Which septic system is best?
The best choice is a precast concrete septic tank. Precast septic tanks hold many advantages over plastic, steel, or fiberglass tanks. This is why so many cities and towns actually require the use of concrete septic tanks.
How do conventional septic systems work?
In a conventional septic system, the majority of treatment occurs in the drainfield. Waste water flows from the tank through a solid pipe into a distribution box, where it is then channeled into perforated pipes set in trenches of gravel. The water slowly seeps into the underlying soil in the drainfield.
How do I know if I have an aerobic or anaerobic septic system?
May 24, 2021. Just like with aerobic and anaerobic exercise, these terms when applied to septic also relate to oxygen but refer to bacteria. Aerobic bacteria need oxygen to live, and anaerobic do not.
Which is better aerobic or anaerobic septic tank?
Even solid waste, which otherwise settles at the bottom in anaerobic septic system, is exposed to aerobic bacteria. Such a mechanism makes sure that the effluent is cleaner and easier to treat in the leach field. Aerobic systems are more efficient, but the installation process is more complicated, hence more expensive.
What is conventional sewer?
Executive Summary. Conventional gravity sewers are large networks of underground pipes that convey blackwater, greywater and, in many cases, stormwater from individual households to a (Semi-) Centralized Treatment facility, using gravity (and pumps when necessary).

What are the different types of septic systems?
There are three types of septic systems, categorized according to the manner in which they treat wastewater that enters the system as follows: 1 Type 1 Septic System: sewage is treated within a septic tank only before being discharged to a drain field where further treatment occurs naturally; 2 Type 2 Septic System: treatment takes place within a septic tank plus an additional aerobic secondary treatment stage, typically within a small scale on-site mechanical biological packaged treatment plant, before being discharged to a drain field; 3 Type 3 Septic System: this is a specially designed septic system that is capable of treating sewage to produce effluent of a higher quality standard, by including a disinfection process before being discharged into the environment via the drain field. Treatment takes place within an advanced on-site mechanical biological packaged treatment plant.

What is a septic tank?
They consist of a septic tank installed underground, which receives the wastewater. Once the wastewater is in the tank the suspended solids settle down to the bottom forming a layer of sludge, while the less dense oil, grease and fat floats to the surface forming a layer of scum.
What is an example of an anaerobic process involved in the breakdown of wastewater?

Why is discharged effluent important?
This is an important factor to consider when a property has poor quality soils or there is insufficient depth between the surface and the constricting layer or water table to adequately treat the effluent.
Gravity System
A gravity system consists of three parts: septic tank, drainfield, and soil beneath the drainfield. A gravity system requires at least 3 feet of native suitable soil beneath the drainfield.
Pressure Distribution System
Pressurized systems include a pump chamber that collects treated wastewater from the septic tank. A pressure distribution system is used when the soil and site conditions require controlled dosing, as when there's just 2-3 feet of native suitable soil beneath the drainfield.
Mound System
The mound is a drainfield bed that is raised above the natural soil surface with a specific sand fill material, all covered by suitable cover soil. They can be used when there's only 1 or 2 feet of native suitable soil. Within the sand fill is a gravel-filled or gravelless chamber bed with a network of small diameter pipes.
Sand Filter System
A typical sand filter is a PVC-lined or concrete box filled with a specific sand fill material. A network of small diameter pipes is placed in a gravel-filled or gravelless chamber bed on top of the sand. They can be used when there's only 1.5 feet of native suitable soil under the receiving drainfield.
Other Types
There are several other types of systems for use on properties that don't have enough native suitable soil depth to provide adequate treatment alone. Aerobic Treatment Units (ATU) and BioFilter systems are a couple system types in this category. Contact your local health department for more information on these types of systems.
Outdated Systems
In the past, many different containers have been used as septic tanks and they may no longer be safe or effective. Prior to the 1970s, septic tanks could have been made from cinderblocks, wood, 55-gallon drums, or concrete (manufactured or homemade). From about 1965 to 1975, single compartment concrete or steel tanks were common.
