Understanding Septic Tanks
Septic tanks are an essential part of a septic system, which is commonly used to treat and dispose of wastewater in areas where centralized sewage systems are not available. These tanks are underground containers designed to collect, separate, and store solid waste and scum from wastewater before it is discharged into the drain field for further treatment and absorption into the soil.
Definition and Function of Septic Tanks
A septic tank is a large, watertight container typically made of concrete, fiberglass, or plastic. It is buried underground and connected to the plumbing system of a property. The primary function of a septic tank is to hold and treat wastewater from toilets, sinks, showers, and other household drains.
Inside the tank, solid waste settles to the bottom forming a layer of sludge, while lighter materials such as oils and fats float to the top, creating a layer of scum. The liquid wastewater, known as effluent, flows out of the tank and into the drain field, where it undergoes further treatment by soil bacteria and filtration through the soil before it is safely absorbed.
Basic Types and Categories of Septic Tanks
Septic tanks come in various sizes, materials, and shapes to accommodate different property sizes and wastewater volumes. However, they can be broadly categorized into three types based on their material: concrete, fiberglass/plastic, and steel.
Concrete septic tanks are the most common type and are typically durable, long-lasting, and resistant to damage. Fiberglass and plastic tanks are lightweight and easier to transport and install. Steel tanks, although less common, can be more susceptible to corrosion and are often protected with external coatings.
