Tesla is discharging treated wastewater from its lithium refinery into a roadside drainage ditch, a practice that is permitted by state regulators but has raised concerns among local officials who say they were not notified, Inside Climate News reported.
The Texas Commission on Environmental Quality has authorized Tesla to release up to about 231,000 gallons of treated wastewater per day from its facility near Robstown. State investigators have found no violations of that permit.
However, the controversy centers on how the wastewater is being transported. Officials with a local drainage district say they were unaware that a pipe connected to the Tesla site had been installed and used to discharge into the ditch, which flows into Petronila Creek and eventually Baffin Bay.
Workers first noticed the discharge during routine maintenance, describing the liquid as dark in appearance. While water observed farther downstream appeared clear, officials noted increased algae and vegetation growth in the area, which can signal changes in water quality.
The state permit allows the discharge itself but does not grant permission to use land or drainage infrastructure without local approval. Local authorities are now questioning whether Tesla had the right to install and operate the pipeline without their consent.
The situation highlights ongoing tensions between state-level permitting and local oversight, as well as broader concerns about environmental impacts tied to industrial wastewater.
