Septic systems

Septic Systems are a type of onsite sewage facility used in areas that are not connected to a sewage system. They are common in rural areas and often consist of a septic tank and a drain field.

Overview

A septic system treats wastewater from household plumbing produced by bathrooms, kitchen drains, and laundry. A typical septic system consists of a septic tank and a drainfield, or soil absorption field.

Components

Septic Tank

The septic tank is a watertight box, usually made of concrete or fiberglass, with an inlet and outlet pipe. Wastewater flows from the home to the septic tank through the sewer pipe.

Drain Field

The drain field is a subsurface wastewater disposal facility used to remove contaminants and impurities from the liquid that emerges after anaerobic digestion in a septic tank.

Function

The primary function of the septic system is to separate solids from the wastewater flow, and then to break down and digest organic matter. The septic tank separates wastewater into three layers: solids (sludge), effluent, and fats, oils and greases (scum).

Maintenance

Regular maintenance of the septic system is essential to ensure its effective operation. This includes regular pumping of the septic tank to prevent the buildup of solids, which could cause the system to fail.

Environmental Impact

Septic systems can have a significant impact on the local environment, particularly if they are not properly maintained. Leaking or overflowing septic systems can contaminate local water sources, posing a risk to public health.
