Title 30 Texas Administrative Code, Chapter 285, establishes a regulatory program for the management of OSSF's including minimum standards for planning materials, construction, installation, alteration, repair, extension, operation, maintenance, permitting, and inspection of OSSF's.  Victoria, Calhoun, and Dewitt counties are authorized agents of the Texas Commission on Environmental Quality(TCEQ). The authorized agent is responsible for implementing and enforcing the rules adopted under the Texas Health & Safety Code - Chapter 366

To fulfill this responsibility, the authorized agents have established an agreement with the Victoria County Public Health Department Environmental Services Division. The Victoria County Public Health Department Environmental Services Division currently has 6 licensed Designated representatives. These licensed individuals review permit applications, site evaluations, planning materials, and conducts inspections on OSSF's.

A homeowner or landowner will be required to follow the below process for an OSSF Installation: 

1) Selecting an OSSF System & Installer

The site and soil conditions determine the type of OSSF system that can be installed. A soil and site evaluator, licensed through the Texas Commission on Environmental Quality (TCEQ), is required to conduct a soil and site evaluation of the proposed site. Site and soil conditions include the type of soil (sand, sandy clay, clay, etc.), seasonal water tables, and restrictive horizons. There are several different types of OSSF systems including conventional (pipe and gravel), low pressure dosing, aerobic treatment with surface irrigation, and aerobic treatment with drip emitters. To locate a Licensed Site Evaluator and/or Installer you can search on the TCEQ website

2) Complete an OSSF Application

An application for a permit shall be submitted according to the process outlined in the On-Site Sewage Facility Application Packet provided by the Victoria County Public Health Department Environmental Services and must include the appropriate planning materials in accordance with 30 TAC § 285.5 of the State of Texas On-Site Sewage Facilities Rules and Regulatory Guidance [OSSF Rules].

Applications will be approved or denied within 30 days of receiving an application.  If the application is approved an Authorization to Construct will be issued.  If the application is denied we will notify the owner and Installer.

**Note: Incomplete applications will not be processed. Non-standard/Proprietary systems require a Professional Engineer or Registered Sanitarian design, and must be installed by an Installer that holds a Class II License from the State of Texas unless the homeowner is installing. A homeowner may install their own standard septic system but the owner must meet all permitting, construction, and maintenance requirements of the permitting authority.

3) Schedule an Inspection

An inspection should be called in no later than the 5th working day before the proposed date of the operation of the system.  Once the OSSF system has been inspected and is approved for operation, the system can be put in use.

OSSF Fees and Adoption


The United States Department of Agriculture Rural Development Program provides low interest home improvement loans and grants. This program is commonly referred to as the Section 504 Program, and is designed for very-low-income individuals living in non-metropolitan areas. The objective of the USDA Rural Development 504 Program is to help very low income owners of modest single family homes repair those homes. Loan funds are available to improve or modernize a home, make it safer or more sanitary, or remove health and safety hazards.

Our local County USDA Rural Development Office is located in Edna.  This office provides coverage in the following counties: Calhoun, DeWitt, Goliad, Gonzales, Jackson, Lavaca and Victoria.

Frequently Asked Questions:

Q)  How often should I pump my system?
A)  It’s recommended to pump your system every 3-5 years. If you have a maintenance provider maintain your system, they should notify you via inspection report when pumping is required.

Q)  Can I maintain my own system?
A)  Check with the permitting agency. Rental, commercial, multi-family, and systems with a variance must have an ongoing maintenance contract. The owner of a single family dwelling may maintain their own system. Property owners are encouraged to contact a maintenance provider for training on their system.

Q)  What do I do if my alarm is sounding?
A)  If your alarm is sounding, your OSSF needs attention. We recommend you contact your maintenance provider and limit your water usage. The alarm may be temporarily silenced. Refer to your maintenance contract for the response time specified by your maintenance provider. 

Q)  Can I make my own repairs to my OSSF?
A)  First contact the permitting agency before any repairs are made. A homeowner can make repairs from the home to the tank. Your drainfield cannot be repaired. Surfacing sewage above your drainfield is a good indicator that your drainfield is failing. Any work done to the drainfield requires the system to be brought up to current standards and may require a permit.

Q)  How often do I need to add chlorine bleach to my system?
A)  Depends on usage, but typically a gallon a month for a single family dwelling. 

Q)  Do I need a permit to install an OSSF on my property?
A)  Yes, with the exception of the 10 acre rule. No planning materials, permit, or inspection are required for an OSSF for a single family dwelling located on a tract of land that is 10 acres or larger and 1) the OSSF is not causing a nuisance or polluting groundwater; 2) all parts of the OSSF are at least 100 feet from the property line; 3) the effluent is disposed of on the property; and 4) the single family dwelling is the only dwelling located on that tract of land. 

Q)  Can I install my own system?
A)  A homeowner will be required to follow the permitting process for an OSSF installed for their single family residence. No one can be compensated for any part of the labor while constructing. Construction cannot begin until the approval to construct has been granted from the permitting authority. After the inspection and the approval to operate has been granted, the system can be used. If a maintenance contract is required, the first two years must be done by a licensed maintenance provider. An owner cannot install a system for multi-family or commercial/rental property. A financial institution may require an approval to operate from the homeowner prior to closing on the loan.
