Kuelher Road South WWTP - New Braunfels, Texas Wastewater Treatment

Kuelher Road South WWTP is a municipal wastewater treatment facility located in New Braunfels, Texas, serving a population of around 15,000. The plant is situated in Comal County, part of the rapidly growing San Antonio-New Braunfels metropolitan area, and plays a key role in managing local wastewater from residential and commercial sources. As a US-based facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting, typically administered by the Texas Commission on Environmental Quality (TCEQ). For plants serving approximately 15,000 people, secondary treatment is the standard requirement, ensuring effective removal of organic matter and suspended solids before discharge. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Guadalupe River. The Guadalupe River flows southeast through Texas and empties into the San Antonio Bay, part of the Gulf of Mexico. This river system supports diverse aquatic life and provides recreational and drinking water resources for downstream communities.

The plant's discharge enters the Guadalupe River basin, which flows through the Texas Hill Country and coastal plains before reaching the San Antonio Bay estuary. This watershed supports a variety of fish and wildlife, including the endangered fountain darter and other species dependent on clean water. The Guadalupe River is also a critical water source for agriculture and municipalities downstream, making effective wastewater treatment essential for maintaining water quality and ecological balance.
