The State of Florida has determined that certain water bodies in select areas, including Polk City, FL, contain excess nitrogen that lowers the quality of the water. This is caused, in part, by high-nitrogen water from area septic systems.
To combat the problem, the state in 2023 mandated that new septic systems and some replacement systems be installed as ATU septic systems (see below). Properties in Polk City, FL, that may be affected by House Bill 1379 include those that are less than one acre in size or contain large volumes of groundwater.
Lakeland Septic Company would like to share some helpful information on this subject.
What Is an ATU System?
The name for these higher-performing septic systems that you’ll hear most often in Polk City, FL, is “ATU system.” It stands for “aerobic treatment unit,” which is a simplified way of saying “enhanced nutrient-reducing/nitrogen-reducing onsite sewage treatment and disposal systems.”
The full name is complicated, but the work done by these systems is fairly straightforward: they add oxygen to the septic tank to more efficiently break down solids and reduce nitrogen levels in the effluent. Some studies indicate that a properly installed ATU system can reduce nitrogen levels by up to 75%.
The switch to high-oxygen ATU systems from standard septic systems will result in a positive reduction of nitrogen in bodies of water in and around Polk City, FL.
Will I Have to Replace My Existing Polk City FL Septic System?
You don’t have to replace your current septic system, but if you’re putting a brand-new system on a property that measures an acre or less within the designated areas, you’ll have to have it installed as an ATU system.
Replacing an existing system may not fall under the upgrade mandate. Check with Lakeland Septic in the Polk City, FL, area, and we’ll tell you how this legislation affects your specific property.
Do ATU Systems Work the Same as Regular Septic Systems?
Aside from the infusion of large amounts of oxygen, an ATU system does the same things a traditional septic system does. When it comes to how you use the system, there are no changes.
One difference is that ATU systems must be inspected more frequently than standard systems and only by authorized inspectors. Lakeland Septic provides these inspections.
All types of septic systems in Polk City, FL, and throughout the state rely on oxygen to energize bacteria, which break down solids in the tank. An ATU system simply adds more oxygen and makes the process more efficient.
As with standard systems, aerobic treatment units need to be professionally cleaned out regularly to prevent a variety of problems at your home, including:
- Sluggish toilets and slow drains
- Sewage backing up in sinks, tubs, and toilets
- Foul odors inside and outside the home
- Damp, soggy sections of ground above or near the septic tank
