Kirby Creek WWTP - Lometa, Texas Wastewater Treatment Plant

Kirby Creek WWTP is a municipal wastewater treatment facility located in Lometa, Texas, a small community in Lampasas County. The plant serves a population of approximately 670 residents, reflecting its role in managing wastewater for a small rural agglomeration. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater facilities. With a designed capacity of 378.54 thousand cubic meters per year and an actual discharge volume of 166.56 thousand cubic meters per year, the plant operates well below its capacity, indicating room for future growth or seasonal variability. The treated effluent is discharged into a local waterway that ultimately drains into the Colorado River basin, which flows through central Texas to the Gulf of Mexico. The plant's operations help protect downstream water quality in a region characterized by limestone geology and sensitive aquatic habitats.

The plant discharges into a tributary of the Colorado River, which flows southeast through Texas to Matagorda Bay and the Gulf of Mexico. The Colorado River supports diverse fish species and provides critical habitat for migratory birds. The surrounding Lampasas County area features karst topography, making groundwater protection a key concern for local water resources.
