Organic Sediment Removal Systems, LLC began in 1990, as a unique system to remove organic sediment from the bottom of ponds in an effort to restore them to their natural beauty. They work hard to remove muck, a substance that seals off the entire bottom of a pond, effectively clogging springs and stopping and ground flow of fresh water, leaving it stagnant and dying. The organic sediment is removed with a hydraulic system and divers, and is reused as top dressing and landscaping on site.
