Septic Systems

Conventional Systems

The conventional septic tank-absorption field home sewage treatment system is composed of two major elements: the septic tank and the soil absorption field. The septic tank (a settling and decomposition chamber) allows the sewage solids to separate from the liquid, undergo partial decomposition, and be stored as sludge at the bottom of the tank. The effluent from the septic tank then flows by gravity into the subsurface absorption field where it infiltrates into the soil.

Septic systems require care in site selection, design, and construction. Every individual conventional septic tank-absorption field system must be designed and constructed according to state and local requirements. A site evaluation can determine the type of system required.

Aerobic Systems

Aerobic septic systems are used in situations where conventional septic systems are not a viable option. In many cases, they replace failing septic systems. Aerobic systems are similar to septic systems in that they both use natural processes to treat wastewater. But unlike septic (anaerobic) treatment, the aerobic treatment process requires oxygen. There are two types of bacteria - anaerobic and aerobic. Aerobic bacteria work much faster than anaerobic bacteria which means they process septic tank waste more quickly. Aerobic treatment units use a mechanism to inject and circulate air inside the treatment tank that accelerates the treatment process. This mechanism requires electricity to operate. For this reason, aerobic systems cost more to operate and need more routine maintenance than most septic systems. However, when properly operated and maintained, aerobic systems can provide a high quality wastewater treatment alternative to septic systems.

At Swan Ditching Service, we recommend Hoot aerobic systems. The efficient five stage Hoot treatment system is designed with these components:

  1. The pretreatment Tank where the influent waters enter system. The aerobic decomposition of the influent begins here. It also holds any non-biodegradables inadvertently added to the system.

  2. The aeration chamber where oxygen is pumped into the wastewater. This is the heart of this activated sewage treatment system. The aeration thoroughly mixes the organic materials of the sewage with the bacterial population allowing the bacteria to attack and reduce the organic materials.

  3. In the clarifier chamber, the clear, odorless effluent rises. Any activated sludge settling in the final clarifier chamber is reintroduced into the aeration chamber by sewage movement in the aeration chamber.

  4. A chlorinator through which the clear effluents passes for disinfection.

  5. A holding tank where disinfected effluent is held for discharge.

  6. The aerator pump that is extremely quiet and efficient.

  7. A control center that monitors and controls the system.

  8. The discharge pump specially designed for Hoot Systems to discharge the effluent into a variety of disposal systems such as sprinklers or drainfields.
