Sand filter definition

Sand filter means an engineer designed OWTS that utilizes a layer of specified sand as filter and treatment media and incorporates pressure distribution.
Sand filter means a contained bed of sand that acts to filter the first flush of runoff. The runoff is then collected beneath the sand bed and conveyed to an adequate discharge point or infiltrated into the in-situ soils.
Sand filter means a system that utilizes a layer of specified sand as filter and treatment media and pressure distribution.

Sand filter means a contained bed of sand that acts to filter the first flush of runoff. The 1331 runoff is then collected beneath the sand bed and conveyed to an adequate discharge point or 1332 infiltrated into the in-situ soils. 1333 "Shallow marsh" means a zone within a stormwater extended detention basin that exists 1334 from the surface of the normal pool to a depth of six to 18 inches, and has a large surface area 1335 and, therefore, requires a reliable source of baseflow, groundwater supply, or a sizeable 1336 drainage area, to maintain the desired water surface elevations to support emergent vegetation. 1337 "Stormwater detention basin" or "detention basin" means a stormwater management facility 1338 that temporarily impounds runoff and discharges it through a hydraulic outlet structure to a 1339 downstream conveyance system. While a certain amount of outflow may also occur via 1340 infiltration through the surrounding soil, such amounts are negligible when compared to the 1341 outlet structure discharge rates and are, therefore, not considered in the facility's design. Since 1342 a detention facility impounds runoff only temporarily, it is normally dry during nonrainfall periods. 1343 "Stormwater extended detention basin" or "extended detention basin" means a stormwater 1344 management facility that temporarily impounds runoff and discharges it through a hydraulic 1345 outlet structure over a specified period of time to a downstream conveyance system for the 1346 purpose of water quality enhancement or stream channel erosion control. While a certain 1347 amount of outflow may also occur via infiltration through the surrounding soil, such amounts are 1348 negligible when compared to the outlet structure discharge rates and, therefore, are not 1349 considered in the facility's design. Since an extended detention basin impounds runoff only 1350 temporarily, it is normally dry during nonrainfall periods. 1351 "Stormwater extended detention basin-enhanced" or "extended detention basin-enhanced" 1352 means an extended detention basin modified to increase pollutant removal by providing a 1353 shallow marsh in the lower stage of the basin. 1354 "Stormwater retention basin" or "retention basin" means a stormwater management facility 1355 that includes a permanent impoundment, or normal pool of water, for the purpose of enhancing 1356 water quality and, therefore, is normally wet, even during nonrainfall periods. Storm runoff 1357 inflows may be temporarily stored ab...
