The water that ows over the ground is Grate inlets/catch basins/trench called stormwater or runoff and must be managed to avoiddrainsdamage to existing structures and land.Curb inletsUrbanized areas with buildings, roads, parking lots, or otherHeadwallsimpermeable surfaces tend to have more stormwater thanSafety end treatments (SETs)undeveloped areas. Because excess stormwater can increaseManholesthe potential for ooding and property damage, it is typicallyPipe and swalesdiverted into a stormwater drainage system called the storm Detention tankssewer. During a rain event, stormwater drains from the Trash screenscatchment areas via grate inlets and curb inlets into a series ofGrit and oil separatorsunderground piping. This storm sewer piping is placed at aNutrient treatment systemsdownward-sloping gradient to encourage water to ow on itsown, known as gravity-ow. The stormwater eventually owsinto a stream, river, ocean, or public estuary.Stormwater drainage infrastructures are predominantly made with unique precast concrete and eld-poured components.Many of these components can be pre-engineered and factorymanufactured, which offers quicker lead times, cost savings, and often better solutions.Visit drainage.parkusa.com for more information and design assistance.To request a quote or catalog, visit request.parkusa.com.APPLICATIONSGood to useCommercial Residential Municipal Industrial Low Impact in BMPsDevelopment'
