An organized sewage collection system (SCS) plan is required for any public or private sewage system for the collection and conveyance of sewage to a treatment and disposal system that is regulated in accordance to the provisions of Chapter 26 of the Texas Water Code.
A treatment and disposal system includes the following:
- 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 down gradient 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.
The forms and associated material to complete a SCS plan can obtain online through Texas Commission on Environmental Quality (TCEQ). Additional information is required with the SCS plan such as location maps, site plans, geologic assessment, plan and profile views of the sewage collection system lines, construction details sheets, calculations, and construction notes. The construction plans of the sewage system must be certified by a registered Texas Professional Engineer. Prior to initiating any types of constructions, an SCS plan must be submitted for review and approved by TCEQ.
