Introduction to Aerobic Treatment Units If an individual attempts to carry out maintenance activities that are beyond the scope of their training the results could include: Voided warranties Voided warranties Destruction of components Destruction of components Generating more problems with the system Generating more problems with the system Increased cost of repair Increased cost of repair Personal injury or even death. Personal injury or even death.
Homeowner Maintenance Exemption 285.7(d)(4) At the end of the initial two-year service policy period, the owner of an OSSF for a single family residence shall either maintain the system personally or obtain a new maintenance contract. Limitation: An owner may not maintain an OSSF under the provisions of this section for commercial, speculative residential, or multifamily property. You are managing a wastewater treatment plant: do you have effluent or sewage in your yard?
Permitting Wastewater Treatment Systems in Texas Texas Commission on Environmental Quality (TCEQ), Chapter 285, 5000 gallons per day or less Local Authorized Agent – Usually local Health Department Local Authorized Agent – Usually local Health Department TCEQ Regional Office TCEQ Regional Office TCEQ, Chapter 217, Greater than 5000 gallons per day.
Malfunction Malfunctioning OSSF – An on-site sewage facility that is causing a nuisance or is not operating in compliance with the 285 OSSF regulations.
Nuisance sewage, human excreta, or other organic waste discharged or exposed in a manner that makes it a potential instrument or medium in the transmission of disease to or between persons an overflow from a septic tank or similar device, including surface discharge from or groundwater contamination by a component of an on-site sewage facility; or a blatant discharge from an OSSF.
What is an Onsite Wastewater Treatment System? 1. Wastewater Source 2. Collection and Storage 3. Pretreatment components 4. Final Treatment and Dispersal components
Pretreatment Septic tanks Aerobic treatment units Media filters Constructed wetlands Membrane bioreactors Disinfection
Final Treatment and Dispersal Components Trench and bed distribution Evapotranspiration beds Low pressure distribution trench Drip field Spray field
How do we make the wastewater system work? Evaluate the wastewater source Evaluate site Wastewater treatment Wastewater treatment Wastewater acceptance Wastewater acceptance Choose a final treatment and dispersal component Choose the appropriate pretreatment system Operation and Maintenance
Roles with Septic System Management Site evaluation Design Installation Startup Inspection Operation Maintenance Monitoring Pumping
Site Evaluation Comprehensive evaluation of soil and site conditions for a given land use.
Design The process of selecting, sizing, locating, specifying and configuring treatment train components that match site characteristics and facility use as well as creating the associated written documentation. A design is also the written documentation of size, location, specification and configuration.
Installation The assembly and placement of components of a system, including final grading and establishment of an appropriate cover
Startup The process of setting operational controls, verifying component function and documenting initial operating conditions of a system
Inspection The evaluation of and reporting on the status of a wastewater treatment system
Operation The action of assessing whether each component of the system is functioning properly Each component must be operational if the system as a whole is to achieve the desired performance
Maintenance The action of conducting required or routine planned performance checks, examinations, upkeep, cleaning, or mechanical adjustments to an onsite system. Includes Replacement of pumps, filters, aerator lines, valves or electrical components.
Monitoring The action of verifying performance for a regulatory authority or a manufacturer
Pumping The action of removing septage from a wastewater treatment system component
Repair Is the action of fixing or replacing substandard or damaged components. Required repairs Required repairs Recommended repairs Recommended repairs Upgrades Upgrades
Why Perform Operation and Maintenance? Keep systems functioning properly Maintain effluent quality Early detection of problems Public Health Environmental Protection System Reliability Customer Satisfaction

Summary Decentralized management will play a vital role in our future infrastructure needs. Technologies are available for meeting our needs. Environmental regulations will continue to be more stringent. Environmental health is ultimate form of public health protection.
Summary A site evaluation is critical to determining the potential for a site to treat wastewater. Advanced pretreatment and final treatment and dispersal technologies are available for most situations. Select the most appropriate technology and scale of system for your site. Operation and maintenance is critical for long-term function
