Organized Sewage Collection System Plan
What is an Organized Sewage Collection System (SCS)?
An organized sewage collection system (SCS) is any public or private sewerage system for the collection and conveyance of sewage to a treatment and disposal system that is regulated pursuant to rules of the commission and provisions of Chapter 26 of the Texas Water Code . A system includes:
- lift stations,
- force mains,
- gravity lines, and
- all appurtenances necessary for conveying wastewater from a generating facility to a treatment plant.
A private sewerage system is the portion of the sewage system for a privately owned commercial, industrial, or multifamily development which extends downgradient from the convergence of two or more private service laterals from wastewater-generating facilities. This sewage collection system must be designed to meet the requirements of 30 TAC Chapter 217 and 30 TAC Chapter 213 .
What is an SCS plan?
An SCS plan is a detailed plan that outlines best management practices that will be implemented in order to protect water quality when an organized SCS is constructed in the Edwards Aquifer recharge zone.
Who is required to prepare and submit an SCS plan?
You are required to submit an SCS plan if you plan to construct an SCS over the recharge zone of the Edwards Aquifer.
When should an SCS plan be submitted to the TCEQ?
An SCS plan must go through the application submission and review process and be approved prior to the commencement of construction.
How much is the fee?
The fee is assessed at $0.50 per linear foot. The minimum fee is $650; the maximum, $6,500. For additional information on fees, view the Application Fee Form TCEQ-0574 (PDF, Word), which includes a complete fee schedule.
How do I know what forms to complete?
Use the forms listed below to prepare your SCS plan application.
If you are installing an underground storage tank, an aboveground storage tank, or conducting other regulated activities, review the Edwards Aquifer Protection Plan - Required Forms Flowchart to determine if additional forms are required.
Are there any tips for completing this type of plan?
- Do not leave any questions unanswered. If a question does not apply to your site, enter “N/A” in the blank and briefly explain why the question does not apply.
- SCS plans are not required on the Edwards Aquifer transition or contributing zone.
- A private service lateral (attachment of one wastewater generating structure to an existing sewage collection system line) does not require TCEQ approval, but must comply with local plumbing codes.
- The construction plans for the system, which are included with the submission must be designed, sealed, signed, and dated by a Texas licensed professional engineer. The designed plans must be the final plans intended to be used for bidding purposes.
