The Central Texas Treatment Center (CTTC) of Williamson County was established in November, 1990, to provide 24-hour community supervision and treatment to serious alcohol and drug abusers sentenced by the courts as an initial condition of community supervision or as a community supervision modification. CTTC was established through the joint efforts of the Texas Department of Criminal Justice-Community Justice Assistance Division (TDCJ-CJAD), the Community Supervision and Corrections Department (CSCD) of Williamson County and the Georgetown Healthcare System (GHS). 

On September 1, 2002, CTTC was relocated to Eastern Williamson County.  The physical and mailing addresses are as follows:

601 North Alligator, CR355
PO Box 488
Granger, Texas  76530
(512) 943-1211

The maximum bed capacity was increased to 100 on September 1, 2003.


The program design for CTTC consists of the criminal justice system, substance abuse treatment, adult education, cognitive learning, life skills training, psychological services, physical education and spiritual development. The treatment approach involves two tracks: community supervision and substance abuse/criminal thinking treatment. These two tracks are integrated to accommodate the philosophies of both disciplines resulting in the successful recovery and reintegration of the resident into society. Supervision and treatment functions provide a structured environment, teaching responsibility, consequences of actions and compliance with conditions of supervision.
