Vertical separation means the depth of unsaturated, original, undisturbed soil of soil types 1-6 between the bottom infiltrative surface of a soil dispersal component and the highest seasonal water table, a restrictive layer, or soil type 7 as illustrated below by the profile drawing of subsurface soil absorption systems:
Vertical separation means the depth beneath the dispersal field infiltrative surface to a LC.
Vertical separation means the depth of unsaturated, original, undisturbed soil between the infiltrative surface of a drainfield component and the highest seasonal water table, a restrictive layer, or soil types 6 or 7 as illustrated by the profile drawings of drainfields in Figure 1 below.
Examples of Vertical separation in a sentence
Supplemental treatment systems shall be sited and designed so as to have a minimum vertical separation of twenty-four (24) inches to groundwater and eighteen (18) inches to restrictive or limiting layers and identified in the definition of Vertical Separation in this Chapter.
Operational policies should be developed or reviewed to ensure there are appropriate opportunities for pilots to exercise manual flying skills, such as in non-Reduced Vertical Separation Minimum airspace and during low workload conditions.
More Definitions of Vertical separation
Vertical separation means the vertical distance between the point of effluent application to the soil or the bottom of a trench or other excavation and a limiting feature of the soil treatment area such as seasonal high ground water, bedrock, or other restriction.
Vertical separation means the depth of unsaturated, original, undisturbed soil of soil types 1-6 between the bottom infiltrative surface of a soil dispersal
Vertical separation means the depth of effective soil that exists beneath the bottom of a dispersal component of the wastewater system and a restrictive or limit- ing layer or feature including, but not limited to:
Vertical separation means the depth of unsaturated soil below a leaching bed as measured from the bottom of the absorption trench or the bottom of the stone layer to a limiting surface such as high ground water table, rock or soil with a percolation time greater than 50 min/cm.
Vertical separation means the total depth of unsaturated soil that exists between the infiltrative surface of a distribution cell and limiting factor (as by redoximorphic features, groundwater or bedrock.
