Types Of Septic Design Texas

By Dorothy Price


A septic system is a self-contained, high efficient, wastewater treatment system that is located underground. Unlike the sewer systems, it treats and disposes wastewater from households onsite. For this reason, it is more economical to use. The system is also inexpensive to maintain and install. Furthermore, because its installation does not require a lot of space, it is environmental friendly. Outlined below are the four common types of septic design Texas.

First, the gravity system is one of the most popular and ancient designs in Texas. It has an elaborate drainfield that has pipes which are four inches wide. It is important to note that the pipes are supposed to be perforated and placed in trenches. The trenches are usually filled with gravity and have to be maintained three feet above any layer such as a water table.

As the effluent flows through the many pore spaces, it undergoes filtration. While the discharge moves through the soil, it is treated via numerous chemical and biological procedures. These processes ensure that the wastewater is free of impurities before it mixes with the underground water. It is important for the soil to be dry, permeable and oxygenated for the treatment to be a success.

Secondly, the pressure distribution drainfield is another common septic design system in Texas. This one, unlike the former, is most preferred in the specific areas that lack the right amount of space for the installation of the gravity model. It has a pump whose primary role is to distribute the effluent on the drainfield.

The model is additionally characterized with a network of pressurized lines. These lines offer a connection between the drainfield and the pump. The connection is important as it makes sure that the effluent is discharged into the drainfield at once. The system, moreover, has many layout options as opposed to the gravity model. When choosing your layout, therefore, it helps to carry out a research to determine the best fit layout design.

A sand filter system, on the other hand, is used when there is limited soil to facilitate the treatment process. In this system, a sand containment vessel is installed between the pressurized drainfield and the pump tank. The effluent is treated by the sand and proceeds to join the shallow soils on site. The sand filter can either be a PVC-lined box or concrete that is filled with sand.

The effluent from the septic tank is pumped in controlled portions to make sure that there is a uniform distribution. The effluent is treated as it moves through the particles of sand. It is then collected by an underground underdrain which either moves it to a second chamber for discharge or into a drain field that is pressurized.

For any site that is a mound and lacks an adequate soil depth, a mound system works best. A mound, in this case, is a type of drainfield that is elevated above the soil surface. It is also filled with a particular type of sand. Unlike the previous model, this one has gravel embedded in the sand and also in the pressurized pipes. The treatment of the effluent occurs as it moves through the sand particles into the surface soil.
