In this guide, we’ll walk you through everything you need to know about septic tank price, drain field

What Is a Septic System and How Does It Work?
A septic system is an underground wastewater treatment setup commonly used in homes without
access to municipal sewer lines. It typically consists of two main parts:
• The septic tank — where solid waste settles
• The drain field (leach field) — where liquid waste is filtered back into the soil
The system works by separating solids from liquids and allowing natural bacteria to break down waste.
The treated water is then safely dispersed into the ground through the drain field.

If you’re building a new home, the cost to put in a septic tank includes more than just the tank itself.

2. Labor and Excavation – Can make up 50% to 70% of total cost.
3. Permits and Testing – Soil testing ($700–$2,000), permits up to $2,300.
