The regional wastewater system in the Camp Swift area north of the City of Bastrop is currently being expanded by the LCRA. The expanded system will serve many of the homes in this area that currently have septic systems and unimproved lots.
DESCRIPTION
The Camp Swift MBR is located in Bastrop County and provides services to homes, the Texas National Guard, a medium‐security federal prison and a University of Texas cancer research facility. The Lower Colorado River Authority (LCRA) upgraded its Camp Swift Wastewater Treatment Plant (WWTP) lagoon with a Submerged Membrane Bioreactor (MBR) System. The treatment capacity of this new MBR system is 0.35 million gallons per day (MGD) and the lagoon continues to handle the remaining influent flow. The effluent is discharged for feed grass irrigation which is then collected for livestock.
