4 Types Of Septic Tanks

It is the layer of sand that treats the wastewater that is distributed in the pumps using a pump chamber and then collected at the bottom of the box. Once collected, the processed water is pumped into the drainage field and absorbed into the soil more easily. Alternative septic tank systems include aerobic septic systems, sand filter systems, choline septic system, surface distribution system, evaporation system, etc.

Septic evaporation tank systems are based on the natural evaporation of wastewater through a sand barrier level and a simultaneous perspiration of water through the leaves of plants and pastures planted on the drainage field. It is clear that these systems are more effective in the summer periods when the hours of sunlight provide the most effective wastewater treatment and are the most suitable for summer houses. Mound systems are installed when the soil available for treatment is minimal or the drainage field increases above ground level. The hill design is used when the bottom depth is insufficient to allow a conventional system. Bottom systems operate with a hill filled with sand that rises above the natural ground above a drainage field.

That is why the drainage field must be below the level of the actual septic tank. In addition, the base of the drains field grooves should be between 1 and 1.2 m above the groundwater level. This soil above ground water level works to treat wastewater and eliminate as many toxins as possible before returning to the environment. This system requires that the septic tank be made of reinforced concrete or plastic. As reported by WUFT News, septic tank facilities in Florida have increased since 2018, after ten years.

Wastewater is more common in urban areas, and septic tanks are more common outside of city limits for rural properties. Bottom systems are an option in areas with shallow soil depth, high groundwater, or shallow rocks. The effluent from the septic tank flows into a pump chamber where it is pumped up the Wastewater Expert Witness Engineer hill in prescribed doses. Effluent treatment takes place when it is discharged into the trench and filtered through the sand and then extended to the original soil. The composition of the floor around the house and the size of the house are two main factors that determine the best type of septic tank.

A perc test will determine how viable the underground soil is to properly manage and filter wastewater from septic tanks. A pipe network, often placed in a stone-filled ditch, distributes wastewater through the field with multiple drainage holes in the network. The size of the discharge field is proportional to the volume of the wastewater and inversely proportional to the porosity of the drainage field. The entire septic system can only function by gravity or, when topographic considerations require it, with the inclusion of a lift pump.
