A percolation test (colloquially called a perc test) is a test to determine the water absorption rate of soil (that is, its capacity for percolation) in preparation for the building of a septic drain field (leach field) or infiltration basin. [1] The results of a percolation test are required to design a septic system properly.
Many health departments require a percolation test ("perc" test) to establish the suitability of drain field soil to receive septic tank effluent. An engineer , soil scientist , or licensed designer may be required to work with the local governing agency to design a system that conforms to these criteria.
Dental percolation, increase rate of decay under crowns because of a conducive environment for strep mutants and lactobacillus; Potential sites for septic systems are tested by the "perc test". Example/theory: A hole (usually 6–10 inches in diameter) is dug in the ground surface (usually 12–24" deep).
All H2Ohio contracts must have current soil tests within the last 3-4 years. Nutrient Management Plans: This is the cornerstone practice of the statewide H2Ohio expansion. Developing nutrient ...
Mound systems are an alternative to the traditional rural septic system drain field. They are used in areas where septic systems are prone to failure from extremely permeable or impermeable soils, soil with the shallow cover over porous bedrock, and terrain that features a high water table.
A septic tank is an underground chamber made of concrete, fiberglass, or plastic through which domestic wastewater flows for basic sewage treatment. [2] Settling and anaerobic digestion processes reduce solids and organics, but the treatment efficiency is only moderate (referred to as "primary treatment"). [2]
