If you live outside Sacramento’s municipal sewer network, your home likely depends on a septic system. It’s easy to overlook this crucial part of your property until something goes wrong. Septic systems quietly handle wastewater treatment, protecting both your household and the environment.
But not all systems are the same. Understanding the types of septic systems available helps homeowners make informed choices before installation or replacement. Whether you’re building a new home, upgrading an old tank, or solving drainage issues, knowing how each system works can save you thousands in maintenance and repair costs.
In this guide, we’ll explore the five main different types of septic systems, how they work, and which one might be the best type of septic system for your Sacramento property.
What Are Septic Systems and Why They Matter
A septic system is a self-contained wastewater treatment setup designed for homes not connected to public sewers. It uses natural and mechanical processes to treat and dispose of household wastewater safely underground.
At its core, a system includes two main parts: a septic tank and a drainfield. The tank separates solids from liquids while bacteria break down organic waste. The treated effluent then flows into the drainfield, filtering through soil before re-entering the groundwater.
Choosing the right type of septic system is crucial because factors like soil type, slope, water table, and local regulations affect performance. In Sacramento, where soil ranges from clay-heavy to sandy loam, system selection becomes vital for preventing backups or contamination.
A properly designed system ensures eco-friendly, efficient wastewater management. On the other hand, selecting the wrong setup can lead to costly failures. That’s why understanding what are different types of septic systems is essential for every homeowner.
The 5 Types of Septic Systems Explained
When it comes to residential wastewater management, there are five main types of septic systems commonly used in Sacramento. Each one is designed for specific soil conditions, property sizes, and budgets.
1. Conventional Septic System
A conventional septic system is the most common and widely used setup. It features a septic tank and a series of trenches or gravel-filled pipes known as the drainfield. Wastewater flows into the tank, where solids settle and bacteria break them down. The liquid effluent then moves into the drainfield for filtration.
- Best For: Homes with ample space and well-draining soil.
- Pros: Simple design, low cost, and easy to maintain.
- Cons: Not suitable for small lots or poor drainage areas.
This system is popular across Sacramento’s suburban and rural outskirts for its reliability. To keep it functioning efficiently, schedule regular septic tank cleaning and pumping every few years.
2. Chamber System
A chamber system is a modern upgrade to the conventional design. Instead of gravel, it uses plastic chambers that provide a larger surface area for wastewater treatment.
- Best For: Areas with variable soil or limited gravel availability.
- Pros: Easier installation and reduced footprint.
- Cons: Shorter lifespan if not properly maintained.
This system is ideal for Sacramento neighborhoods with mixed soil drainage. Homeowners can also consider lift station pumping services to maintain proper wastewater flow in sloped properties.
3. Aerobic Treatment Unit (ATU)
An aerobic treatment unit (ATU) operates like a small municipal wastewater plant. It injects oxygen into the wastewater to promote aerobic bacteria that break down waste more efficiently than anaerobic systems.
- Best For: Shallow soil, high groundwater, or poor drainage.
- Pros: Cleaner effluent and suitable for smaller lots.
- Cons: Requires more maintenance and uses electricity.
In the Sacramento Valley, ATUs are perfect for properties with clay-heavy soils that hinder natural filtration. Routine inspections and septic riser and lid installations can help improve accessibility for maintenance.
4. Drip Distribution System
A drip distribution system uses narrow tubing to distribute treated wastewater evenly through the soil. Effluent is pumped from the septic tank or ATU into drip lines that slowly release it for uniform absorption.
- Best For: Sloped or shallow-soil properties.
- Pros: Precise effluent control, great for uneven terrain.
- Cons: Higher installation and maintenance costs.
These systems are efficient in Sacramento’s hilly regions. Homeowners often pair them with tank locating and outlet baffle replacement services to maintain optimal system flow.
5. Mound System
A mound septic system is designed for areas where traditional systems won’t work due to high water tables or shallow bedrock. It involves building an elevated sand mound that filters wastewater before it returns to the soil.
- Best For: Wet or flood-prone areas.
- Pros: Ideal for environmental protection.
- Cons: More visible and requires regular upkeep.
Mound systems are common near Sacramento’s river areas, where flood prevention is essential. For long-term efficiency, schedule real estate septic system inspections to ensure system compliance before buying or selling a property.
Practical Applications and Use Cases
Choosing between different types of septic systems depends on your property’s terrain, space, and soil type. For example:
- Suburban Homes in Fair Oaks: Conventional or chamber systems offer the best balance of cost and efficiency.
- Rural Estates in Wilton: Mound systems protect groundwater where the water table is high.
- Compact Lots in Citrus Heights: Aerobic treatment units or drip systems are ideal for limited spaces.
Homeowners should always request a professional site evaluation before installation. Blue Ribbon Septic performs soil tests, slope assessments, and customized recommendations to determine the best type of septic system for your needs.
Expert Tips and Common Mistakes to Avoid
Installing a septic system is only the beginning. Long-term performance depends on consistent care.
- Schedule Regular Inspections: Have your system inspected every 1–3 years and pumped when needed. Regular service prevents sludge buildup and premature system failure.
- Avoid Overloading the System: Spread out water use, repair leaks, and use water-efficient fixtures to avoid strain.
- Keep Construction Away from the Drainfield: Do not build decks, patios, or driveways over the drainfield. This prevents compaction and pipe damage.
- Use Septic-Safe Products: Avoid chemical cleaners or antibacterial soaps that kill beneficial bacteria inside the tank.
- Know When to Upgrade: If you experience frequent backups, pooling water, or odors, it might be time to switch to an ATU or drip system.
