Septic System Install
Licensed septic system installer
Septic systems are essential for managing household wastewater in areas without access to municipal sewer systems. Proper installation is crucial for ensuring the system’s efficiency, longevity, and environmental safety. This guide provides a step-by-step overview of the septic system installation process, including planning, design, installation, and maintenance.
What is a Septic System?
A septic system is an underground wastewater treatment structure, typically used in rural areas. It consists of a septic tank and a drain field (or leach field). The septic tank digests organic matter and separates floatable matter (e.g., oils and grease) and solids from the wastewater. The liquid (known as effluent) then flows into the drain field, where it is naturally filtered by the soil.
Types of Septic Systems
- Conventional Systems: Standard systems with a septic tank and a trench or bed subsurface wastewater infiltration system.
- Chamber Systems: An alternative to the gravel/stone system.
- Drip Distribution Systems: Used where there is a shallow soil depth, restrictive layer, or minimal slope.
- Mound Systems: Constructed above ground to overcome soil or site restrictions.
- Recirculating Sand Filter Systems: Used for sites with poor soil conditions or high water tables.

Planning and Design
Site Evaluation
A thorough site evaluation is the first step. This includes:
- Soil Testing: To determine the soil’s absorption capacity.
- Topography: Understanding the slope and layout of the land.
- Water Table Level: Ensuring the system is above the high water table.
System Design
Designing a septic system involves:
- Sizing the Septic Tank: Based on the number of bedrooms or the size of the home.
- Drain Field Design: Determining the size and layout of the drain field based on soil tests and household size.
- Permits and Regulations: Obtaining necessary permits and adhering to local health department regulations.
Installation Process
Excavation and Tank Placement
- Excavation: Digging the hole for the septic tank and trenches for the drain field.
- Placing the Tank: Installing the septic tank in the excavated area and ensuring it is level.
Piping and Drain Field Installation
- Connecting Pipes: Running pipes from the house to the septic tank and from the tank to the drain field.
- Drain Field Construction: Installing the drain field, which may involve laying gravel, perforated pipes, or chambers.
Backfilling and Covering
- Backfilling: Covering the tank and drain field with soil, ensuring proper grading to prevent surface water from pooling over the system.
- Final Inspection: Having the installation inspected by local authorities to ensure it meets all requirements.
Maintenance and Care
Regular Maintenance
- Pump the Tank: Regular pumping (every 3-5 years) to remove sludge and scum.
- Inspect the System: Regular inspections to check for leaks or other issues.
- Water Usage: Conserving water to reduce the load on the septic system.
Avoiding Damage
- Protect the Drain Field: Avoid driving or parking on the drain field to prevent soil compaction.
- Mindful Landscaping: Plant grass or shallow-rooted plants over the drain field; avoid deep-rooted trees and shrubs.
