Septic System Installation in Big Spring, TX

Installing a septic system in 2026 involves a structured process of site assessment, engineering design, and physical excavation. For most homeowners, professional installation is required to meet local health and environmental codes. 

The process goes as follows:

  1. Site Evaluation & Soil Testing: A licensed professional performs a Percolation (Perc) Test to determine the soil's absorption rate. This determines the size and type of drain field needed.
  2. System Design & Permitting: Based on soil results and bedroom count (e.g., a 3-bedroom home usually requires a 1,000-gallon tank), an engineer designs the system layout for local health department approval.
  3. Excavation: Heavy machinery is used to dig the main hole for the tank and trenches for the drain field lines.
  4. Tank Placement: The septic tank (concrete, plastic, or fiberglass) is lowered into the hole and leveled using a laser level and a gravel or sand base.
  5. Drain Field Installation: Perforated pipes are laid in trenches, often surrounded by washed rock or gravel to facilitate drainage.
  6. Plumbing Connections: Pipes are connected from the house to the tank and from the tank to the drain field, ensuring a slope of at least 1/4 inch per foot for gravity flow.
  7. Final Inspection & Backfilling: An inspector from the local health department must approve the installation before it is covered with soil and grass seed.
