A storage lagoon for backwash sediment at this New York water filtration plant needed its sediment removed for future operations. A 30′ circumference by 100′ long Geotube® was selected to dewater the residuals for removal to a landfill. The plant employees were trained on the installation and operations of the chemical feed system and Geotube®. The facility manager reported he had pumped the entire lagoon full of residuals into the tube and was very pleased with the results.
