Infiltration BMP definition

Infiltration BMP means a LID BMP that reduces stormwater runoff by capturing and infiltrating the runoff into in-situ soils or amended onsite soils. Examples of infiltration BMPs include infiltration basins, dry wells, and pervious pavement (Order No. R4-2012-0175).

  • Infiltration BMP loading rate percentages in the Recommendation Chart for Infiltration Stormwater Management BMPs in Carbonate Bedrock in Appendix D shall be calculated as follows: The area tributary to the infiltration BMP shall be weighted as follows: All disturbed areas to be made impervious: weight at 100% All disturbed areas to be made pervious: weight at 50% All undisturbed pervious areas: weight at 0%All existing impervious areas: weight at 100% C.

  • Infiltration BMP- A BMP that allows for the infiltration of stormwater into the subsurface soil as groundwater, which returns to the stream as baseflow.

  • In this sense, performance function as an evocation of the past, not only being used by the need to produce causal and sequential explanatory narratives, but by a resumption of its own experience.

  • Infiltration BMP a Infiltration testing not required, only necessary to prove infeasibility.b No minimum infiltration rate if underdrain is installed.Step 5: Determine Design Infiltration Rate● The measured infiltration rate determined in Step 4 shall be reduced using correction factors to account for site variability and number of tests conducted, uncertainty of the test method, and potential for long-term clogging due to siltation and bio-buildup.

  • A Multi‐Directional Infiltration BMP may be implemented to infiltrate water at these lower soil layers, thus allowing infiltration to occur at sites that otherwise would be infeasible.

  • Infiltration Basin/Infiltration TrenchesThe primary concern for devices that depend on infiltration to groundwater is that they must be properly sited and maintained so that they continue to drain rapidly and standing water does not occur.The Program is implementing a Water Board-funded Stormwater Infiltration BMP Feasibility Study, which will address siting, design, and maintenance of infiltration BMPs in the County.

  • The loading ratio of impervious area to bed bottom area must be considered in all Infiltration BMP designs.

Related to Infiltration BMP

  • 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.

  • Exfiltration means any unauthorized release of data from within an information system. This includes copying the data through covert network channels or the copying of data to unauthorized media.

  • Diatomaceous earth filtration means a process resulting in substantial particulate removal in which a precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum), and while the water is filtered by passing through the cake on the septum, additional filter media known as body feed is continuously added to the feed water to maintain the permeability of the filter cake.

  • Filtration means a process for removing particulate matter from water by passage through porous media.

  • Infiltration rate means the rate of water entry into the soil expressed as a depth of water per unit of time (e.g., inches per hour).

  • Membrane filtration means a pressure or vacuum driven separation process in which particulate matter larger than 1 micrometer is rejected by an engineered barrier, primarily through a size-exclusion mechanism, and which has a measurable removal efficiency of a target organism that can be verified through the application of a direct integrity test. This definition includes the common membrane technologies of microfiltration, ultrafiltration, nanofiltration, and reverse osmosis.

  • Infiltrative surface means designated interface where effluent moves from distribution media or a distribution product into treatment media or original soil. In standard trench or bed systems this will be the interface of the distribution media or product and in-situ soil. Two separate infiltrative surfaces will exist in a mound system and an unlined sand filter, one at the interface of the distribution media and fill sand, the other at the interface of the fill sand and in-situ soil.

  • High global warming potential hydrofluorocarbons means any hydrofluorocarbons in a particular end use for which EPA’s Significant New Alternatives Policy (SNAP) program has identified other acceptable alternatives that have lower global warming potential. The SNAP list of alternatives is found at 40 CFR part 82, subpart G, with supplemental tables of alternatives available at (http://www.epa.gov/snap/ ).
