"The MV800 is perfectly suited for fluid clean up on horizontal direction drilling (HDD) work sites," said Ditch Witch Product Manager Jason Proctor. "However, its usefulness certainly isn't limited to that - it's good for about any in-the-field clean-up task requiring a vacuum." However, the MV800's primary use is expected to be cleaning up drilling fluid, and if necessary, containing and transporting used drilling fluids for disposal. Drilling "mud" is an essential element in making an HDD installation, lubricating inside walls of the bore hole and carrying away cuttings as the pilot hole is drilled and then when it is enlarged during backreaming. Today, fluid clean up and removal are required on most jobs. Over the last decade, the standard equipment for these jobs have become the dual-purpose vacuum excavator, a vacuum and "soft" excavating machine, able to make precisely controlled excavations with high pressure water or air.
