On-site Sewage Facilities (OSSF)
When city sewer lines are not available to a residence (300 feet with gravity flow), an On-site Sewage Facility (OSSF), also known as a septic system, maybe an alternative. All OSSFs must be compliant with current State OSSF rules and City Ordinance. The Environmental Health Division accepts applications, reviews plans for new OSSFs, reviews plans for modifications of existing OSSFs, and conducts inspections as required. If you have any questions or concerns please call City of San Marcos Environmental Health at 512-393-8444.
