If you live in a more rural part of Utah—like Heber, Park City, or the surrounding areas in Wasatch or Summit County—there’s a good chance your home relies on a septic system instead of a city sewer hookup. Whether you’re considering installing a new system or already have one in place, it’s important to understand the basics of septic tank lifespan, maintenance, and costs.

In this post, we’ll answer some of the most common questions homeowners have, so you can stay ahead of issues and make the best decision for your property.

Septic System Lifespan, Maintenance & Functionality

What is the average life of a septic system?

A well-installed and properly maintained septic system can last 20 to 40 years—sometimes even longer. The actual lifespan depends on several factors including the type of system, soil quality, water usage habits, and how often you pump your tank. Systems in areas like Wasatch County and Summit County that receive regular professional care often outlast those that are neglected.

How often should you drain a septic tank?

On average, you should pump your septic tank every 3 to 5 years. This can vary depending on your household size and usage. For example, a family of five in Heber may need more frequent pumping than a retired couple living in a smaller home.

Regular pumping helps prevent clogs, overflows, and drain field failure. If you’re unsure when your tank was last serviced, it’s a good idea to schedule an inspection.

How do you tell if your septic tank is full?

There are a few common signs that your septic tank might be full or failing:

• Slow drains in your sinks, showers, or toilets
  
• Bad odors around your yard or drain field
  
• Pooling water in the lawn, especially near the drain field
  
• Gurgling sounds in the plumbing
  

If you notice any of these issues, it’s important to call a professional to inspect your system before the problem gets worse.

What is the downside to a septic system?

Septic systems have many benefits, including independence from municipal utilities and lower monthly costs. However, there are a few downsides:

• Regular maintenance is required to avoid backups or expensive repairs.
  
• You need enough space for the drain field, which might not be ideal on small lots.
  
• They can be sensitive to what you flush—non-biodegradable products, grease, or excessive water can damage the system.
  

Still, for many homes in Utah’s mountain towns, septic systems are the best (and often the only) solution for onsite wastewater treatment.

What is the downfall of having a septic tank?

One of the main drawbacks is the potential for system failure if it’s not maintained properly. Neglect can lead to costly repairs, environmental damage, and even health hazards. In colder areas like Summit County, septic lines can freeze if not properly insulated or installed below the frost line.

That said, regular care and seasonal attention (like winter prep) go a long way toward preventing problems.

Am I on city sewer or septic?

Not sure if your property is on septic or sewer? Here are some ways to find out:

• Check your utility bill: If there’s no sewer charge, you’re probably on septic.
  
• Look for a septic tank cover in your yard—usually a round or rectangular lid.
  
• Call your local health department: They can often tell you if your area has access to municipal sewer systems.
  

If you live in more rural areas of Wasatch or Utah County, chances are you’re using an onsite septic system.

Cost of Septic Systems and Alternatives

What is the average cost to have a septic system installed?

The average cost to install a new septic system in Utah ranges from $8,000 to $15,000, depending on the size, type, and location of your property. Several factors affect the price:

• Soil conditions and slope (rocky terrain can be more expensive to excavate)
  
• Tank size (based on household size)
  
• Type of system (gravity-fed systems are cheaper than alternative systems)
  

In cities like Spanish Fork or Salem, installation might be less expensive due to easier access and softer soil, while homes in Park City with rocky backyards may need more complex excavation.

How much does it cost to put in a septic system?

Generally $10,000 to $20,000, or lower. Utah can offer more affordable and accessible options in many cases, particularly in less densely populated areas.

How much does an AWTS system cost?

An AWTS (Aerated Wastewater Treatment System) is a more advanced version of a septic system. It uses oxygen to break down waste more efficiently and can be ideal for small lots or environmentally sensitive areas.

These systems typically cost $15,000 to $25,000, depending on the complexity of installation and local permitting. While more expensive upfront, AWTS systems offer:

• Cleaner effluent discharge
  
• Better odor control
  
• Potential for greywater reuse
  

In certain zones of Summit County or near waterways in Park City, AWTS may be required or recommended by county health departments.
