In this article, we will discuss the steps involved in installing a septic tank and filtration field, as well as the importance of proper septic system maintenance to ensure its effectiveness.
Overview of Septic Tank and Filtration Field
Septic tanks and filtration fields are essential components of wastewater treatment systems for homes and buildings that are not connected to a municipal sewage system. These systems are designed to safely and effectively treat and dispose of household wastewater, including water from toilets, sinks, showers, and laundry machines.
Septic Tank
A septic tank is a watertight container buried underground that receives wastewater from the building’s plumbing system. The tank is typically made of concrete, fiberglass, or plastic and is divided into two chambers: one for solids and another for liquids. When wastewater enters the tank, solids settle to the bottom forming a layer of sludge, while grease and lighter solids float to the top creating a layer of scum.
As wastewater flows through the tank, it undergoes a natural separation process where solids are broken down by bacteria, and liquids are clarified. The clarified effluent then flows out of the tank and into the filtration field for further treatment.
Filtration Field
The filtration field, also known as a drain field or leach field, is a network of perforated pipes buried in trenches filled with gravel or other porous materials. The pipes distribute the clarified effluent from the septic tank evenly across the drain field, allowing the effluent to percolate through the soil.
The soil acts as a natural filter, removing harmful bacteria, viruses, and pollutants from the effluent before it drains into the groundwater or is evaporated into the atmosphere. Proper maintenance of the filtration field is crucial to ensure efficient treatment of wastewater and prevent contamination of the surrounding environment.
