Texas Counties Deliver


Along with the mandatory Development Permit (Floodplain Permit), anyone needing to construct or replace an OSSF (On-Site Sewage Facility) will also need to have a permit on file with this office.  In Lavaca County all parcels of property needing an OSSF will need to obtain a permit to install, replace or repair the on-site sewage facility.  No homeowner is allowed to install or maintain their On-Site Sewage Facility or maintain it after installation if the system requires it.  All septic permits must be applied for through a TCEQ licensed professional OSSF installer of your choice.  The choice of system is based on the soil evaluation that will be conducted on the proposed location where the system will be installed.  Lavaca County does have an Ordinance on file regarding On-Site Sewage Facility Regulations and Lavaca County understanding the technical criteria, legal requirements, and administrative procedures and duties associated with regulating all OSSF’s, accepts the responsibility of enforcing any and all Texas Health & Safety Codes, Texas Water Codes and Texas Administrative Codes relating to the On-Site Sewage Facility Regulations.
