| 説明 | A backhoe loader fills a toe drain with coarse sand as two workers from Thalle Construction level the fill material on Sept. 8, 2016. The sand is fine enough to maintain the integrity of the ditch but coarse enough to all water to pass through. The ditch runs around the perimeter of the Raw Water Storage Impoundment, a feature of the Savannah Harbor Expansion Project that mitigates impacts to city water. |
