Infiltration facility definition

Infiltration facility means a stormwater management facility that temporarily impounds runoff and discharges it via infiltration through the surrounding soil. While an infiltration facility may also be equipped with an outlet structure to discharge impounded runoff, such discharge is normally reserved for overflow and other emergency conditions. Since an infiltration facility impounds runoff only temporarily, it is normally dry during nonrainfall periods. Infiltration basin, infiltration trench, infiltration dry well, and porous pavement shall be considered infiltration facilities.
Infiltration facility means any structure or device designed to infiltrate retained water to the subsurface. These facilities may be above grade or below grade.
Infiltration facility means a drainage control facility that temporarily stores, and then percolates drainage water into the underlying soil.

Examples of Infiltration facility in a sentence

  • While design specifications are available for most of the secondary practices proposed, an “underground infiltration soak-away pit” (or Infiltration facility, Stormwater Design Specification 8) may prove useful in some situations and may be used in conditions where thesoil has moderate to high infiltration rates.

  • How to Size Infiltration facility for one inch of runoff Take the new Impervious areas square footage (Ia) and divided by twelve (12) to get the volume of water per cubic feet (Wv) required for storage for one inch of runoff.

  • Infiltration facility design includes the design of basins, ponds, trenches and other best management practices (BMP’s) developed to encourage infiltration of stormwater back into the ground.
