There are several different types of drain fields used in today’s septic systems. Beyond conventional drain fields, you also have dry well systems, chamber-type systems and mound-type drain fields.
Let’s take a look at these common types of drain fields and how they differ from each other. Here’s some information from our septic tank cleaning company in Bay City, MI.
Dry well systems
Dry well drain fields do not use the gravel troughs and perforated pipes you’d find in a more conventional drain field configuration. Instead, they are made with large pits that get filled with gravel or crushed rock, which provide essentially the same purification and filtration benefits you’d get in a standard system. These systems can be a little less effective at filtering wastewater simply because there’s less surface area, but they are still considered extremely durable and reliable, and effective enough that they can be used in certain situations to filter wastewater.
This is a relatively new method of drain field development, in which the system holds fluids inside a plastic container and lets them slowly seep into the ground beneath without any sort of gravel bed being present. These systems do not tend to last as long as other types of systems, and thus will come with a shorter warranty period. However, their low cost does make them rather popular in areas where they’re allowed by local codes and ordinances.
Keep in mind, however, that chamber systems require a very particular type of soil composition if they’re to be put into use. They also require more hands-on work from the property owner, as they must be frequently monitored to ensure there is no overflowing or leaking occurring, especially if the soil type does not provide sufficient absorption for the amount of wastewater being produced.
Mound drain fields
In some cases, the type of soil or ground conditions in your area can prevent the installation of a standard drain field in the soil. Mound systems, then, get built up above the ground, and thus often need an extra pump to push wastewater to the top of the drain field. When the wastewater arrives in the mound system, the process then proceeds in a way that’s very similar to the process a conventional drain field employs.
In the long run, the amount of time these drain fields last depends heavily on the quality and methods of construction, as well as the quality of the soil located just below the mound. If you’re unsure about the soil quality in your area, this might not necessarily be the best choice of drain field for you.
These are just three examples of common drain field setups that may or may not be an option on your property, depending on the conditions of your soil and ground.
