Common Types of Septic Systems In Ohio
A Soil Absorption Field, or leach field, is the most common septic system for well drained soil. Wastewater flows from the septic tank into a network of perforated pipes or chambers, where it is distributed into the soil for natural treatment and disposal.
A Spray Irrigation System uses an aeration treatment unit to clean wastewater before it is disinfected and sprayed with a sprinkler head. The treated effluent is clean, clear, and odor-free, making these systems a great option for residential properties with soils that are not suitable for traditional leach fields, or wooded lots where a soil based system is difficult to install.
A Sand Mound System is used where natural soil conditions are not suitable for a conventional leach field. Treated wastewater is pumped into a raised sand bed, where it is filtered and dispersed into the surrounding soil.
An Off-Lot Discharge System, also called an NPDES system, is allowed for use on replacements, when the property is too small to fit a conventional system. An aeration unit treats the wastewater and discharges to an approved location, often a road ditch, buried culvert, or stream. The effluent is clear, clean, and odorless.
