When most people think about septic systems, they picture underground tanks buried deep in the soil. However, in certain situations, an above-ground septic tank can be a smarter and more practical choice. For instance, considering Tucson’s unique desert terrain, rocky soil, and sometimes limited property space, it can be a good option for homeowners and businesses.
What Is an Above Ground Septic Tank?
An above-ground septic tank is as its name suggests; a waste storage and treatment tank that sits on or partially above the surface rather than being fully buried. These tanks function similarly to traditional underground systems, collecting and processing wastewater from your home or business.
These tanks are often made of durable materials such as plastic, fiberglass, or concrete, designed to withstand weather and long-term use. Above-ground septic tanks are often used where digging or underground installation is not viable. In essence, they offer property owners a reliable way to manage waste without extensive excavation.
Situations Where You May Need an Above Ground Septic Tank
Not every property in Tucson is suited for an underground septic tank. Below are some common situations where an above ground system might be the best option:
- Poor Soil Conditions
Septic systems depend on soil to filter wastewater safely. If your property has soil with poor drainage, clay-heavy ground, or soil that cannot properly absorb water, you may need an above ground septic tank.
- High Water table Areas
In areas where the water table is close to the surface, underground septic tanks risk contaminating groundwater or flooding. An above ground system reduces that risk by keeping the tank elevated and separated from the water table.
- Rocky or Shallow Bedrock Terrain
Many Tucson properties have rocky landscapes or shallow bedrock, which makes digging expensive and difficult. Installing an above ground septic tank avoids costly excavation while still providing efficient waste management.
- Temporary Installations
For construction sites, mobile housing units, or other temporary projects, above-ground septic tanks are an ideal solution. They can be set up quickly, moved when needed, and removed without major disruption to the property.
- Small or Uneven Properties
If your property lacks the space required for a conventional underground system or is on a slope where installation would be challenging, an above ground tank may fit more easily into your layout.
- Older Properties or Replacements
In some cases, you may not be able to replace an older septic system with another underground tank due to property limitations. An above ground provides a modern solution without requiring major landscape disruption.
Benefits of Above Ground Septic Tanks
Choosing an above ground septic tank has several advantages, especially in Tucson’s unique environment:
- Easier installation – since there is no need for deep excavation, installation is often faster and more cost-effective.
- Lower costs in challenging terrain – Properties with rocky or clay-heavy soil can avoid expensive digging costs.
- Simplified maintenance and inspections – Because the tank is more accessible, routine maintenance, pumping, and inspections are easier and less disruptive.
- Versatility – Suitable for both residential homes and commercial properties, as well as for temporary uses.
Things to Consider Before Choosing One
While above-ground septic tanks offer many benefits, there are important considerations to keep in mind before installing one, including:
- Local regulations. Tucson and Pima County have rules and permit requirements for septic systems. Always check compliance before installation.
- Maintenance needs. These tanks may require more frequent inspections to ensure they are functioning properly.
- Aesthetic impact. Being above ground, the tank will be visible unless landscaped or concealed.
- Professional installation. To avoid leaks, odor issues, and compliance problems, a licensed septic professional should handle all installation needs.
