These are just to name a few! And really, you can't compare the different types - its like comparing apples v. oranges. Different purposes, different needs. In fact, there are so many different types of septic systems that it will make your head spin. And if it is making your head spin, you can almost guarantee others won't know the ins and outs of the system they have, what type of system they need, or even what their options are.
Wait... if my septic system is an aerobic system, does this mean it likes to work out?
Shocking, but the answer is no. But like an aerobic workout, an Aerobic Treatment Unit (ATU) uses oxygen to produce results. In the case of an ATU, oxygen is used to increase the production of natural bacteria to treat the wastewater that comes into the system. By injecting oxygen, good bacteria is put into hyper-speed, making the breakdown and processing of waste much more efficient, expediting the process of treatment.
Think about it like this: this is generally the same process that is used in a municipal setting, just on a much smaller, residential scale. Basically, you have to be able to treat the wastewater so it can effectively be re-purposed in a clean and safe manner.
Most everyone has heard of a Conventional Septic System, especially living in Texas. However, not many people know what it actually means. As you can guess, these are the more traditional types of systems, and are typically the most commonly used technology designed to treat wastewater.
Basically, a conventional, gravity flow system relies on just that. Gravity. It's divided up into multiple tanks or compartments, and then is re-distributed in a safe manner. Simple, right? Well, not really. You would actually be amazed at the level of science, engineering and biology that goes into the development of every system, even the conventional ones.
Most everyone has heard of Conventional Systems & Aerobic Systems, especially living in Texas. But have you ever heard of a Low-Pressure Dose (LPD) system?
A Low-Pressure Dose system is one that is confusing for a lot of people but is a really useful system that has a lot of versatility.
Basically, what a LPD system does, is act as a kind of hybrid between a conventional and an aerobic system. It is designed to treat your wastewater like a conventional but uses a pump to distribute wastewater several times a day, in a systematic manner, similar to an aerobic system.
Sounds simple, right? Well, that's because it is actually pretty straightforward.
Shockingly, yes. Evapotranspiration (also known as an ET system) is an ACTUAL thing, and one that is actually very important to the world of wastewater. It may not seem like a real thing, but we promise - it is... So instead of it being a word with too many letters, what is it exactly?
Well, an evapotranspiration bed treats wastewater by using the loss of water from the soil (evaporation) and the loss of water from the plants growing there (transpiration). Simple? It kind of is, actually, even though the name won't make you think it is. And the whole point of an ET bed is to give the homeowner an alternate way of dealing with the filtered wastewater.
There is a lot that goes into the design of an ET system (frequency of rain, type of soil, space available on the property to build, etc.). But that isn't really something you need to worry about; those are the types of things that a qualified wastewater company can design and figure out for your home. The main thing to know is ET beds still use a standard septic system to treat the water, they only differ on HOW the wastewater is taken care of after it's treated.
One of the great things about the ET system is that it can be used in clay soil. And since we are in Central Texas, an area with abundant clay soils, an ET system could be an alternate option to an aerobic system. When you're dealing with heavy clay soils, this system can be adapted to a wide-variety of property types. However, there is a catch. If you have an ET system, you must maintain your system by pumping and manually alternating the flow of waste to fields periodically via a manual valve.
How does the water get treated? Well it is designed to treat your wastewater like a conventional system but it just uses a unique, natural way of dealing with the sanitized wastewater. As well, like a conventional system, the ET system does not require a maintenance contract.
