Knowing the basics of a septic tank design can be more advantageous than you think. In fact, I was surprised to know just how much of the cost of repairs and place replacements I can save just by knowing the right designs that an efficient drainage system should have. Most people would prefer to avail of the service of professionals and contractors, and there is nothing wrong with that, but it is also worth your time and energy to know what goes on when installing a septic tank system.

Proper Sizes

Setting up your own septic tank system can be more complicated than we think. More than just pipes and drains, a whole system consists of a very large tank and an even larger drain field or leach field. A septic tank system design typically shows the tank as being connected to the water lines from the house. There are then pipes for the water to pass through from the tank to the drainfields where the treated water will be absorbed by the soil after further treatment. Ideally, a septic tank can hold at least 1000 gal of water to make it efficient. The holding capacity of the tank allows the water and the wastes to separate before they are transported in to the drain field and then into the soil.

Drainfield Requirements

More than just the size of the tank, I find that many people tend to downgrade the importance of the size of the drainfields. This is the last area of treatment and is oftentimes the site where most problems occur. When it comes to creating a septic tank leach field design, the surface area is more relevant than the simple volume capacity of the whole area. This is because the microorganisms that eat on the organic wastes in the water attach themselves to rocks and other soil particles. They form a jelly-like film or layer that thickens over time. Of course, the more spread out this layer is, the better. Installing the proper septic tank drainfield design can keep drainfield problems from occurring prematurely.

Design Criteria

The cost of septic tank system replacement and the installation of new ones are quite costly, and therefore there must be certain criteria that have to be met during each and every installation. A concrete septic tank design first has to have the proper configuration for the tank, the leach fields, and all the pipes and drains and leach lines that need to be set up. There is also the option for what type of material to be used, whether to use concrete septic tanks or to employ the use of plastic ones or even those made from fiberglass. The difference is that although fiberglass and plastic products are easier to move and transport, they are more prone to floating and being deformed than their concrete counterparts.

 

Other Factors

I was also told that the water-tightness of the system is a very relevant factor when it comes to securing the safety of the environment and all members of the community. Moreover, the implications of the design to the operation and maintenance of the whole system also weighed heavily upon me as repair cost can be very expensive.
