Septic & Wastewater
Rural Lots Usually Need a Septic System Permit
Most rural properties in Milam County that are not on a public sewer line need a permitted on-site sewage system before building.
In Texas, a septic system is officially called an on-site sewage facility, or OSSF. Most rural lots in Milam County are not connected to a city sewer line. Those lots need a permitted septic system before a home can be built or a certificate of occupancy issued. The county or a designated agent handles permits. The rules come from TCEQ, the state environmental agency.
There is one limited exemption. A single-family home on a tract of 10 acres or more may not need a permit. But the home still must meet all state standards. Even on large tracts, you must follow rules for setbacks, system type, and soil testing.
Before buying rural land in Milam County, find out if a permitted septic system is already in place. If not, check what the soil can support. Contact TCEQ or the county for current local program details.
