This paper talks about the permitting challenges and utiliziation of MBR in order to meet surface water discharge permit requirements for Hays County, Austin, Texas. The discharge goes to an iconic landmark which provides year round recreational swimming in the heart of Austin and is home to the Barton Springs Salamander. This is the first surface discharge permit issued upstream of Barton Springs. All other wastewaters in the drainage basin are disposed of via irrigation, subsurface drip irrigation or septic tanks and drain fields. Obtaining the discharge permit was an arduous and controversial process pitting development interests in Hays County against environmental (non-development) interests in the region. The permit limits were most stringent and MBRs & Consent Agreement Keys to permit.
