Abstract
A water treatment device, method and system with the water treatment device having a container for holding a water treatment material therein with the water treatment device including a shroud extending in a direction generally normal to a flow of debris laden water with the shroud inhibiting direct flow of debris into a water inlet in the water treatment device by directing water and debris over the shroud and around the water treatment device while a portion of the water can be directed laterally into the water treatment material within the water treatment device to thereby purify the water that flows over the water treatment materials with the water treatment device including multiple spaced and positioned water inlets so that the likelihood of the water inlet being completely obstructed is remote.
