How to Choose the Right Septic System for Your Home: A Comprehensive Guide

February 27, 2025

When it comes to selecting a septic system for your home, making the right choice is crucial for long-term efficiency, cost-effectiveness, and environmental sustainability. With various options available, homeowners need to consider multiple factors, including soil conditions, household size, and regulatory requirements. At Environmental Design Group, we specialize in residential septic system design and wastewater engineering treatment, helping homeowners in Austin, Texas, find the best solutions for their needs.

Understanding Septic Systems

A septic system is an underground wastewater treatment structure that processes and disposes of household sewage. It typically consists of a septic tank and a drain field (leach field). The septic tank separates solids from liquids, allowing bacteria to break down organic matter, while the drain field disperses the treated effluent safely into the soil.

Factors to Consider When Choosing a Septic System

1. Property Size and Soil Conditions

Soil type and absorption capacity significantly impact your septic system's functionality. A percolation test (or "perc test") determines how well the soil can absorb and filter wastewater. If your property has poor drainage, an alternative system, such as an aerobic treatment unit (ATU) or a mound system, may be necessary.


2. Household Size and Water Usage

The size of your household and daily water usage influence the septic system's capacity requirements. Larger families produce more wastewater, necessitating a bigger septic tank and drain field to prevent overloading the system.


3. Local Regulations and Permits

Septic system installations must comply with local health department regulations. In Austin, Texas, homeowners need proper permits and approvals before installation. Our team at Environmental Design Group offers septic permit coordination services to ensure compliance with all necessary regulations.


4. System Type Options

Several septic system types are available, each suited to different site conditions:

  • Conventional Septic System: Ideal for properties with suitable soil absorption rates.
  • Aerobic Treatment Unit (ATU): Uses oxygen to break down waste more efficiently, suitable for areas with poor soil conditions.
  • Mound System: A raised drain field designed for areas with shallow soil depth or high water tables.
  • Chamber System: A gravel-free alternative that works well in areas with low soil permeability.
  • Drip Distribution System: A slow-release system that evenly disperses effluent over a larger area.


5. Cost and Maintenance Considerations

Installation and long-term maintenance costs vary depending on the system type. While conventional systems tend to have lower upfront costs, alternative systems may require more maintenance but provide greater efficiency in challenging conditions. Regular maintenance, such as pumping and inspections, is crucial to ensure the longevity of your system.
