Choosing the Right Septic System for your Prince William VA Home

Septic System Services

If you live in the rural area of Prince William, VA, you may need a septic system for your sewage needs and therefore septic tank installation may be in your future. Since there are no centralized sewage systems in many areas in this location, each home needs to take good care of its own waste management system.

Graveled Systems

The graveled system is one of the oldest designs around. It consists of have a septic tank, where some treatment of the waste is done, and a drain field network where waste is discharged into soil. In the soil, microorganisms will break down the organic elements in the waste.

The trick to get this system working well is to have the septic tank installation done well. A septic tank that does not push liquid fast enough into the drain field may cause the sewage to backflow into the toilets and sinks in the house. On the other hand, a septic tank that lets too much liquid flow through it may cause sewage in the drain field to flow up to the ground surface, endangering any form of life above the ground.

Low-Pressure Dosage Systems

Not all topographical conditions allow for a gravel system to be installed. The gravel system requires a flat ground. Many times, homes in Prince William, VA, are located in more confined areas, where the septic tank installation is done at a different height from the system’s drain field - which could be uphill. This may cause a pressure difference and it will require a different type of septic system.

In these cases, the system requires a standard septic tank and a separate tank that is known as a pumping chamber. The pressure pump in the separate tank will carry the waste up against gravity to the drain field. There, the waste liquid is released safely into the soil as with the graveled system.

If you have staying in Prince William, VA, where there could be topographical conditions that require a certain type of septic tank installation, call in SES company to help find the right setup for you.
