Maintenance of On-Site Sewage Facilities (Septic Systems)
Two years after the initial installation of your aerobic treatment unit, maintenance can be performed by homeowners for systems that use secondary treatment systems, non-standard treatment systems, drip irrigation, and surface application disposal.
Note: Some permitting authorities have adopted more stringent requirements, which may require homeowner training or even a prohibition against homeowner maintenance. To check if your permitting authority has adopted more stringent requirements go to On Site Activity Reporting System.
- Who can I contract with to do maintenance on my OSSF?
- What does the licensed maintenance provider do?
- What should the contract specify?
- How do I become a licensed OSSF maintenance provider?
- How do I become a registered maintenance technician?
- What laws and rules govern OSSF maintenance?
- What type of chlorine should I use for wastewater disinfection?
- Should I pump my septic tank?
- Who can I call for more information?
The contract must be with a "licensed" maintenance provider. A maintenance provider is an individual person. At one time, TCEQ registered OSSF maintenance companies, but TCEQ no longer registers OSSF maintenance companies.
The maintenance provider is responsible for fulfilling the requirements of the maintenance contract.
At a minimum, the maintenance company or maintenance provider shall:
- Install a tag, or some other form of identification, on the system at the beginning of each maintenance contract;
- The indentification shall either be punched or marked at the time of each visit, including responses to owner complaints, to provide the owner with a record of the visit.
- Inspect components of the system and note whether or not every component is working during each site visit;
- If a component is not operating properly, the property owner must have it repaired.
- Test the system as required in 30 TAC §285.91(4);
- Submit a report to the permitting authority and owner at least once every four months [see 30 TAC §285.90(3)for a sample report];
- The reporting frequency may be reduced to once every six months if the system uses an electronic monitor, automatic radio or telephone to notify the maintenance provider of your system or component failure and to monitor the amount of disinfection in the system;
- The maintenance provider is responsible for ensuring that the electronic monitoring and automatic radio or telephone access systems are working properly.
- Your report must include all responses to property owner complaints and electronic monitoring notices;
- Your report must be submitted within 14 days after the test is performed.
The maintenance contract shall specify the following:
- List items that are covered by the contract;
- Specify a time frame in which the maintenance provider will visit the property in response to a complaint by the property owner regarding the operation of the system;
- Specify the name of the individual employed by the maintenance company who will be performing the maintenance on your system;
- Identify the frequency of routine maintenance and the frequency of the required testing and reporting; and
- Identify who is responsible for maintaining the disinfection unit.
A licensed maintenance provider is defined as a person who is in the business of maintaining OSSFs using aerobic treatment. In order to obtain the license, a person must:
- Hold a current Installer Class II (OSII), OR license,
- Hold a Class C or higher Wastewater Operator license OR.
- Have sucessfully completed three years as a registered maintenance provider(or maintenance technician).
The individual must also:
- successfully complete the TCEQ-approved Basic Maintenance Provider course;
- successfully complete a TCEQ-approved Advanced Aerobic System course;
- pass the licensing exam; AND
- submit a completed application for a licensed maintenance provider and a $111 application fee Texas Commission on Environmental Quality.
- Every individual performing maintenance under a licensed maintenance provider must be a registered maintenance technician, AND
- successfully complete the TCEQ-approved Basic Maintenance Provider course; AND
- work directly under the supervision of a licensed maintenance provider; AND
- submit a completed Application for Registration as an On-Site Sewage Facility(OSSF) Maintenance Technician and a $111 application fee to the Texas Commission on Environmental Quality. An application can only be obtained at the Maintenance Provider Training Course.
The statute regarding this requirement is Texas Health and Safety Code Section 366.0515.
The rule regarding the specifics of OSSF maintenance is 30 TAC §285.7.
When disinfection of secondarily treated wastewater effluent is required and you are using chlorine tablets, it is important that you use a chlorine tablet that is made from calcium hypochlorite and is certified for wastewater disinfection by EPA. They are very reactive and will kill 99% of the bacteria present in the effluent within 10 minutes. Follow all warning and precaution statements of the chlorine tablet manufacturer to protect yourself and the system equipment.
WARNING: DO NOT use swimming pool chlorine tablets in your disinfection system. The chlorine in these tablets are made from trichlorisocyanuric acid. Swimming pool tablets dissolve more slowly than calcium hypochlorite and do not thoroughly disinfect the effluent. Additionally, there is a danger of explosion using swimming pool tablets since the tablets will release an explosive gas called nitrogen chloride due to the fact that they are not totally immersed in water at all times while in use. They are not approved by EPA for wastewater effluent disinfection.
For conventional systems, it is recommended that you pump your septic tank every three to five years to prevent short circuiting of the treatment process. Access the online database to obtain a list of registered sludge transporters in your area.For aerobic treatment units, it depends on the depth of sludge and manufacturer's recommendations.
