b'GENERAL INFORMATION ParkUSA RainFilter is a complete ParkUSA RainFilter is a complete system designed to treat total suspended solidssystem designed to treat (TSS), debris, and trash from stormwater runoff. It presents a low footprint and TSS, debris, and trash from is of special use on LEED projects, and green developments, among others. stormwater runoff. It presents It consists of an HDPE construction tank, an internal stainless-steel filter, and a low footprint and is of special an optimal storage system. use on LEED projects, and green developments, among others.In forested areas, the water balance or natural hydrology is altered only by rainfall and associated fluctuations in infiltration, evaporation and transpiration fromFEATURESplant growth. But in urban areas this natural hydrology is heavily modified,Various Basket and Storage because land has been cleared of vegetation and capped with hard or imperviousEquipment Designs Availablesurfaces. When it rains, most rainfall runs off impervious surfaces such as roofs and roads and is typically transported directly and quickly to waterways throughLow Profile Design Installationa drainage system. As a result, stormwater reaches waterways more often, moreLEED Compliantquickly and in greater volumes than waterways are naturally adapted to as thereTexas Manufacturedare limited opportunities for infiltration, evaporation and transpiration via plants Easy Installation and in the landscape. MaintenanceIn this way, the ParkUSA RainFilter is useful for any project where prefiltrationis needed, plus it contributes to flow control in waterways.SYSTEM COMPONENTSThe RainFilter is designed with the following components: Stainless-steel Basket Screen HDPE Tank Stormwater Storage Equipment as Required Piping OPERATIONParkUSAs RainFilter captures unwanted floatable pollutants from stormwater systems. Inside of the unit the influent will encounter a floatable collection stainless-steel basket that traps floating debris as small as 2000 micron in size, preventing them from invading municipal drainages. The separated effluent will exit the RainFilter and continue through the optional stormwater storage system, leaving behind the debris in the product.DESIGN CONSIDERATIONSBasin is constructed of high density polyethylene drainage pipe conformingto ASTM F1648. All extruded welding shall be per ASTM F2880. At the same time,the basket and tabs are to be constructed of 16 gauge stainless steel 304 perforated plate. The basket lip is to be constructed of 14 gauge 304 plate.Lower overflow orifice to be constructed of stainless steel perforated cylinder. Finally, manhole frames, covers or grates area manufactured of grey cast iron conforming to ASTM A48 Class 30. Manhole shall have 24 inches inside diameterand traffic duty.228'
