The Common 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.

The other frequently used design in Texas is the pressure distribution drainfield. The system is at most times efficient in areas that lack enough space for installing the previous design. The main distinction of this design is that it has a pump that releases the wastewater into the drain field at intervals.

This design is, moreover, composed of several pressurized lines which offer a link between the pump and the drainfield. The main advantage of this connection is ensuring that all wastewater is discharged at the same time. The other advantage of this system is that there are additional layout designs to select from. While determining the right layout for your site, therefore, it is important to consider all the available options.

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.

In this model, the wastewater is pumped in a controlled manner to facilitate a homogenous distribution. An underdrain then collects the wastewater as paves its way through the particles of sand. The resultant effluent can either be moved to a second compartment for discharge or be released into the drainfield.

The mound system, unlike the rest, is used in a site that has insufficient soil depth and is a mound. A mound is simply a drainfield that is slightly raised above the surface of the soil. It is, further, filled with a specific sand material. A gravel field is additionally situated within the sand and also in the network of pressurized pipes. The effluent is treated as it moves through the sand into the soil on the ground.
