Welcome to ossfdesign.com

OSSFdesign.com is a website dedicated to sharing an understanding of the On-Site Sewage Facility (OSSF) Permitting process for some of the agencies local to the Austin/Central Texas area and explaining some of the types of systems most commonly installed. 



An OSSF is a system that treats no more than 5,000 gallons of sewage per day and is used only for the disposal of sewage produced on a site where any part of the system is located.  Because the rules that govern the installation of OSSF's in the State of Texas are very comprehensive and rigid, OSSF's planning is an integral part of the site plan for any site that isn't served by sewer.
