The water line in and out continues to drain liquid out from the tank to the ground which is known as the drain field. Solid mass carried by the wastewater from the home flows into the tank and, with gravity, falls to the bottom of the while the water itself continues forward to draining.
Eventually, due to bacteria, the solid material breaks down in the tank and settles at the bottom. The big issue with a conventional system is the surrounding soil.
The dirt and soil need to be permeable enough that as water flow reaches the tank and then the drain field, it flows into the soil and eventually evaporates upwards into the air as the ground dries out. This is enhanced by a series of pipes from the drain tank into the drain field that allows the water to move forward and farther out into the field instead of saturating the immediate exit point.
The second concern with the conventional system involves the tank. Over time, even with bacteria and breaking down, the solid matter will build up inside the tank. This process is a good situation will take years, but it does occur. If the tank is not pumped regularly the material will eventually block up the flow and the new wastewater will back up into the house or building. Without maintenance, most owners find out about this problem the hard way during the rainy season or a big blockage event.
The conventional septic system design has been a proven approach for decades. Taken care of properly, these standard systems will last anywhere from 25 to 30 years before a full replacement is needed.
They are made from usually three different materials: concrete, fiberglass , or polyethylene. Older models that have needed serious replacement have oftentimes been concrete boxes that basically broke apart over time or were invaded by local plant or tree roots.
In some cases, the installation is a fairly straightforward matter. In others, it can be more complicated. No surprise, this variance ends up producing a range of costs that can go from affordable to prohibitive very quickly.
Poor draining situations can occur from a variety of causes. Some are simply due to much rock and impermeable material in the immediate area, and it would be far too expensive to drill out the lock or break it down to solve the problem. Swampy areas are notorious for this kind of situation.
Fortunately, alternative systems still allow water to be removed and let solid matter escape from the home or building with drainage. To compensate for a poor layer of soil, sand is used instead. Sand is extremely permeable for water, which flows through it extremely fast. Sand also collectively has a high density which blocks solid matter from moving forward.
With this approach, a sand drain field is essentially created producing the desired drainage effect not otherwise possible. We cover every state from Texas to Maine. Are you considering buying a new home that has a septic system? Here are a few questions you should ask before buying a home with a septic system. Nervous about buying a home with a septic system? Here are several reasons why septic is better than town sewer.
There are nearly septic system additives on the market today -- have you ever wondered if they work? Not all municipalities allow aerobic septic systems, so be sure to check with your town or city before completing a purchase. While aerobic septic systems are often used as replacements for existing failed gravity-powered septic systems they can be expensive to maintain and install.
Selecting an Aerobic Septic System Aerobic septic systems inject oxygen into sewage waste, stimulating the growth of aerobic bacteria, which break down and filter the wastewater and solids.
Copyright Septic Septic. Advantages of Aerobic Systems Aerobic systems have a few advantages over conventional septic systems: Aerobic systems can often be paired with a smaller leaching field than a similar conventional septic system. Disadvantages Despite these substantial benefits, aerobic systems are in generally limited use.
