IMS, Division of Liquid Waste Technology, LLC started in 1986 in Olathe, KS with the primary focus of providing submersible pumps and one-truck transportable dredges to the waste water industry. IMS quickly became a leader in the waste water dredge market, but in 1996 diversified its markets due to increased demand for easier to use dredges.
 In 1996 IMS developed the patented Starwheel Drive self-propulsion system (U.S. patent 5,782,660) which has revolutionized the way people dredge by eliminating the use of restrictive anchor cables.
IMS has since earned itself the reputation of being the world's leading producer of one-truck transportable self-propelled dredging systems and has delivered more dredges for lake, marina, and canal maintenance projects than any other manufacturer.
IMS also developed the Weedmaster (patent pending) cutterhead which converts the Versi-Dredge® into a weed harvesting system. This allows the end user to tackle a wider variety of projects with a single piece of equipment instead having several pieces with multiple operators.
 In 2000 the Governor of the State of Kansas presented IMS President, Jim Horton, with the Kansas Exporter of the Year Award. In early 2003 IMS was acquired by its competitor Liquid Waste Technology.
Today IMS has sold hundreds of dredging systems worldwide to over 45 countries around the globe.
IMS has sales offices around the globe with its International Sales Office located in Kansas City. IMS’s factory is located 40 minutes East of Minneapolis / St. Paul International Airport in New Richmond, WI. IMS’s new state-of-the-art 90,000 ft2 (8,361m2) factory is equipped with a training facility, demonstration pond, two story office building, and hydraulic / electric clean rooms. After being open for less than 2 months at the new factory the Board of Directors approved 100% expansion of the factory due to high demand for IMS and affiliated products.
IMS and its affiliates are the largest group of dredge companies in the Americas and have one of the largest dredge building facilities in the world. IMS and its affiliates have over 200 years of collective experience in the design and manufacture of hydraulic dredging systems. In 2010 IMS and its affiliates were acquired by Markel Ventures a subsidiary of Markel Corp. (MKL-NYSE).
