What's different about septic in San Marcos
Mixed ground. Alluvial soils near the San Marcos River give a conventional field a chance; move west or uphill and the limestone takes over.
Sewer status
City service ends at the limits. A San Marcos mailing address says nothing about whether a property is on sewer.
