What is a septic tank drain field and how does it work?
A septic tank drain field, also known as a leach field, is a critical part of your septic system in Berkeley. After wastewater leaves the septic tank, it flows into the drain field, which consists of a network of trenches containing gravel and perforated pipes. Here, the wastewater is further treated as it slowly percolates through the soil, removing contaminants before reaching groundwater. Proper functioning of the drain field is essential for preventing system backups and environmental contamination.
How does a septic tank work?
A septic tank in Berkeley works as a primary treatment system for wastewater. Solids and liquids from your home's plumbing enter the tank, where they are separated. Solids settle to the bottom as sludge, while lighter materials like grease float to the top as scum. Bacteria naturally present in the tank begin to break down some of the organic matter. The partially treated liquid, called effluent, then flows out of the tank to the drain field for further treatment in the soil.
