organic pollutants and pathogens, safeguarding downstream communities and ecosystems.
