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