than 24 hours. If water is not draining completely from the sand filter in
24-hours, remove first 2-3 inches of discolored sand. Replace with new
sand. Sand that has been removed must be dewatered and appropriately
disposed in a landfill. At time that sand is maintained, sediment chamber

appropriately disposed in a landfill.
