Septic System Installation
New septic systems designed, permitted and installed to Alabama code — sized correctly for your soil, lot and household.
(256) 504-9653
SFI Environmental installs complete septic systems for new builds, replacements and failed systems across North and Central Alabama. We start below the surface: soil evaluation, percolation behaviour and lot layout decide the tank size, field line run and system type long before a shovel moves. Every installation is permitted, inspected and backfilled to Alabama Department of Public Health standards, then documented so you know exactly what is buried on your property and where.

Common questions
FAQ
- How long does a septic installation take?
- Most residential installations are completed in one to three days once permits are approved. Weather and soil conditions can extend excavation time.
- Do you handle the permits?
- Yes. We coordinate the county health department application, soil evaluation and final inspection as part of the installation.
- What size tank do I need?
- Tank size is driven by bedroom count and daily flow. Most Alabama homes fall between 1,000 and 1,500 gallons, but we size every system from the actual site data.
- What Happens During a Septic Installation?
- A new septic system is more than a tank buried in the yard. It is a complete wastewater treatment system that must match the property, household needs, soil, and local requirements. The process usually includes a site evaluation, system design, permits, excavation, tank installation, drain field construction, inspection, and final grading.
- How Long Does Septic Installation Take?
- The physical installation may take only a few days on a simple site, but the full process can take longer because of soil testing, design, permits, inspections, weather, equipment access, or special system requirements. Homeowners should plan for the whole process rather than focusing only on the excavation days.
- Can I choose any place in my yard for the drain field?
- No. Soil, slope, setbacks, and local requirements determine where a field can be placed.
- Does every septic system need a pump?
- No. Many systems work by gravity. Pumps are used when the layout or design requires them.
- Can I build over a septic tank or drain field?
- Septic areas should generally remain accessible and free of structures or heavy loads.
