A King Vac® combination unit dug a 4-foot-by-6-foot tunnel, 90-feet long, under a shopping center mall to facilitate access to a broken water drain line. Once the drain line was repaired, the King Vac’s optional “Dry Bulk Blow-Off System” was used to back-fill the tunnel with dry sand.

A King Vac combination unit, equipped with a high pressure water jetting system, provided hydro-excavation to create a 12- foot-by-10-foot hole in the ground around a main cable junction box. This involved the simultaneous use of high pressure water and powerful vacuum to avoid damaging any of the optic cables and small control wires that were littered around the junction box.

One King Vac operation involved hooking up to a 1.5 mile long refinery product pipeline, maintaining a deep vacuum, and pulling a "pig" ,(a device slightly larger than the pipe diameter used to clean the inner wall), through the entire length of pipe. When this job was finished, the pipe was clean and the "pig" was unharmed and reusable.

At a U.S. northeastern refinery, a process unit needed internal emergency repairs that required the entire unit to be held under a full 27- inch vacuum (27-inch Hg.) for an indeterminable amount of time. The King Vac on this job was released from duty after successfully holding the required vacuum for 96 continuous hours.

After having owned a King Vac for only 6 months and not knowing its full capabilities, a company in California was approached by a boring contractor for a special project. The boring crew needed to lay a 30-inch pipe under a river, a distance of 540-feet. The current method was to put a man 35-feet below ground and manually remove the dirt created by drilling to a small buggy which was pulled out on a track. The King Vac operator devised a rigid 6-inch PVC pipe system that cradled the track and moved along behind the boring machine. The suction hose from the King Vac was attached to a shallow collection hopper which was fabricated and attached to the rear of the drill frame. The King Vac was able to pull the dirt 540-feet horizontally and 35-feet vertically.

During a long underground bore of 5,000-feet through the swamp lands of Florida, an unexpected "frac-out" (escape of drilling fluid through a weak part of soil within the drilling path) resulted in a drilling fluid release of over 200,000 gallons into a remote area of swamp land. After two unsuccessful attempts by the contractor to bring in vacuum trucks to clean-up the release, a King Vac owner in Florida was contacted. Working daylight to dark, the King Vac pulled 10-12 loads per day from distances 1,200-feet away from the truck and finished the job in 7 days.
