Infiltration BMPs definition

Infiltration BMPs means any treatment BMP designed primarily to percolate water into the subsurface. These include infiltration trench, infiltration basin, dry wells, permeable pavements without an under-drain, and sub-surface reservoir beds without an under-drain. BMPs that have some incidental infiltration but which are designed primarily to retain water or to treat water, such as bioretention, filter strips, permeable pavements with an under-drain, or vegetated/rock swales are not infiltration BMPs.
Infiltration BMPs or "infiltration facility" means any structural treatment BMP designed primarily to percolate water into the subsurface, such as an infiltration trench or infiltration basin. An infiltration facility may include filtering prior to or during infiltration. BMPs that infiltrate some water but which are designed primarily to retain water or to treat water, such as retention basins, constructed wetlands, or filtering swales are not infiltration facilities.

Examples of Infiltration BMPs in a sentence

  • Infiltration BMPs shall not be constructed nor receive runoff from disturbed areas until the entire contributory drainage area to the infiltration BMP has achieved final stabilization.

  • Infiltration BMPs shall include pretreatment BMPs unless shown to be unnecessary.

  • Infiltration BMPs are structural measures that capture, store and infiltrate storm water runoff.

  • Infiltration BMPs may only be installed within areas in which the tested infiltration rate falls between 0.1 and 10 inches per hour.

  • Infiltration BMPs include infiltration basins, infiltration trenches, infiltration galleries, bioretention without an underdrain, dry wells, and permeable pavement.

  • Infiltration BMPs shall be spread out, made as shallow as practicable, and located to maximize use of natural on-site infiltration features while still meeting the other requirements of this Ordinance.

  • Infiltration BMPs are not recommended for areas of industrial activity or areas subject to high vehicular traffic (25,000 or greater average daily traffic (ADT) on a main roadway or 15,000 or more ADT on any intersecting roadway) unless appropriate pretreatment is provided to ensure that groundwater is protected and the infiltration BMP is not rendered ineffective by overload.

  • Infiltration BMPs can also be limited in areas where slope instability/failure is a concern.

  • The Infiltration BMP(s) are permanent appurtenances to the Property, and Conveyance – As specifically identified in the Stormwater Management Site Plan (herein after “Plan”), a man-made, existing or proposed facility, structure or channel used for the transportation or transmission of stormwater from one place to another, including pipes, drainage ditches, channels and xxxxxx (vegetated and other), gutters, and like facilities or features.

  • Pervious pavements can be designed as Infiltration BMPs or as LID Principles1.

Related to Infiltration BMPs

  • Infiltration means water other than wastewater that enters a sewer system (including sewer system and foundation drains) from the ground through such means as defective pipes, pipe joints, connections, or manholes. Infiltration does not include, and is distinguished from, inflow.

  • Irradiation means the exposure of a living being or matter to ionizing radiation.

  • Added filtration means any filtration which is in addition to the inherent filtration.

  • Stray radiation means the sum of leakage and scattered radiation.

  • Fluoroscopic imaging assembly means a subsystem in which X-ray photons produce a visual image. It includes the image receptor(s) such as the image intensifier and spot-film device, electrical interlocks, if any, and structural material providing linkage between the image receptor and diagnostic source assembly.

  • Radionuclide means a radioactive element or a radioactive isotope.

  • Radiation therapy simulation system means a radiographic or fluoroscopic x-ray system intended for localizing the volume to be exposed during radiation therapy and confirming the position and size of the therapeutic irradiation field.
