Plant Background and Operation
LCRA built the Wastewater Treatment Plant using SBR technology. The plant had a capacity of 400,000 gallons per day.
The City of Liberty Hill purchased the plant from LCRA.
To provide additional capacity to support the city’s growing population, the City upgraded the system to a capacity of 1,200,000 gallons per day and added MBR technology.
The Liberty Hill Wastewater Treatment Plant is currently undergoing a $12.2 million expansion to increase capacity to 2,000,000 gallons per day to keep up with demand and to upgrade odor control. The older SBR Technology has been decommissioned.
New MBR technology is currently operating as an active treatment plant.
