About this service
A septic tank is an underground chamber made of concrete, plastic, or fiberglass that collects all the wastewater from your home. It acts as a primary treatment unit where solids sink to the bottom, oils float to the top, and liquid flows out to the drain field. It is the heart of your home's waste system. Proper maintenance is essential to ensure it doesn't overflow or fail, which can lead to costly repairs and environmental issues on your property.

How does a septic tank work for homeowners in Lewisville, Texas?
A septic tank in Lewisville, Texas, functions as a decentralized wastewater treatment system. When you use water, it flows from your home into the underground tank. Inside the tank, solids settle to the bottom as sludge, and lighter materials like grease rise to the top as scum. The partially treated liquid, or effluent, then flows out to a drain field, where it is naturally filtered and purified by the soil. This process is vital for properties not connected to the municipal sewer system in Lewisville.

What is a septic distribution box and its role in Lewisville systems?
A septic distribution box, or d-box, plays a key role in septic systems in Lewisville, Texas. It's typically located between the septic tank and the drain field. Its primary function is to evenly distribute the effluent from the tank to all sections of the drain field. This even distribution ensures that the entire drain field is used effectively, preventing overloading in one area and promoting proper wastewater treatment. A properly functioning d-box is essential for the longevity and efficiency of your Lewisville septic system.
What types of septic systems are commonly used in Lewisville?
In Lewisville, Texas, the most common type of septic system is the conventional system, consisting of a septic tank and a subsurface drain field.

These can include aerobic treatment units (ATUs), which provide a higher level of treatment, or engineered systems designed for challenging sites.
