Jefferson County Environmental Control Issues Septic Permits

If public sewer is unavailable, a Jefferson County home may need an on-site sewage facility, or OSSF. Ask Environmental Control who permits the address. Have the site checked to see which system will work. TCEQ sets the state standards.

For a new county-permitted system, get approval before work starts. The packet calls for a site plan, soil review, design, and installer information. Some systems need ongoing service. For those, include the required service contract and recorded affidavit. A final inspection comes before the county certificate.

Low, wet soil can change which design will work. Have the site evaluated before buying a raw lot, rather than assuming an ordinary septic tank will fit.
