Devices prevent debris and sediment from entering the BMP. Includes eavestrough or downspout screens, first flush diverters or filters on pipes leading to or from the cistern. Reduce the risk of obstructing [[inlets]], intakes or [[overflows|overflow outlet]] [[pipes]] and excessive sediment accumulation.
