Short answer
If your property isn't connected to a municipal sewer line — common on rural land, acreage, and where you're setting a new or manufactured home — you need an on-site septic system to legally handle wastewater. Most rural Texas homes use one.
When you need one
Any home without access to city sewer needs its own on-site sewage facility (OSSF). That includes new construction on raw land, acreage, and manufactured or mobile homes set on rural lots.
How to check
Ask your county or local utility whether a public sewer line serves your address. If there's no sewer tap available, you'll install a septic system.
What happens next
We run a soil and perc test, design and size the system to your home and soil, pull the county permit, install it, and see it through final inspection.
