Alvarado WWTP - Advanced Wastewater Treatment in Johnson County, Texas

Alvarado WWTP is an advanced wastewater treatment plant located on County Road 404 in Johnson County, Texas, serving a population of 3,216. The facility operates under the regulatory framework of the US Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges into surface waters. The plant employs advanced treatment processes, providing a higher level of pollutant removal than secondary treatment. With a designed capacity of 2,271.24 thousand cubic meters per year, the current discharge volume of 870.65 indicates operational capacity is well within design limits. The treated effluent is discharged into local waterways that ultimately drain into the Trinity River basin, supporting downstream ecosystems and water quality in the region. The plant's inland location reduces direct marine impact, but its discharge contributes to the overall health of the watershed.

The plant discharges into local streams that are part of the Trinity River basin, which flows southeast through Texas to Trinity Bay and the Gulf of Mexico. The receiving waters support diverse aquatic life and are used for recreation and water supply. The advanced treatment helps protect downstream water quality in this ecologically sensitive region.
