A system for removing sediment from water is disclosed. The exemplary embodiments described herein disclose a system with a chamber having a deck positioned inside to divide it into an upper chamber and a lower chamber. The deck may have a plurality of holes to hold filtration elements and also may have a ridge or a skirt or both. The filtration elements may be filter cartridges with multiple elongated filter elements that extend down into the lower chamber.
