Design and Components
The most common type of septic system is the conventional septic system, which consists of two main components: a septic tank and a drainfield. The septic tank is a buried, watertight container that holds the wastewater from your home. The tank separates solids from liquids, allowing the solids to settle to the bottom and the liquids to flow into the drainfield. The drainfield, also known as a leach field, is a shallow, underground system of perforated pipes that distribute the treated wastewater into the soil.
How they work
Conventional septic systems work by allowing gravity to transport wastewater from the home into the septic tank. The solids settle to the bottom of the tank, forming a layer of sludge, while the liquids pass into the drainfield. In the drainfield, the wastewater is further treated as it percolates through the soil, where beneficial bacteria and natural processes remove contaminants before the water reaches groundwater sources.
Pros and cons
Conventional septic systems have several advantages. They are simple in design, reliable, and can be cost-effective compared to other types of systems. They also have a long lifespan if properly maintained. However, they may not be suitable for all sites, particularly those with shallow soil, high groundwater levels, or steep slopes. In these cases, alternative septic systems may be necessary.
Cost to purchase and maintain
The cost of purchasing and installing a conventional septic system will vary depending on factors such as tank size, drainfield size, local labor costs, and permits. Maintenance costs are relatively low, consisting mainly of regular pumping of the septic tank every 3-5 years.
