If you’re like most homeowners with a septic system, you care about keeping it running smoothly and preventing costly repairs. One option some people consider to improve their system’s efficiency and safety is adding ultraviolet (UV) light. But is it the right choice for your septic system? Septic Blue of Raleigh breaks it down so you can make an informed decision with a septic company in Apex, NC.

What Is UV Light Treatment in a Septic System?

Ultraviolet (UV) light treatment uses powerful light rays to kill harmful bacteria and viruses in the water leaving your septic system. It’s a final step in cleaning the water before it’s released into the environment.

How Does UV Light Work?

A UV light system is usually installed in the septic tank’s effluent (the water leaving the system) pipe. After the septic cleaning inside your tank, the water passes through the UV light chamber for disinfection. By the time it exits, it’s much safer for the environment.

Benefits of UV Light in Septic Systems

Adding UV light to your septic system offers several advantages:

Better Water Quality
UV light treatment ensures that harmful bacteria and pathogens are removed from the water before it’s released. This is especially important if your septic system serves a home in an environmentally sensitive area or near water sources.
Improved Environmental Safety
Septic systems already help protect the environment by treating wastewater. A UV light system improves this by ensuring the water is cleaner, reducing the risk of contamination to nearby soil and groundwater.
No Chemicals Needed
Unlike some other disinfection methods, UV light doesn’t use harsh chemicals. This makes it safer for your property, the environment, and even the workers who perform septic pumping or cleaning for you.

Maintenance Is Key
Like any other part of your septic system, a UV light system needs regular care. To stay effective, the bulbs must be cleaned and replaced periodically. A trusted septic company can help you maintain this system.
Electricity Usage
Since UV light systems run on electricity, they add to your energy costs.
Not a Replacement for Septic Service
Even with UV light, you still need regular septic pumping and cleaning. UV light only disinfects the water after it has gone through the tank. Always keep up with your regular septic service schedule to avoid more significant problems down the line.

When Should You Consider UV Light?

Here are a few situations where UV light could be a good fit for your septic system:

You Live in an Environmentally Sensitive Area
If your home is near wetlands, rivers, or lakes, UV light can add a layer of protection to keep those areas clean and safe.
You Want Extra Peace of Mind
Knowing that your septic system produces cleaner water can be reassuring, especially if you have children or pets who might come into contact with treated areas.
You Need to Meet Local Regulations
In some areas, UV light treatment is required by law for homes with septic systems. Check with your local septic company or environmental agency to see if it’s necessary for your property.

What Else Should You Do to Keep Your Septic System Healthy?

While UV light can be a helpful addition, it’s not the only thing your septic system needs. Here are some tips:

Schedule Regular Septic Pumping
Pumping removes the solids that build up in your tank over time. Your tank can overflow without it, causing costly damage and potential health risks.
Hire Professionals for Septic Cleaning
Septic cleaning goes beyond pumping. It ensures your entire system, including pipes and filters, stays top shape. A professional septic service can handle this for you.
Work with a Reliable Septic Company
Partnering with a septic company you trust makes maintenance easier. They can handle everything from pumping and cleaning to inspecting and repairing your system.
