Introduction to Building a 2 Barrel Septic System
Building a 2 barrel septic system is a practical solution for managing wastewater in areas without access to municipal sewer systems. This type of septic system is designed to treat and dispose of household sewage efficiently, ensuring that your property remains sanitary and environmentally friendly. While it may seem like a daunting task, with the right knowledge and tools, constructing a 2 barrel septic system can be a straightforward process.
The primary function of a septic system is to separate solids from liquids, allowing for the safe breakdown of organic matter by bacteria. A 2 barrel system typically consists of two interconnected tanks that work in tandem to enhance the treatment process. The first tank, known as the septic tank, receives wastewater from your home. Here, solids settle to the bottom, forming sludge, while lighter materials like grease float to the top, creating scum. The liquid effluent then flows into the second tank, where further treatment occurs before the effluent is discharged into a drain field.
Understanding the components and functionality of a 2 barrel septic system is crucial for effective installation and maintenance. It’s essential to select the right materials, ensure proper sizing, and adhere to local regulations. This guide will walk you through each step of the process, from planning and excavation to installation and maintenance.
Before diving into the construction process, it’s important to note that building a septic system is not just about digging holes and placing tanks. It requires careful planning, knowledge of local codes, and an understanding of soil conditions. Improper installation can lead to system failure, costly repairs, and environmental contamination. Therefore, it’s vital to approach this project with a clear understanding of the requirements and best practices.
In this comprehensive guide, we will cover the essential aspects of building a 2 barrel septic system, including materials needed, step-by-step instructions, and practical tips for success. Whether you are a seasoned DIY enthusiast or a first-time builder, this guide aims to equip you with the knowledge necessary to complete your septic system project efficiently and effectively.

Constructing Your 2 Barrel Septic System: A Step-by-Step Guide
Building a 2 barrel septic system requires careful planning, the right materials, and a clear understanding of the installation process. This section will provide a detailed overview of each step involved in constructing your septic system, ensuring that you have the knowledge needed to complete the project successfully.
Understanding Local Regulations
Before you start digging, familiarize yourself with local regulations regarding septic systems. Each area has specific codes that dictate:
– Permits Required: Obtain the necessary permits before beginning construction.
– System Specifications: Understand the size and design requirements for your system based on the number of bedrooms in your home and the expected wastewater flow.
– Inspection Protocols: Know the inspection process to ensure compliance with local health departments.
Materials Needed
Gather the following materials before starting the construction of your septic system:
– Two Septic Tanks: Typically made of concrete or fiberglass.
– PVC Pipes: For connecting the tanks and leading to the drain field.
– Gravel: For drainage and to create a leach field.
– Soil: For backfilling around the tanks.
– Tools: Shovel, level, pipe cutter, and safety gear.
Site Preparation
Choosing the right location for your septic system is crucial. Follow these steps:
1. Select a Site: Look for a flat area away from water sources, such as wells or streams.
2. Conduct a Soil Test: Determine soil permeability to ensure proper drainage.
3. Mark the Area: Clearly outline the area where the tanks and drain field will be installed.
Excavation Process
Once your site is prepared, begin the excavation:
– Dig the Trenches: Create two trenches for the septic tanks, ensuring they are level and deep enough to accommodate the tanks.
– Ensure Proper Slope: The tanks should be installed with a slight slope to facilitate the flow of wastewater.
Installing the Septic Tanks
With the trenches ready, it’s time to install the tanks:
1. Place the First Tank: Lower the first septic tank into the trench, ensuring it is level.
2. Connect the Tanks: Use PVC pipes to connect the first tank to the second tank.
3. Backfill: Carefully backfill around the tanks with soil, ensuring no voids are left.
Setting Up the Drain Field
The drain field is essential for dispersing treated effluent:
– Create Trenches: Dig trenches for the drain field, typically 1-3 feet deep and 2-3 feet wide.
– Add Gravel: Place a layer of gravel at the bottom of each trench to promote drainage.
– Install Perforated Pipes: Lay perforated PVC pipes on top of the gravel, ensuring they are sloped for proper drainage.
Final Steps and Maintenance
After installation, there are several final steps to ensure your septic system functions correctly:
– Cover the Trenches: Fill the trenches with soil, leaving the surface level.
– Mark the System: Clearly mark the location of your septic system to avoid damage during future landscaping or construction.
– Regular Maintenance: Schedule regular inspections and pumping of the tanks every 3-5 years to prevent clogs and system failure.
Conclusion
Practical Recommendations for Building a 2 Barrel Septic System
Constructing a 2 barrel septic system can be a rewarding project, but it requires attention to detail and adherence to best practices. Here are actionable recommendations to ensure your system is built effectively and operates smoothly.
Planning and Preparation
1. Conduct Thorough Research
Before starting, invest time in understanding septic systems. Familiarize yourself with:
– Local regulations and codes
– Soil types and their drainage capabilities
– The necessary permits and inspection requirements
2. Create a Detailed Plan
Draft a comprehensive plan that includes:
– Site layout
– Dimensions of tanks and trenches
– Drain field design
This plan will serve as a roadmap for your project.
Material Selection
3. Choose Quality Materials
Select durable materials to ensure longevity:
– Septic Tanks: Opt for high-quality concrete or fiberglass tanks that meet local standards.
– Pipes: Use schedule 40 PVC pipes for durability and resistance to corrosion.
4. Invest in Proper Tools
Having the right tools will make the installation process smoother. Essential tools include:
– Excavator or backhoe for digging
– Level for ensuring proper alignment
– Pipe cutter for precise cuts
Installation Process
5. Follow a Step-by-Step Approach
Stick to the following sequence during installation:
1. Excavate the Site: Ensure trenches are deep and level.
2. Install the First Tank: Place it securely and level it.
