When you have a home that relies on a septic system, there may come a time, even with all of the proper system care and septic tank cleaning, that your system begins to fail you. If this is the case, you will need to begin considering the possibility that you will need to replace your septic system entirely. However, before you do so, you should get to know some of the different types of available septic systems so that you can make the right selection for yourself and your home.
Standard Shallow vs Deeper Underground Septic Systems
Generally, there are two different types of septic systems in terms of how deep in the soil the system is installed. Standard septic systems are generally have tanks that are more shallowly installed. This means that the tank is closer to the ground level surface.
There are numerous benefits to having a standard (shallow) septic tank system. The ease of access for the tank if maintenance, draining, inspections, or repairs are needed is the primary benefit. They are also easier to install as less earth needs to be displaced for installation.
However, a standard shallow septic system may not be as effective as you would like it to be if you live right along the coast or right near the beaches. Recent research has found that as the climate continues to change and ocean water levels rise, the standard shallow septic system may not be able to properly filter waste water in the drain field.
A deeper septic system, on the other hand, may be able to properly filter the waste water in the soil before it gets into the sea water, preventing water contamination. The problem with deeper septic tanks is that they are more difficult to access if they require repairs and may be more costly to install initially.
Normal Drain Field vs Sand Mounds
There are also differences in septic systems in terms of the type of drain fields used to filter waste water. While the solid waste from your home plumbing system is maintained in the tank, the liquid is allowed to travel to the drain field to be processed by natural bacteria of microorganisms in the soil.
There are different ways to accomplish this liquid filtration goal. A standard or normal drain field for a septic tanks system is composed of long trenches coated in gravel and then covered in soil. Grass and other plants often grow in that soil, and the septic drain field looks like a normal lawn or landscaped area.
Sand mound absorption fields (or simply sand mounds) are an alternative to a normal drain field. These sand mounds are areas that rise from the plane of the ground. The filtration system is inside of the sand mound rather than underground. This type of system requires a pump to move the liquid from your septic tank up into the sand mound.
Sand mounds can be beneficial in that the absorption or drain field can be easily recognized and observed. It also allows a septic system to drain into an area that would not normally be usable as a drain field.
Keeping these varying options in mind, you can better determine what type of septic system will be right for your home. To learn more about which options are ideal for your home, contact companies like AAA Cesspool & Rooter Service.
